Spinal epidural hematoma is a well known complication of spinal surgery. Clinically insignificant small epidural hematomas develop in most spinal surgeries following laminectomy. However, the incidence of clinically significant postoperative spinal epidural hematomas that result in neurological deficits is extremely rare. In this report, we present a 33-year-old female patient whose spinal surgery resulted in postoperative spinal epidural hematoma. She was diagnosed with lumbar disc disease and underwent hemipartial lumbar laminectomy and discectomy. After twelve hours postoperation, her neurologic status deteriorated and cauda equina syndrome with acute spinal epidural hematoma was identified. She was immediately treated with surgical decompression and evacuation of the hematoma. The incidence of epidural hematoma after spinal surgery is rare, but very serious complication. Spinal epidural hematomas can cause significant spinal cord and cauda equina compression, requiring surgical intervention. Once diagnosed, the patient should immediately undergo emergency surgical exploration and evacuation of the hematoma.
Although postoperative spinal epidural hematoma (SEH) is not uncommon, hematomas that require surgery are rare. Cauda equina syndrome (CES) may be associated with postoperative SEH. In these cases, early recognition and emergency decompression can prevent further damage and better neurologic recovery.
A 41-year-old man underwent two-level discectomy with insertion of an interspinous spacer at L3-4 and L4-5 because of low back pain and radiculopathy. Eight hours after the operation, the patient developed CES. MRI revealed SEH compressing posteriorly at the L3-4 level. On emergency decompression and hematoma evacuation, the interspinous spacer had obstructed the laminotomy site at L3-4 completely, blocking drainage to the drain. The patient experienced complete neurologic recovery by 2 months followup.
Many studies report risk factors for SEH. However, postoperative SEH can also be encountered in patients without these risks. One study reported a critical ratio (preoperative versus postoperative cross-sectional area) correlated with postoperative symptoms, especially in those with CES. The propensity to develop CES is likely dependent on a number of patient-specific factors.
Surgeons should be aware that patients without risk factors may develop acute CES. Wider laminotomy (larger than half of the device size) may help to prevent this complication when one uses the compressible type of device, especially in patients with relatively small lamina.
Spinal epidural hematoma (SEH) represents the most frequent entity of acute or chronic spinal bleeding. Based upon pathogenesis, SEH can be classified as idiopathic, spontaneous, and secondary. The idiopathic forms are considered not to be attributed to any specific risk factors. Spontaneous SEH, accounting for 0.3–0.9% of all spinal epidural space occupying lesions, instead is associated with risk factors (such as substantial soft trauma or coagulation abnormalities). The chronic form, as our literature review revealed, is the rarest and its most frequent location is the lumbar spine. The pathophysiology of spontaneous and idiopathic SEH is still under debate: There are only a few reports in literature of chronically evolving SEH with progressively increasing pain and neurological impairment. Magnetic resonance imaging may be inconclusive for differential diagnosis. Here, we present two cases of lumbar chronic SEH with slow, progressive, and persistent lumbar radicular impairment. The first patient reported a minor trauma with slight back contusion and thus was classified as spontaneous SEH. In the second case not even a minor trauma was involved, so we considered it to be idiopathic SEH. In both cases preoperative blood and coagulation tests were normal and we did not find any other or co-factors in the patients’ clinical histories. MR imaging showed uncertain spinal canal obstructing lesions at L3 and L4 level in both cases. Surgical treatment allowed a correct diagnosis and resulted in full clinical and neuroradiological recovery after 1 year follow-up. Our aim is to discuss pathogenesis, clinical and radiological features, differential diagnosis and treatment options, on the background of relevant literature review.

The purpose of this case report is to describe a rare case of a cervicothoracic spinal epidural hematoma (SEH) after anterior cervical spine surgery. A 60-year-old man complained of severe neck and arm pain 4 hours after anterior cervical discectomy and fusion at the C5-6 level. Magnetic resonance imaging revealed a postoperative SEH extending from C1 to T4. Direct hemostasis and drainage of loculated hematoma at the C5-6 level completely improved the patient's condition. When a patient complains of severe neck and/or arm pain after anterior cervical spinal surgery, though rare, the possibility of a postoperative SEH extending to non-decompressed, adjacent levels should be considered as with our case.

