Portal Vein Stenting for Portal Biliopathy with Jaundice.

Portal biliopathy refers to obstruction of the bile duct by dilated peri- or para-ductal collateral channels following the main portal vein occlusion from various causes. Surgical shunt operation or endoscopic treatment has been reported. Herein, we report a case of portal biliopathy that was successfully treated by interventional portal vein recanalization.

End stage renal disease caused by thromboangiitis obliterans: a case report.

Introduction: Thromboangiitis obliterans or Buerger's disease is a nonatherosclerotic, segmental, inflammatory vasculitis that is strongly associated with tobacco products and commonly affects the small- and medium-sized arteries of the upper and lower extremities. However, the disease can, rarely, involve large central or visceral arteries. We report here the case of end stage renal disease due to renal artery thrombosis caused by thromboangiitis obliterans.

Feasibility and efficacy of primary tractography during percutaneous catheter drainage.

Background: The indication of percutaneous catheter drainage (PCD) has expanded with the development of guiding modalities. Since serious complications still occur, efforts and new techniques have been continuously searched for safer PCD.

Purpose: To evaluate the feasibility and efficacy of primary tractography for establishing a safe needle pathway during PCD.

Efficacy of RECIST and mRECIST criteria as prognostic factors in patients undergoing repeated iodized oil chemoembolization of intermediate stage hepatocellular carcinoma.

Background: Given that transarterial chemoembolization (TACE) is usually a repeated procedure for treatment of hepatocellular carcinoma (HCC), repeated radiologic response assessments rather than a single time point assessment may have different clinical implications through the repeated course of TACE.

Purpose: To evaluate the efficacy of RECIST and mRECIST criteria as a survival predictor across early time points after repeated TACE of HCC.

Material And Methods: Ninety-eight patients with intermediate stage HCC received repeated iodized oil TACE.

Stent graft placement for postsurgical hemorrhage from the hepatic artery: clinical outcome and CT findings.

Purpose: To evaluate the clinical results and imaging follow-up findings of stent grafts placed for hemorrhage from hepatic arteries following surgery.

Materials And Methods: The investigation included 17 patients (14 men and 3 women) who underwent endovascular stent graft placement for hepatic arterial hemorrhage following surgery. Bleeding occurred from the common hepatic artery (n = 1; 6%), right hepatic artery (n = 1; 6%), proper hepatic artery (n = 6; 35%), and gastroduodenal artery stump (n = 9; 53%).

Anomalous unilateral single pulmonary vein mimicking pulmonary arteriovenous malformation.

Anomalies involving the pulmonary vein are so rare that most of them have been reported as a case or a series of several cases. Some of them often simulate pulmonary arteriovenous malformation (AVM), and patients undergo pulmonary angiography for embolization. Herein we report a case of anomalous unilateral single pulmonary vein that was confirmed on pulmonary angiography after initial diagnosis of pulmonary AVM on contrast medium-enhanced chest computed tomography.
