Ventriculosubgaleal shunt procedure and its long-term outcomes in premature infants with post-hemorrhagic hydrocephalus



It is well known that 10–15% of hydrocephalus cases at childhood and 40–50% in premature infants, occur following Germinal matrix hemorrhage (GMH). Such hemorrhages are reported to arise due to the rupture of germinal matrix (GM) vessels as a result of cerebral blod flow changes among infants with <1500 g birth weight and <32 weeks old. Intraventricular hemorrhage (IVH) associated with GMH leads to a disruption in the cerebrospinal fluid (CSF) and ventricular dilatation. Ventriculosubgaleal shunt (VSGS) is preferred in those hydrocephalus cases because it is a simple and rapid method, precludes the need for repetitive aspiration for evacuation of CSF, establishes a permanent decompression without causing electrolyte and nutritional losses, and aims to protect the cerebral development of newborns with GMH.

Material and method

The present study comprises 25 premature cases, subjected to VSGS and diagnosed with post-hemorrhagic hydrocephalus (PHH) arising from IVH associated with GM, and low birth weight (LBW) in the Neurosurgery Department of the Medical Faculty of Erciyes University between July 2002 and September 2006. VSGS surgery was performed on those cases, and their clinical and radiological prognoses were monitored with regard to several parameters.


Mortality and morbidity results were found to be lower than those in PPH treatment methods. While prognosis of grade 4 GMHs was poor, grades 2 and 3 GMHs displayed a much better prognosis after VSGS along with complete recovery in some hydrocephalus cases.

Introduction and objective

Currently, there is still no consensus over the optimal treatment of hydrocephalus cases occurring as a result of germinal matrix hemorrhage among premature infants with low birth weight. Therefore, this patient group, comprises the cases that are most difficult to treat in Intensive Care Units. In hydrocephalus treatment required at that period, applying VSGS prior to the placement of a permanent shunt, is reported to be beneficial. In light of this recommendation, we aim to investigate VSGS treatment in cases with post-hemorrhagic hydrocephalus and its contribution to the hydrocephalus prognoses.

Material and method

The present study comprises 25 premature cases, subjected to VSGS and diagnosed with post-hemorrhagic hydrocephalus (PHH) arising from IVH associated with GM and LBW in the Neurosurgery Department of the Medical Faculty of Erciyes University between July 2002 and September 2006. Those cases were subjected to surgery 28 times, among which, the procedure was repeated due to VSGS dysfunction in one case and because of meningitis in two cases.

GMH and hydrocephalus diagnoses of the cases were established in light of the routine ultrasonography (US) performed in the newborn unit. GMHs were studied in four grades based on the classification (Fig. 1) of Papile et al. [1].

  1. Hemorrhage is limited with the germinal matrix
  2. There is an IVH but no ventricular dilatation
  3. There is IVH associated with ventricular dilatation
  4. There is a diffuse parenchymal hemorrhage

As a result of the monitoring of the head circumferences (HC) of the cases; in cases who exhibited an enlargement of more than 2 cm and tense fontanelles along with apnea and bradycardia, VSGS operation was decided upon determination of ventricular dilatation by US. All the cases diagnosed by US were monitored by brain computed tomography.

  1. Gender
  2. Birth age (weeks)
  3. Birth weight (BW)
  4. Head circumference measurements were measured at birth, before and after VSGS, and before and after VPS.
  5. GMH were classifed based on grades.
  6. Exposure to mechanic ventilation and asphyxia were investigated since it elevates cerebral ischemic damage.
  7. VSGS and VPS timings are determined according to the clinical and radiological findings.
  8. Complications during VSGS including CSF leak from incision site, migration of catheter to the subgaleal pouch, slippage of the catheter into the ventricle, development of meningitis, and intraparenchymal and subdural hemorrhage, were investigated.
  9. Clinical status after the clinical interventions was classifed in three different groups depending on the neurological conditions of the survived cases: a good overall condition (ones with a good overall health), mild neurological sequelae (mildmotor paresias), and severe neurological deficits (e.g. inability to hold one’s head upright, sit, presence of a motor deficit as plegia, etc.). The reasons behind mortality were investigated in lost cases.
  10. The cases were monitored radiologically by computed tomography (CT); Changes in the cerebral cortices were observed on CT images taken after VSGS and VPS (Fig. 2).