We describe a case of acute lumbar epidural hematoma at the L2-3 level complicated by paraplegia, which occurred after coagulation disorder because of massive bleeding intraoperatively in cesarean section. The preoperative coagulation laboratory finding was in normal range and so we tried combined spinal epidural anesthesia. Uterine atony occurred in the operation, and there was persistant bleeding during and after the operation. After the operation, she complained of paresthesia on her both legs and was diagnosed with epidural hematoma (EDH) by radiologic examination. Emergency laminectomy on lumbar spine was carried out for hematoma evacuation and decompression of the epidural space at once. In our experience, massive bleeding during surgery may potentially increase the risk of EDH postoperatively.

Intracranial hemorrhage is a serious but rare complication of spinal surgery, which can occur in the intracerebral, cerebellar, epidural, or subdural compartment.
To describe patients with intracranial hemorrhage after lumbar spinal surgery and present clinical and diagnostic imaging findings.
In this retrospective study, medical records of 1,077 patients who underwent lumbar spinal surgery in our tertiary referral neurosurgery center between January 2003 and September 2010 were studied. The original presentations of the patients before the surgical intervention were herniated lumbar disc, spinal canal stenosis, spondylolisthesis, lumbar spinal trauma, and lumbar spine and epidural tumor. The operations performed consisted of discectomy, multiple level laminectomy, stabilization and fusion, lumbar instrumentation, and lumbar spinal and epidural tumor resection.
Four cases developed intracranial hemorrhage including acute subdural hematoma (one case), epidural hematoma (one case), and remote cerebellar hemorrhage (two cases). The clinical and diagnostic imaging characteristics along with treatments performed and outcomes of these four patients are described and the pertinent literature regarding post-lumbar spinal surgery intracranial hemorrhages is reviewed.
Though rare, intracranial hemorrhage can occur following lumbar spinal surgery. This complication may be asymptomatic or manifest with intense headache at early stages any time during the first week after surgery. Dural tear, bloody CSF leakage, focal neurologic symptoms, and headache are indicators of potential intracranial hemorrhage, which should be considered during or following surgery and necessitate diagnostic imaging.

There are no reports of a 7-day delay in the onset of neurological deterioration because of a spinal epidural hematoma (SEH) after a spinal fracture. A hematoma was detected from the T12 to L2 area in a 36-year-old male patient with a T12 burst fracture. On the same day, the patient underwent in situ posterior pedicle instrumentation on T10-L3 with no additional laminectomy. On the seventh postoperative day, the patient suddenly developed weakness and sensory changes in both extremities, together with a sharp pain. A MRI showed that the hematoma had definitely increased in size. A partial laminectomy was performed 12 hours after the onset of symptoms. Two days after surgery, recovery of neurological function was noted. This case shows that spinal surgeons need to be aware of the possible occurrence of a delayed aggravated SEH and neurological deterioration after a spinal fracture.

Spontaneous spinal epidural hematoma is a relatively rare but potentially disabling disease. Prompt timely surgical management may promote recovery even in severe cases.
We report a 34-year-old man with a 2-hour history of sudden severe back pain, followed by weakness and numbness over the bilateral lower limbs, progressing to intense paraparesis and anesthesia. A spinal magnetic resonance imaging scan was performed and revealed an anterior epidural hematoma of the thoracic spine. He underwent an emergency decompression laminectomy of the thoracic spine and hematoma evacuation. Just after surgery, his lower extremity movements improved. After 1 week, there was no residual weakness and ambulation without assistance was resumed, with residual paresthesia on the plantar face of both feet. After 5 months, no residual symptoms persisted.
The diagnosis of spontaneous spinal epidural hematoma must be kept in mind in cases of sudden back pain with symptoms of spinal cord compression. Early recognition, accurate diagnosis and prompt surgical treatment may result in significant improvement even in severe cases.
A 67-year-old man with degenerative lumbar spinal stenosis and a medical history significant for coronary artery disease underwent routine lumbar surgical decompression. The objective of this study was to report a case of postoperative epidural hematoma associated with the use of emergent anticoagulation, including the dangers associated with spinal decompression and early postoperative anticoagulation.
After anticoagulation therapy for postoperative myocardial ischemia, the patient developed paresis with ascending abdominal paraesthesias. Immediate decompression of the surgical wound was carried out at the bedside. Magnetic resonance imaging revealed a massive spinal epidural hematoma extending from the middle of the cervical spine to the sacrum. Emergent cervical, thoracic, and revision lumbar laminectomy without fusion was performed to decompress the spinal canal and evacuate the hematoma.
Motor and sensory function returned to normal by 14 days postoperatively, but bowel and bladder function continued to be impaired. Postoperative radiographs showed that coronal and sagittal spinal alignment did not change significantly after extensive laminectomy.
Full anticoagulation should be avoided in the early postoperative period. In cases requiring early vigorous anticoagulation, patients should be closely monitored for changes in neurologic status. Combined cervical, thoracic, and lumbar laminectomy, without instrumentation or fusion, is an acceptable treatment option.

