1.  Relining technique for continuous sac enlargement and modular disconnection secondary to endotension after endovascular aortic aneurysm repair 
Endotension is an unpredictable late complication of endovascular aortic aneurysm repair (EVAR). This case report will discuss the successful treatment of enlarged aneurysmal sac due to endotension using the relining technique. An 81-year-old male complained of nondecreasing huge aneurysm sac. He had undergone EVAR for infrarenal abdominal aortic aneurysm 7 years prior and no endoleak was found through follow-up. Initially computed tomography-guided sac aspiration was tried, but in vain, Relining using the double barrel technique and tubular endograft for modular diconnection, which was unexpectedly found in the original endograft, were performed sucessfully. During follow-up after the relining procedure, the size of aneurysm sac continued to decrease in size. The relining technique is effective mothod for treating endotension.

2.  Stent fractures after superficial femoral artery stenting 
Stent fracture is one of the major factors compromising implanted stent patency due to its consequences including in-stent restenosis, thrombosis, perforation, and migration. Stent fracture can occur from stress (extrinsic or intrinsic) and biomechanical forces at different implantation sites. We report on 2 cases of stent fractures and pertinent literature. One patient, a 75-year-old male, presented with recurrence of claudication 14 months after superficial femoral artery stenting; a femoral artery occlusion with stent fracture was found, and he underwent femoropopliteal bypass. The other patient, a 72-year-old male presented with recurrence of claudication; a stent fracture was found without femoral artery occlusion, and he was treated with additional femoral artery stenting to secure the fracture site.

3.  Pulmonary Artery Embolotherapy in a Patient with Type I Hepatopulmonary Syndrome after Liver Transplantation 
Korean Journal of Radiology  2010;11(4):485-489.
Although liver transplantation (LT) is the only effective treatment option for hepatopulmonary syndrome (HPS), the post-LT morbidity and mortality have been high for patients with severe HPS. We performed post-LT embolotherapy in a 10-year-old boy who had severe type I HPS preoperatively, but he failed to recover early from his hypoxemic symptoms after an LT. Multiple embolizations were then successfully performed on the major branches that formed the abnormal vascular structures. After the embolotherapy, the patient had symptomatic improvement and he was discharged without complications.
