PURPOSE: To determine whether proton pump inhibitor (PPI) use increases the rate of new or worsening hepatic encephalopathy (HE) after transjugular intrahepatic portosystemic shunt (TIPS) creation. MATERIALS AND METHODS: In this retrospective study, 284 of 365 patients who underwent TIPS creation from January 1, 2005, to December 31, 2016, were analyzed (186 male, mean age 56 y, range 19-84 y).

PURPOSE: To evaluate polymerization of N-butyl cyanoacrylate (NBCA)/iodized oil mixtures for lymphatic interventions in vitro. MATERIALS AND METHODS: Polymerization times of different NBCA/iodized oil mixtures (ratios of 1:0-1:7) were investigated in a static and dynamic experimental setup (performed in a lymph flow model in a silicone tube). Eight lymphatic samples with different triglyceride (TG) concentrations (low TGs, < 50 mg/dL; medium TGs, approximately 100-400 mg/dL; high TGs, > 700 mg/dL) were investigated...

Differences in drug metabolism associated with UGT1A1 polymorphism could result in individualized local response to hepatic chemoembolization with irinotecan-eluting beads (DEBIRI) or predictable toxicities. Five patients with inoperable hepatic metastases from colorectal or anal malignancies treated with DEBIRI were assessed for UGT1A1 mutations. No difference in area under the curve (AUC) for SN38 in normal liver and tumor tissue samples was noted with variant or wild-type UBT1A1 (P = .16 and P = .05, respectively)...

PURPOSE: To investigate morphometric characteristics and differences in particulate embolization between 3 drug-coated balloons (DCBs). MATERIALS AND METHODS: Effects of 3 overlapping DCBs (IN.PACT, Ranger, and Stellarex) were assessed in 24 femoral arteries of 12 swine with 28-day follow-up. Histologic analysis of treated arterial wall site and downstream skeletal muscle and coronary band changes were assessed for evidence of emboli. Paclitaxel concentration for downstream skeletal muscle and coronary band and vessel diameters with downstream changes were also measured...

PURPOSE: To evaluate imaging-related hemorrhagic risk factors for ultrasound (US)-guided native kidney biopsy. MATERIALS AND METHODS: A retrospective review was conducted of adult patients who underwent US-guided native kidney biopsy at a single center between January 2006 and March 2016 and identified 37 of 551 patients (6.72%) with postbiopsy bleeding complications, including 11 major complications (2.00%; n = 11) and 26 minor complications (4.72%; n = 26). Ten patients with major complications and 20 with minor complications were matched with 20 control subjects each by propensity score matching based on age, needle size, number of cores, blood pressure, partial thromboplastin time, prothrombin time, platelet count, and estimated glomerular filtration rate...

PURPOSE: To evaluate the effects of endovascular denervation (EDN) on abdominal cancer pain relief. MATERIALS AND METHODS: From April 2017 to February 2018, 7 cancer patients (2 males and 5 females) were enrolled in this study. The diagnoses of the patients included 3 pancreatic cancer, 2 cervical carcinoma, 1 cholangiocarcinoma, and 1 esophageal cancer with retroperitoneum lymph nodes invasion.

Between September 2008 and August 2017, 36 patients (mean age 56 y; range, 30-89 y) underwent transvenous biopsy of suspected tumor thrombus or perivascular tumor. Intravascular biopsy was pursued because of inaccessible percutaneous access in 9 patients (25%) and as part of a planned revascularization procedure in 27 patients (75%). Histopathologic results showed malignancy in 26 patients (72%) and benign etiologies in 10 patients (28%). No patients required repeat biopsy. There were no complications related to the biopsy procedure...