The method of ventriculosubgaleal shunt

Subgaleal shunt procedure was performed after 2–3 h of fasting, under 1–2 cc local anesthesia (2% prilocaine hydrochloride) and mild sedation (1.5% sevoflurane) without intubation and by nasal oxygen support in operating room settings or intensive care unit (two cases).

Approximately 1.5 cm skin incision was used from the right corner of the anterior fontanelle (Fig. 3). Periosteum was reached. Following the determination of periosteum, subgaleal dissection was started with instruments having a blunt tip. As a result of the dissection, an area of at least 10 × 10 cm, which was located towards the temporal and parietal bones, extending to the most distant ear lobe laterally and vertex posteriorly, was reached. Thus, a large pocket was established by separating galea from the periosteum (Fig. 3(3)).

Fig. 3
Stages of the subgaleal shunt technique

The margin of the incision was pulled towards the fontanelle as to expose the dura, and the vascular structures localized in the route of the ventricular catheter to be inserted, were cauterized by bipolar cauterization (Fig 3(4)). A hole was opened by a small incision, and a ventricular catheter, approximately 3-cm long, was inserted into the right lateral ventricle (Fig. 3(6)). The catheter was fixed to the dura, cut off 5–6 cm externally, and placed into the subgaleal pouch without using a metal instrument (Fig. 3(8)). No valve was employed during the procedure (Fig. 3(9)). The patients were not allowed to lay on the right temporal surface in order to encourage subgaleal collection. Depending on the condition of the scar, sutures were removed postoperatively at 8–10 days.

  4. No increase in HC, but elevation in ventricle volume shown by imaging methods.
  5. Clinical presence of intracranial pressure rise.
  6. Persistence of hydrocephalus from prematurity to maturity.

For VPS procedure, burr hole and the same incision or a new posterior one, were used. In cases that received VPS posteriorly, the former anterior catheter was removed through a small incision on the scar. General prognosis and particularly the dependency for shunt were investigated according to the clinical monitoring of the cases that received VSGS. Windows SPSS program was used along with Chi-square and Spearman correlation tests.


The present study comprises 25 premature cases, subjected to VSGS, and diagnosed with PHH arising from IVH associated with GM and LBW in the Neurosurgery Department of the Medical Faculty of Erciyes University between July 2002 and September 2006. Seventeen (68%) of our cases were female and 8 (32%) were male. In terms of age groups, two were 25–26-week-old, eight 27–28-week-old, five 29–30-week-old, five 31–32-week-old, and again five 33–34-year-old, whereas the mean birth age was 29.2 weeks. Birth weights varied between 740 and 1,930 g (mean 1,342 ± 338 g). Based on monitoring values, VAs prior to VPS, varied between 1,900 and 4,300 g (2,434 ± 615 g) (Fig. 5).

Fig. 5
Body weights of cases at birth and before VPS surgery

The head circumferences of the cases varied from 29.5 to 39.5 cm at birth (mean 32.89 ± 2.50 cm). HCs of the cases before VSGS procedure, varied between 33.5 and 40.0 cm (mean: 37.42 ± 1.70 cm), whereas, during VPS procedure, HCs were found to be between 33 and 45 cm (mean 38.69 ± 3.27 cm).

The cases that were being monitored in the premature unit and showing abnormal increases in terms of HC, were subjected to ultrasonography (US). The cases with a detected GMH, were graded according to the classification of Papile et al. as follows: 1 with no grade, 8 grade 2, 13 grade 3, and 4 grade 4. Eight of the cases had experienced asyphyxia at birth. Among those eight cases, four demonstrated grade 4 GMH, whereas the other four exhibited grade 3 GMH.

After stabilization of the vital signs of our cases within a period of 16–80 days (mean 33.08 ± 15.4 days), VSGSs were placed. After that, VPS was performed on 15 cases at the end of a period varying between 27 and 92 days (mean: 44.53 ± 17.31 days). No intervention was applied in three cases that did not receive VPS due to resolution of the clinical profile of hydrocephalus. The three cases without shunt were observed to demonstrate no hydrocephalus recurrence. The remaining seven cases without shunt, died. Three VPS cases out of 15 did not show any VPS dysfunction, whereas six of the remaining 12 cases displayed shunt meningitis, and the other six received renewal of ventricular catheters due to shunt obstruction. Among cases with meningitis development, we removed VPS and waited until the stabilization of the CSF profile with extraventricular drainage (EVD). Three of the cases with shunt meningitis demonstrated recurrence.

