PURPOSE: To better understand why interventional radiologists and gynecologists differ in their approaches to symptomatic uterine fibroids. METHODS: Conversational interviews were conducted with 26 interventional radiologists and gynecologists about their professional roles, clinical reasoning, and practice variation within and outside their specialty. Interview transcripts were systematically analyzed using NVivo 10 software (QSR International, Burlington, Massachusetts) according to grounded theory and content analysis to identify key themes and compare themes across specialties and practice environments...

PURPOSE: To compare survival outcomes of small solitary hepatocellular carcinomas (HCCs) treated with thermal ablation vs resection in the Surveillance, Epidemiology, and End Results (SEER) cohort. MATERIALS AND METHODS: SEER data (November 2014 submission) were searched for histologic diagnoses of HCC and stage T1 disease (≤ 5-cm solitary tumor without vascular invasion). Comparison was made between thermal ablation and resection as the primary treatment. Overall and disease-specific survival were compared by log-rank tests (stratified for presence of fibrosis) and Cox regression (with tumor size and presence of fibrosis covariates)...

PURPOSE: To evaluate the safety and efficacy of arteriovenous fistula (AVF) creation with a thermal resistance anastomosis device (TRAD). MATERIALS AND METHODS: From January 2014 to March 2015, 26 patients underwent ultrasound (US)-guided percutaneous creation of proximal radial artery-to-perforating vein AVFs with a TRAD that uses heat and pressure to create a fused anastomosis. Primary endpoints were fistula creation, patent fistula by Doppler US, two-needle dialysis at the prescribed rate, and device-related complications...

Kichang Han, Do Yun Lee, Man-Deuk Kim, Sak Lee, Jong Yun Won, Joon Ho Kwon, Donghoon Choi, Young-Guk Ko
PURPOSE: To investigate safety and efficacy of hybrid treatment for infected aortic and iliac aneurysms. MATERIALS AND METHODS: Between July 2007 and May 2011, hybrid treatment was performed in 6 male patients (mean age, 67.7 y; range, 57-76 y). Hybrid treatment consisted of extraanatomic bypass (EAB) and isolation of infected aneurysm with vascular plugs. Aneurysms were divided into primary and secondary infected aneurysms. Primary infected aneurysm refers to an aneurysm arising from bacterial infection of the native arterial wall; secondary infected aneurysm refers to infection involving an aneurysm that was previously treated with graft placement...