We report three cases of spontaneous spinal epidural hematoma (SSEH) with hemiparesis. The first patient was a 73-year-old woman who presented with left hemiparesis, neck pain, and left shoulder pain. A cervical MRI scan revealed a left posterolateral epidural hematoma at the C3–C6 level. The condition of the patient improved after laminectomy and evacuation of the epidural hematoma. The second patient was a 62-year-old man who presented with right hemiparesis and neck pain. A cervical MRI scan revealed a right posterolateral dominant epidural hematoma at the C6-T1 level. The condition of the patient improved after laminectomy and evacuation of the epidural hematoma. The third patient was a 60-year-old woman who presented with left hemiparesis and neck pain. A cervical MRI scan revealed a left posterolateral epidural hematoma at the C2–C4 level. The condition of the patient improved with conservative treatment. The classical clinical presentation of SSEH is acute onset of severe irradiating back pain followed by progression to paralysis, whereas SSEH with hemiparesis is less common. Our cases suggest that acute cervical spinal epidural hematoma should be considered as a differential diagnosis in patients presenting with clinical symptoms of sudden neck pain and radicular pain with progression to hemiparesis.
We report a series of epidural hematomas which cause neurologic deterioration after spinal surgery, and have taken risk factors and prognostic factors into consideration. We retrospectively reviewed the database of 3720 cases of spine operation in a single institute over 7 years (1998 April-2005 July). Nine patients who demonstrated neurologic deterioration after surgery and required surgical decompression were identified. Factors postulated to increase the postoperative epidural hematoma and to improve neurologic outcome were investigated. The incidence of postoperative epidural hematoma was 0.24%. Operation sites were cervical 3 cases, thoracic 2 cases, and lumbar 4 cases. Their original diagnoses were tumor 3 cases, cervical stenosis 2 cases, lumbar stenosis 3 cases and herniated lumbar disc 1case. The symptoms of epidural hematomas were neurologic deterioration and pain. After decompression, clinical outcome revealed complete recovery in 3 cases (33.3%), incomplete recovery in 5 cases (55.6%) and no change in 1 case (11.1%). Factors increasing the risk of postoperative epidural hematoma were coagulopathy from medical illness or anticoagulation therapy (4 cases, 44.4%) and highly vascularized tumor (3 cases, 33.3%). The time interval to evacuation of complete recovery group (29.3 hours) was shorter than incomplete recovery group (66.3 hours). Patients with coagulopathy and highly vascularized tumor were more vulnerable to spinal epidural hematoma. The postoperative outcome was related to the preoperative neurological deficit and the time interval to the decompression.

Spinal epidural hematoma (SEH) causing acute myelopathy is rare. The usual clinical presentation of a SEH is sudden severe neck or back pain that progresses toward paraparesis or quadriparesis, depending on the level of the lesion. Recent studies have shown that early decompressive surgery is very important for patient's recovery. We experienced five patients of cervico-thoracic epidural hematomas associated with neurologic deficits that were treated successfully with surgical intervention.