Eight (32%) of the VSGS cases were found to have no adequate CSF collection in the sulgaleal pouch during monitorization. In three of those, adhesions within the subgaleal space were cleaned, and a new subgaleal pouch was created. Thus, since two of those three cases were receiving meningitis treatment, their ventricular catheters were renewed, as well. Other five cases with no collection were subjected to VPS by assuming that they have reached the adequate body weight.

Postoperatively, none of the cases were let to lie on the dissection site in order to prevent re-adhesion of subgaleal pocket and help maintenance of adequate CSF drainage. However, because of lying on the same hemisphere, an increase in the anteroposterior (occipitofrontal) diameter of the cranium was observed similar to that seen in cases with sagittal synostosis. Therefore, craniums were immobilized by placing them onto circular pads created manually from dressings and cotton. Thus, the spherical form of the cranium was maintained.

Among cases with VSGS, seven (28%) had CSF leak from the incision site, whereas one (4%) had migration of catheter from the ventricle, one had slippage of catheter into the ventricle, and two (8%) had meningitis. Meningitis cases were also the cases demonstrating CSF leakage. One case exhibited subdural hemorrhage at postoperative 15 days. In the case with a catheter migrated into the ventricle, only the catheter was removed due to arrested hydrocephalus.

Following VSGS, the patients were monitored as inpatients in the respective departments for 1–6 months and then as outpatients during 4–24 months. Seven of the cases were lost during the newborn unit care. Causes of mortality are outlined in Fig. 6. No mortality was observed at surgery.

The causes behind mortalities after VSGS procedure

As a result of the 2-year monitorization of the cases and in light of the general neurological examination results of the survivors, six cases were found to have mild neurologic sequelae, whereas the remaining six were found to exhibit severe neurologic sequelae. During follow-up, six cases with resolved hydrocephalus had normal cerebral cortex thickness along with presence of grade 2 GMH. In patients with mild neurologic deficits, ventriculomegaly appearance was still present. The cases with heavy neurologic deficits had irregular ventricle contours and loculations filled with cystic CSF (Fig. 7).

Statistical results

The results were analyzed with respect to the correlation between GMH grades and survival (χ2 = 4.33, p > 0.05, n = 25). Our study had no grade 1 case. Of the grade 2 cases, 100% survived, whereas 38.5% of grade 3 cases were lost and 61.5% were survived. 50% of grade 4 cases were lost, while 50% survived first, but lost in the following days. According to the correlation analysis (r = −0.415, p < 0.05), the survival rate was found to be reduced as the grade elevated.

The correlation between hydrocephalus prognosis and GMH grades was analyzed, as well (χ2 = 5.264, p > 0.05). While 12.5% of grade 2 cases showed an increase in ventriculomegaly, 50% showed a normal cerebral cortex devleopment. As 38.5% of grade 3 cases exhibited an increase in ventriculomegaly, the increase in cerebral cortex thickness was 15.4%. Of the grade 4 cases, 50% demonstrated ventriculomegaly, whereas none of the cases had cerebral cortex development. In the correlation analysis (r = −0.426, p = 0.034), the prognosis was observed to worsen as the grade elevated.

While 25% of cases with a body weight (BW) of 500−1,000 g were observed to survive, 77% of cases that were 1,000−1,500 g, and 87.5% of cases that were 1,500−2,000 g were found to survive, as well. No statistically significant correlation was determined between the BW and survival (r = 0.27, p < 0.05). As the BW at birth rises, survival elevates.


Currently, in hydrocephalus treatment, shunt systems that enable drainage of CSF to another body cavity in order to reduce the intracranial pressure caused by the collection of CSF fluid in the ventricle, are the most widely preferred methods. However, new treatment options are investigated because premature newborns demonstrate more complications associated with VPS systems. Premature newborns constitute the patient group that requires the most difficult care. VSGS procedure is known to be preferred in those cases due to restoration of permanent ventricular decompression without causing electrolyte and nutritional losses [2]. Treatment of hydrocephalus occurring after IVH has been tested with various methods by many clinical studies. However, although known for more than 100 years, VSGS procedure is observed to be employed at a much less rate compared with the others [3].

