Placement of transjugular intrahepatic portosystemic shunt (TIPS) is necessary in children with portal hypertension complicated by variceal bleeding or ascites. However, placement of adult-sized endografts may be problematic due to the smaller anatomy of pediatric patients. On the other hand, placement of fixed diameter smaller stents have the corresponding problem of not accommodating future growth of the child. We describe a novel method to create an adjustable diameter TIPS as a technical solution to these problems...

PURPOSE: Debulking strategies prior to drug-coated balloon (DCB) angioplasty were suggested to improve clinical results in femoro-popliteal lesions. Currently, there are no data regarding plaque modification with a scoring balloon with subsequent DCB-angioplasty. Recently published 6-month results of the DCB-Trak registry in patients treated with scoring-balloon angioplasty and DCB-angioplasty were promising without any safety concerns. Herein, we report the 12-month follow-up data. METHODS: In a single center registry, 29 consecutive patients with 32 femoro-popliteal lesions were treated with a scoring-balloon (VascuTrak®) and a DCB subsequently...

We aimed to illustrate diseases involving the potential space around the hepatic veins. Perivenous halo sign can be seen in patients with congestive heart failure or fluid overload. Perivenous involvement can be observed in patients with alcoholic fatty liver disease, which can be focal or diffuse. Metastasis and primary liver tumor spread can also involve this space most likely due to involvement of lymphatics around hepatic veins.

The association between immunoglobulin IgG4 and autoimmune pancreatitis was first shown in 2001. Since then many previously established fibrosclerotic diseases demonstrating synchronous or metachronous multiorgan involvement have been included within the ambit of IgG4-related disease. Diagnostic criteria have been proposed involving 1) serum IgG4 level elevated beyond 135 mg/dL, 2) IgG4+ to IgG+ plasma cell ratio >40% and >10 IgG4+ cells per high power field of biopsy sample and 3) a constellation of imaging features which involve a variety of organ systems...

PURPOSE: Primary aldosteronism (PA) is a common cause of secondary hypertension. Adrenal venous sampling (AVS) is the gold standard for assessing laterality of PA, which is of paramount importance to decide adequate treatment. AVS is a technically complicated procedure with success rates ranging between 30% and 96%. The aim of this study was to investigate the success rate of AVS over time, performed by a single interventionalist. METHODS: This was a retrospective study based on consecutive AVS procedures performed by a single operator between September 2005 and June 2016...