Early postoperative MRI after spinal surgery is difficult to interpret because of confounding postoperative mass effects and frequent occurrence of epidural hematomas. Purpose of this prospective study is to evaluate prevalence, extent and significance of hematoma in the first postoperative week in asymptomatic patients after decompression for lumbar stenosis and to determine the degree of clinically significant dura compression by comparing with the patients with postoperative symptoms. MRI was performed in 30 asymptomatic patients (47 levels) in the first week after lumbar spine decompression for degenerative stenosis. Eleven patients requiring surgical revision (16 levels) for symptomatic early postoperative hematoma were used for comparison. In both groups the cross-sectional area of the maximum dural compression (bony stenosis and dural sac expansion) was measured preoperatively and postoperatively by an experienced radiologist. Epidural hematoma was seen in 42.5% in asymptomatic patients (20/47 levels). The median area of postoperative hematoma at the operated level was 176 mm2 in asymptomatic patients and 365 mm2 in symptomatic patients. The median cross-sectional area of the dural sac at the operated level was 128.5 and 0 mm2 in asymptomatic and symptomatic patients, respectively, at the site of maximal compression. In the symptomatic group 75% of the patients had a maximal postoperative dural sac area of 58.5 mm2 or less, whereas in the asymptomatic group 75% of patients with epidural hematoma had an area of 75 mm2 or more. The size of hematoma and the degree of dural sac compression were significantly larger in patients with symptoms needing surgical revision. Dural sac area of less than 75 mm2 in early postoperative MRI was found to be the threshold for clinical significance.

We present a rare case of delayed onset of epidural hematoma after lumbar surgery whose only presenting symptom was vesicorectal disturbance. A 68-year-old man with degenerative spinal stenosis underwent lumbar decompression and instrumented posterolateral spine fusion. The day after his discharge following an unremarkable postoperative course, he presented to the emergency room complaining of difficulty in urination. An MRI revealed an epidural fluid collection causing compression of the thecal sac. The fluid was evacuated, revealing a postoperative hematoma. After removal of the hematoma, his symptoms disappeared immediately, and his urinary function completely recovered. Most reports have characterized postoperative epidural hematoma as occurring early after operation and accompanied with neurological deficits. But it can happen even two weeks after spinal surgery with no pain. Surgeons thus may need to follow up patients for at least a few weeks because some complications, such as epidural hematomas, could take that long to manifest themselves.
An 80-year-old white male suffered a stroke, fell to the floor, and suffered acute right hemiparesis and facial palsy. After an intravenous alteplase infusion 2.5 h later, the patient first complained of numbness in his right arm, then neck pain, followed by left leg numbness and slowly progressing paraparesis. MRI of the spine demonstrated an acute spinal dorsal epidural hematoma extending from the C6 to the T6 level; 12 h later, he underwent hematoma evacuation and laminectomy. Three months after surgery, the patient was paraplegic with moderate sensory loss below mamillary level. Acute ischemic stroke is often associated with a sudden fall, which, after thrombolysis, may result in unusual hemorrhagic complications.