Why VSGS (ventriculosubgaleal shunt) ?

Despite the consideration that adequate CSF drainage might not be achieved by VSGS even in premature cases with low birth weight, having a cerabral cortex thickness below 1 cm along with large ventricles on the ultrasound image, ventriculoperitoneal shunt (VPS) was not preferred over VSGS due to the following prerequisites needed for the VPS procedure: presence of a mature immune system and an adequate absorption capacity of the abdomen, effective elimination of blood products from the CSF flow in the ventricular system, and sufficient thickness of subcutaneous tissue. During the improvement of those parameters, the most important parameter that can be monitored is body weight. Therefore, it is commonly agreed that body weight should be waited to surpass 2,000 g before attempting the procedure [2, 4]. During that period, a permanent solution with minimal damage potential is needed to protect the weakened cerebral parenchyma from the effects of elevated intracranial pressure and to prevent possible complications.

It is known that repeated ventricular taps and lumbar punctures in premature newborns, might increase the risk for meningitis. Similarly, external ventricular drainage systems expose the intraventricular environment to the exterior, and subsequently those cases with weak immune systems are subjected to infection risk. Moreover, they may lead to overdrainage problems. It is even reported that those three methods could cause metabolic disorders associated with the loss of CSF, protein, and electrolytes.

Furthermore, the subcutaneous ventricular reservoir system has been found to be an inappropriate method for premature infants without subcutaneous tissue. Because of repeated punctures from the reservoir aiming for aspiration, the skin covering the reservoir can be easily damaged. It is reported to be frequently complicated with infection and necrosis on the skin [5, 6].

Timing of VSGS practice on premature infants with hydrocephalus is a contentious issue in the literature with only two studies stating clear opinions. Willis et al. report this duration as 30 days (4.2 weeks), whereas Fulmer et al. express it as 28 days (4 weeks). In the present study, VSGS was performed after an average period of 35.04 days following birth. The average value was elevated due to poor vital signs of some patients and their care with ventilator support.

Performing VPS at an early period on premature PHH cases is reported to be associated with elevated shunt infection rates alongside high shunt obstruction rates [7]. Taylor et al. published a series of 36 cases in 2001 and advocated that VPS should be performed late on premature infants because of the need for clearance of ventricle from blood products which takes at least 5 weeks. Because VPS was applied after a mean period of 42 days on their cases and nine (25%) of the 36 cases demonstrated a shunt obstruction, they had to apply 21 revisions [8]. They did not perform any procedure during that 42 days in order to protect the white matter around the ventricle from increasing intracranial pressure. However, grade 4 premature infants may show abrupt changes in their clinical conditions, and hydrocephalus can develop very rapidly [7, 9]. Under these circumstances, early VPS procedure is recommended [2, 3, 7, 8]. Authors suggest that VPS should not be applied until the baby reaches the 2,000 g body weight, and CSF level decreases below 1,000 mg/dl [3, 8].

Similarly, Levy et al. performed VPS in PHH treatment of premature cases and reported 83% shunt obstruction, whereas Lin JP et al., McCallum et al., and Scarff et al. noted shunt obstruction rates as 89, 94, and 50%, respectively [1115]. In the present study, 24% of our cases demonstrated an obstruction at the proximal end of the VPS after the procedure and those catheters were replaced. Obstruction complication of ventriculoperitoneal shunt in PHH treatment is observed to have a lower incidence because it is performed after VSGS.

In the literature, when VSGS fails in treatment of the hydrocephalus among premature cases with LBW and PHH, VPS practice is reported on patients that are considered to reach the adequate maturity [5, 9, 10, 16]. Tubbs et al. [17] reported the VPS timing or VSGS stay length as 37.4 days, whereas Fulmer et al. advocated this length to be at least 1 month in newborns with IVH because of the need for clearence of intraventricular debris [16, 17]. In the present study, VPS was performed after a mean period of 44 days. It may appear to be late according to the literature data, however, we waited for our cases to reach the 2,000 g body weight.

