Common femoral arterial access and arteriography in infants: Principles, pearls, and pitfalls.

Infant femoral arterial access is an essential part of interventional procedures, hemodynamic monitoring, and support of critically ill patients. Due to small luminal diameter, superficial location, mobility, and increased risk of vasospasm, dissection, and thrombosis, femoral artery access in the infant is a technically demanding procedure. The purpose of this manuscript is to describe an approach to successful common femoral arterial access and arteriography in infants including common pearls and pitfalls.

Evaluating current and recent fellows' perceptions on the interventional radiology residency: Results of a United States survey.

PURPOSE: To evaluate current and recent interventional radiology (IR) fellows' perceptions on the new integrated IR residency. MATERIALS AND METHODS: An anonymous, web-based survey was distributed to 82 current and recent IR fellows across the Unites States. The survey contained 15 questions, most of which were based on a five-point Likert scale. The survey was open for a three-week period in September 2015. The results were analyzed by two trainees and three IR attending physicians. RESULTS: Sixty-four current or recent former IR fellows completed the survey (response rate 78%). Of these 18% decided to pursue a career in IR by the end of their third year of medical school. A majority believed that the integrated IR residency will be an improved IR training pathway (62%). Based on current medical school curricula, 74% either disagreed or strongly disagreed that IR residency applicants will be ready to select such a pathway by the end of their third year of medical school. CONCLUSIONS: Most current and recent IR fellows surveyed chose IR during their final year of medical school or during residency. Most respondents believe that the integrated IR residency will be an improved IR training pathway.

Two-year outcomes of balloon-occluded retrograde transvenous obliteration of gastric varices in liver transplant recipients: A multi-institutional study.

PURPOSE: To assess the 2-year effectiveness and safety of balloon-occluded retrograde transvenous obliteration (BRTO) for gastric varices (GVs) in liver transplant recipients. MATERIALS AND METHODS: Eleven liver transplant recipients underwent consecutive BRTO for GVs at four institutions. Patients included eight (73%) men and three (27%) women with mean age of 56 years±12 (SD) (range: 26-67 years). Underlying cause of liver transplantation was hepatitis C virus (HCV)-related cirrhosis in five (45%), alcohol- and HCV-related cirrhosis in three (27%), primary biliary cirrhosis in two (18%), and alcoholic cirrhosis in one (9%). Five (45%) patients underwent BRTO for actively bleeding GVs, three (17%) for high-risk GVs, and three (17%) for augmentation of portal venous flow through obliteration of gastrorenal shunts. Mean time between liver transplantation and BRTO was 78 months (range: 0.1-276 months). Technical success, GVs obliterative rates, and immediate complications were recorded. Post-BRTO hemorrhagic, transplant, and overall survival rates were evaluated at 6, 12, and 24 months. RESULTS: All (100%) procedures were technically successful. Complete GVs obliteration was achieved in ten patients (91%). Two major complications (18%) occurred in the immediate post-procedure period. One patient developed complete portal vein thrombosis, and another patient developed consumptive coagulopathy, ultimately leading to death. No post-BRTO hemorrhagic recurrences were seen at 6, 12, or 24 months. One patient (9%) had delayed upper gastrointestinal bleeding at 34 months after the procedure which was managed conservatively. Transplant and overall survival rates were 91% at 6, 12, and 24 months. CONCLUSION: BRTO has high technical success and complete GVs obliterative rates in liver transplant recipients with few complications and high graft survival rates.