Study design: A case report.
Objective: To report a rare case of acute spinal subdural hematoma (SSH) complicating lumbar spine surgery, its characteristic presenting symptoms, diagnostic imaging, possible cause, and pitfall in management.
Methods: A 59-year-old woman with lumbar spinal instability and stenosis underwent laminectomy and decompression at L3–L5 with instrumentation and fusion from L3–S1.
Results: Immediately following surgery, the patient presented with incapacitating pain of both lower extremities from the mid-thigh downward, which was not relieved by narcotic analgesia and was disproportional to surgical trauma. Left ankle and great toes weakness was detected at postoperative day 2 and deteriorated on day 6. Magnetic resonance imaging was performed urgently and revealed a characteristic SSH with thecal sac compression at the level of L2, proximal to the laminectomy. Emergency decompression and evacuation of the hematoma was performed. The patient had partial recovery 6 weeks postoperatively.
Conclusion: Acute SSH is a rare complication of lumbar spine surgery. This diagnosis must be considered when severe leg pain, unresolved with analgesia and disproportional to surgical trauma, with neurological deterioration occurring after lumbar spine surgery. Magnetic resonance imaging is the imaging modality of choice to assist in the differential diagnosis of an SSH. Early surgical decompression is necessary for optimal neurological recovery.
Neurological deficits following epidural or spinal anesthesia are extremely rare. Transient paraplegia following epidural anesthesia in a patient with thoracic disc herniation has been presented. A 44-year-old woman developed paraplegia during the operation for vascular surgery of her legs under epidural anesthesia. Epidural hematoma or spinal cord ischemia was ruled out by magnetic resonance imaging of the thoracic and lumbar spine in which protruded disc at T11-12 level compressing the spinal cord has been verified. Patient responded well to steroid treatment and rehabilitation interventions. Physicians should be aware of preceding disc protrusions, which may have detrimental effects on spinal cord perfusion, as a cause of persistent or transient paraplegia before epidural anesthesia procedure. MRI is a valuable imaging option to rule out epidural anesthesia complications and coexisting pathologies like disc herniations.
Spontaneous intracranial hypotension (SIH), typically presents with orthostatic headache, low pressure on lumbar tapping, and diffuse pachymeningeal enhancement on magnetic resonance imaging. SIH is often accompanied by subdural fluid collections, which in most cases responds to conservative treatment or spinal epidural blood patch. Several authors advocate that large subdural hematoma with acute deterioration merits surgical drainage; however, few have reported complications following craniotomy. We describe a complicated case of SIH, which was initially diagnosed as acute subarachnoid hemorrhage with bilateral chronic subdural hematoma (SDH), due to unusual presentation. Burr hole drainage of subdural hematoma was performed due to progressive decrease of consciousness, which then resulted in a huge postoperative epidural hematoma collection. Prompt hematoma evacuation did not restore the patient's consciousness but aggravated downward brain herniation. Trendelenburg position and spinal epidural blood patch achieved a rapid improvement in patient's consciousness. This case indicates that the surgical drainage for chronic SDH in SIH can lead to serious complications and it should be cautiously considered.

Posterior epidural migration of thoracic disc herniation is extremely rare but may occur in the same manner as in the lumbar spine.
A 53-year-old Japanese man experienced sudden onset of incomplete paraplegia after lifting a heavy object. Magnetic resonance imaging revealed a posterior epidural mass compressing the spinal cord at the T9-T10 level. The patient underwent emergency surgery consisting of laminectomy at T9-T10 with right medial facetectomy, removal of the mass lesion, and posterior instrumented fusion. Histological examination of the mass lesion yielded findings consistent with sequestered disc material. His symptoms resolved, and he was able to resume walking without a cane 4 weeks after surgery.
Pre-operative diagnosis of posterior epidural migration of herniated thoracic disc based on magnetic resonance imaging alone may be overlooked, given the rarity of this pathology. However, this entity should be considered among the differential diagnoses for an enhancing posterior thoracic extradural mass.

Ligamentum flavum hematoma is a rare condition. Twenty cases including present case have been reported in English-language literature. Among them, only one case reported in pure thoracic spine. A 72-year-old man presented with thoracic myelopathy without precedent cause. Magnetic resonance images revealed a posterior semicircular mass which was located in T7 and T8 level compressing the spinal cord dorsally. T7-8 total laminectomy and extirpation of the mass was performed. One month later following surgery, the patient fully recovered to normal state. Pathologic result was confirmed as ligamentum flavum hematoma. Ligamentum flavum hematoma of rigid thoracic spine is a very rare disease entity. Most reported cases were confined to mobile cervical and lumbar spine. Surgeons should be aware that there seems to be another different pathogenesis
other than previously reported cases of mobile cervical and lumbar spine.

Closed-suction drainage is commonly used for prevention of postoperative hematoma and associated neurologic compromise after lumbar decompression, but it remains unclear whether suction drainage reduces postoperative complications.
We evaluated the efficacy of closed-suction drainage in single-level lumbar decompression surgery.
Patients and Methods
We retrospectively reviewed 560 patients who underwent single-level lumbar decompression or discectomy. We routinely used closed-suction drainage in all spinal surgeries until July 2003, and thereafter, we did not use drains in single-level lumbar decompression surgery. These two groups (298 patients in the group that received drains, 262 in the group that did not receive drains) were compared for rates of wound infection and epidural hematoma.
Mean operating time (55 versus 56 minutes) and intraoperative blood loss (64 versus 57 mL) were not different between the two groups. None of 560 patients had a wound infection requiring surgical intervention. The rate of postoperative hematoma was 0.7% in the group that received drains (two of 298 patients) and 0% in the group that did not receive drains (zero of 262 patients).
In this study, the risk of wound infection and hematomas in single-level lumbar decompression surgery was not influenced by use of a drain. The use of postoperative wound drainage in patients with potential risk for epidural bleeding in situations such as multiple-level decompression, instrumentation surgery, anticoagulant therapy, trauma, and tumors or metastases needs additional study.