In the literature, complications seen during monitorization of cases with VSGS are CSF leakage from the incision site, meningitis, migration of the catheter from the ventricle or its slippage into the ventricle, and intraparenchymal hemorrhage [5, 9]. The rate of CSF leakage from the incision site has been reported to be 16.6% by Willis et al. [9], 4.7% by Tubbs et al. [17], 5% by Fulmer et al. [5], and 32% by Sklar et al. [18]. In the present study, the rate of CSF leakage from the incision site was 29% (seven cases), which was within the upper limit of the mean value of results reported in the literature. We believe, by paying more attention to the surgical closure technique, this complication may be reduced.

The rate of infection complication associated withVSGS is reported to be 66.7% by Willis et al. [9], 5.9% by Tubbs et al. [17], 0% by Fulmer et al. [5], and 10% by Sklar et al. [18]. Rahman et al. [19] reported no infection development after carrying out VSGS and VPS procedures on 15 premature infants with PHH and a birth weight below 1,500 g. Moreover, in the absence of VSGS treatment, the infection rate after early VPS treatment in premature infants with PHH was found to be increasing from 20 to 50% by Vinchon et al. [20] and as 45.2% by Reinprecht et al. [2]. Infection rates of other methods used in PHH treatment in large series in the literature are reported to be 15.9–16.4 [21] in subcutaneous reservoir method and 10–27% in EVD method [22]. Richard et al. [23], placed Ommaya reservoir in 64 cases and reported complications (pulmonary problems, meningitis, sepsis and hemorrhage) in 30 of them, whereas noted the overall infection rate as 21.8%. In the present study, infection rate was 8%, which was consistent with the literature data on VSGS. Moreover, our result was found to be considerably lower than the infection rates of other treatment methods reported in the literature [2024].

Other complications are rarely mentioned in the literature. Development rate of a new intraparenchymal hemorrhage has been noted to be 1.1% (two cases) by Tubbs et al. and 5% (one case) by Fulmer et al. [5].

Moreover, mortality associated with shunt has been noted to be a result of that during which hemorrhage occurs because of the rupture of fragile corticomeningeal arteries and veins due to rapid intraoperative decompression in the weakly myelinized neonatal brain under pressure [5]. However, Fulmer et al. [5] and Tubbs et al. [17] noted the multifocal origin of intracerebral hemorrhage in their studies. While Fulmer et al. did not use valve in their VSGS procedures, Tubbs et al. [17] employed distal slit valve that enables one-way CSF flow to the subgaleal pouch, and suggested that intraparenchymal hemorrhage could be associated with that. Newborns subjected to VPS may present with that rare complication as a result of acute ventricular decompression [5, 17]. Moreover, Richard et al. provided fibrinolytic treatment to 17 cases in their study and reported four mortalities due to fatal diffuse hemorrhage [23]. In the present series, no intraparenchymal hemorrhage complication was observed after the VSGS procedure because no valve was inserted into the used catheters, and the wound was closed before allowing excessive CSF drainage. Moreover, one of our cases demonstrated a cerebral subdural hemorrhage that was observed 15 days after the VSGS (Fig. 8). Prior to the insertion of the ventricular catheter, because of inadequate cauterization of the dura it will pass through and the gradual venous hemorrhage in the newborn with a low intracranial pressure, formation of chronic subdural hematoma was considered. No such complication has been described in the literature.

Subdural hemorrhage, a complication

Slippage of the catheter into the ventricle or its migration from the ventricle has been reported only by Fulmer et al. [5] in one (5%) case. In the current study, similarly, one (4%) case exhibited slippage of the catheter into the ventricle, whereas in another case the entire catheter migrated into the subgaleal space. Fulmer et al. [5] removed the catheter that slipped into the ventricle and performed a VPS procedure. In our case, the catheter was removed under endoscopic guidance, and by considering the hydrocephalus arrested, no other shunt intervention was found to be necessary (Fig. 9). We carried out VPS in the other case where the catheter was migrated into the subgaleal space.

