Early type II endoleak repair after endovascular therapy in Behcet's disease.

Vascular complications of Behçet's disease include occlusion of vessels and arterial aneurysm formation, which is prone to rupture. Early type II endoleak repair following an endovascular stent-graft procedure for a ruptured descending aortic aneurysm in a 31-year-old man with Behçet's disease is described. Endovascular stent-grafts provide an important alternative in complicated cases, but the possibility of endoleak should be born in mind.

Cholecystectomy-related aberrant bile duct injuries and their endoscopic treatment.

Both complete transection and accidental ligation of the main bile duct because of a cholecystectomy are the injuries that are not amenable to endoscopic treatment and require an additional surgery. Leaks resulting from the severance of an aberrant bile duct may be treated endoscopically, although such injuries are difficult to be identified, thus resulting in treatment delays. Presented here are the details and follow-up results of 7 cases of patients with postcholecystectomy aberrant bile duct injuries, which were treated by endoscopic treatment.

Percutaneous biliary intervention for primary sclerosing cholangitis in a patient with situs inversus totalis.

Situs inversus totalis is a rare condition that may not cause symptoms and often occurs concomitantly with other congenital anomalies. Special attention must be given to these patients when invasive interventions are required. There are only a few reports concerning percutaneous transhepatic biliary interventions in situs inversus totalis, but technical details were not fully explained.

Is celiac artery compression syndrome genetically inherited?: a case series from a family and review of the literature.

The median arcuate ligament is a tendinous arch joining the two medial borders of the diaphragm crura together. In 13-50% of asymptomatic subjects it is responsible for significant angiographic celiac trunk compression. The significance of median arcuate ligament-associated celiac artery compression has been a source of some controversy in the past literature, and the etiology remains unclear.