Spinal epidural haematoma (SEH) is a rare complication of haemophilia. A 3-month-old boy presenting with non-traumatic acute onset quadriparesis was found to have SEH on MRI scan. On further investigations, diagnosis of severe haemophilia A was confirmed. He responded well to conservative treatment with replacement of factor VIII without any need for surgical decompression. Neurological recovery was complete. We believe this is the youngest reported case of haemophilia presenting with spontaneous SEH. Another peculiarity of this case is absence of excessive bleeding due to forceps and vacuum application, circumcision and intramuscular injection, even in the presence of severe haemophilia. This case calls attention to the clinical features, radiological appearances and management options of this rare complication of SEH in people with haemophilia.
Chronic spinal epidural hematoma related to Kummell's disease is extremely rare. An 82-year-old woman who had been managed conservatively for seven weeks with the diagnosis of a multi-level osteoporotic compression fracture was transferred to our institute. Lumbar spine magnetic resonance images revealed vertebral body collapse with the formation of a cavitary lesion at L1, and a chronic spinal epidural hematoma extending from L1 to L3. Because of intractable back pain, a percutaneous vertebroplasty was performed. The pain improved dramatically and follow-up magnetic resonance imaging obtained three days after the procedure showed a nearly complete resolution of the hematoma. Here, we present the rare case of a chronic spinal epidural hematoma associated with Kummell's disease and discuss the possible mechanism.

Open discectomy remains the standard method for treatment of lumbar disc herniation, but can traumatize spinal structure and leaves symptomatic epidural scarring in more than 10% of cases. The usual transforaminal approach may be associated with difficulty reaching the epidural space due to anatomical peculiarities at the L5–S1 level. The endoscopic interlaminar approach can provide a direct pathway for decompression of disc herniation at the L5–S1 level. This study aimed to evaluate the clinical results of endoscopic interlaminar lumbar discectomy at the L5–S1 level and compare the technique feasibility, safety, and efficacy under local and general anesthesia (LA and GA, respectively).
One hundred twenty-three patients with L5–S1 disc herniation underwent endoscopic interlaminar lumbar discectomy from October 2006 to June 2009 by two spine surgeons using different anesthesia preferences in two medical centers. Visual analog scale (VAS) scores for back pain and leg pain and Oswestry Disability Index (ODI) sores were recorded preoperatively, and at 3, 6, and 12 months postoperatively. Results were compared to evaluate the technique feasibility, safety, and efficacy under LA and GA.
VAS scores for back pain and leg pain and ODI revealed statistically significant improvement when they were compared with preoperative values. Mean hospital stay was statistically shorter in the LA group. Complications included one case of dural tear with rootlet injury and three cases of recurrence within 1 month who subsequently required open surgery or endoscopic interlaminar lumbar discectomy. There were no medical or infectious complications in either group.
Disc herniation at the L5–S1 level can be adequately treated endoscopically with an interlaminar approach. GA and LA are both effective for this procedure. However, LA is better than GA in our opinion.

The purpose of this study was to report a case with post-traumatic spinal epidural hematomas with abnormal neurologic findings, which is uncommon. A 40-year-old man presented at our clinic after a blunt trauma caused by a traffic accident in which he was a pedestrian. After admission, abnormal neurologic symptoms developed including loss of sensation and motor function in his left lower extremity. Magnetic resonance imaging demonstrated a spinal epidural hematoma with 40% canal stenosis at the L5-S1 level. Decompression including hematoma evacuation was done. Symptoms started to be reduced 18 days after operation. He was treated conservatively with medications and all symptoms resolved completely during admission and there were no further neurologic sequelae. Post-traumatic lumbar spinal epidural hematoma with abnormal neurologic findings is an uncommon condition that may present belatedly after trauma with significant neurologic compromise.