In the literature, the rate of mortality for cases with VSGS is reported to be 16% by Willis et al. [9], 9% by Tubbs et al. [17], 12% by Sklar et al. [18], and 20% by Fulmer et al. [5]. However, there is no detailed information provided on the causes of those mortalities. In the present study, mortality rate was found to be higher. The fact that grade 3 and 4 cases constituted the majority of the cases in our study may be the reason behind that. Linder et al. [25] conducted a study including 641 cases and lost 86 (13.4%) of the premature newborns with LBW, whereas 36 of the cases in their study had grades 3 and 4 IVH and 27 (75%) of those exhibited mortality. Kadri et al. performed a study in which they lost 86% of the cases with grade 3 GMH and 100% of the cases with grade 4 GMH [7].

VSGS revision has been performed in 52 (28%) of 185 cases by Tubbs et al. [17] and in 5 (25%) of 20 cases by Fulmer et al. [5]. In both series, the only reason behind revision was the adhesion development in the subgaleal pouch, however, there was no obstruction in the intraventricular catheter. Particularly those adhesion scars are reported to arise from infected debris [5, 17, 21]. In revision surgery, in cases where the catheter is not obstructed, a simple dissection on the subgaleal pouch is reported to be enough [17]. In our series, revision was applied in three cases against subgaleal adhesions. These results show consistency with those in the literature.

In terms of needing no permanent VPS, while Willis et al. [9] reported a rate of 16.6% (one case), Fulmer et al. [5], Sklar et al. [18], and Rahman et al. [19] noted a rate of 20% (four cases), 11% (seven cases), and 20% (three cases), respectively. In the current study, the rate of cases requiring VPS was 12% (three cases). Our result was consistent with the literature.

Permanent VPS is reported to be necessary in the treatment of PHH generally seen in premature infants at a rate varying between 60 and 85% [24, 2630]. While Willis et al. [9] found this rate as 83.4%, Tubbs et al. [17], Fulmer et al. [5], Sklar et al. [18], and Rahman et al. [19] reported it as 84, 75, 90, and 75%, respectively. Moreover, shunt dependency occuring after other PHH treatment methods is reported to be 64–78% following EVD and 75–88% after subcutaneous reservoir use [21, 22, 31, 32]. In the current study, shunt requirement was found to be 60%. The low rate of shunt need is due to the loss of some cases with VSGS who needed VPS during the monitorization period.

The monitoring of PHH cases after VPS is reported to demonstrate 33% shunt infection complication by Fulmer et al. [5]. In our study, shunt infection rate was 24%. Linder et al. [25] reported a mortality of 75% among cases with grades 3 and 4 GMH. Kadri et al. [7] noted the distribution of mortality rates over GMH grades as follows: 38% for grade 1, 66% for grade 2, 86% for grade 3, and 100% for grade 4. In the current study, while mortality rate among cases of grade 2 was 0%, it was 38.5% for grade 3 and 50% for grade 4 cases. Those results were not consistent with the literature. The reason behind that inconsistency is the inadequacy of daily temporary CSF drainage applied through LPs until the VPS procedure against hydrocephalus in the study of Kadir et al. along with the contribution of VSGS in prognoses of our cases. In the following controls, we lost all our grade 4 cases in compliance with the literature, whereas prognosis among our cases with grade 4 GMH, was found to be poor.

Generally, survival rate of cases with GMH and IVH is reported to be 25–75% in the literature [3335]. Kazan et al. [3] reported the mortality rate of IVH associated with GMH in premature newborns, with or without surgery, as 38%. Kadri et al. [7] monitored 126 cases and reported 70 (55.5%) losses. In the current study, when post-VPS period was also included in the monitorization, 52% (13 cases) were found to be lost during monitoring, which was a result consistent with the literature. All findings were compared with the literature in Table 1.

Table 1
Summary of results of other literature and our study


  1. Rates of infections and their complications are lower than those of other PHH treatment methods in the literature.
  2. If hydrocephalus persists when the BW exceeds 200 g in those cases, then VPS insertion is appropriate.
  3. Performing VSGS without permanent VPS in cases with grades 1 and 2 GMH, can suffice in hydrocephalus treatment.

We believe, in order to provide a better quality of life and protect the weak cerebral tissues from the detrimental effects of hydrocephalus in newborns with grades 1, 2, and 3 PHH, performing VSGS procedure would be appropriate.
