PURPOSE: To evaluate safety and efficacy of percutaneous hepatic microwave (MW) ablation performed near the heart. MATERIALS AND METHODS: This study reviewed 118 consecutive peripheral (ablation zone margins within 5 mm of liver capsule) percutaneous MW hepatic ablations performed between June 2010 and August 2015. Ablation zones of 27 tumors (22.8%) extended to ≤ 5 mm from myocardium, and these ablations comprised the study group; the remaining ablations formed the control group...

PURPOSE: To investigate whether accessory vein embolization (AVE) improves long-term performance of salvaged nonmaturing arteriovenous fistulae (AVFs). MATERIALS AND METHODS: This retrospective review included 72 patients who underwent percutaneous balloon angioplasty for salvage of nonmaturing AVFs between 2008 and 2014. AVE was performed on 32 patients between 2008 and 2011 (mean age, 59 y [range, 33-85 y]; men, n = 21; women, n = 11; upper arm, n = 17; forearm, n = 15), whereas the procedure was not performed on 40 patients after 2011 (mean age, 62 y [range, 28-85 y]; men, n = 26; women, n = 14; upper arm, n = 26; forearm, n = 14)...

PURPOSE: To investigate whether an autologous intraparenchymal blood patch (IPB) reduces the rate of pneumothorax-related complications associated with computed tomography (CT)-guided lung biopsies. MATERIALS AND METHODS: This study included 834 patients: 482 who received an IPB and 352 who did not. Retrospective review was performed of all CT-guided lung biopsies performed at a single institution between August 2006 and September 2013. Patients were excluded if no aerated lung was crossed...

PURPOSE: To evaluate clinical success and time to resolution of intranodal lymphangiography (INL) alone or with thoracic duct embolization (TDE) or thoracic duct disruption (TDD) based on initial effusion volume for postsurgical chylothorax. MATERIALS AND METHODS: Retrospective review was performed of 57 patients (mean age 63 y; 65% male) undergoing INL alone or in conjunction with other percutaneous techniques for postsurgical chylous effusions. INL alone was performed when chylothorax output was ≤ 500 mL/d and no leak was identified during fluoroscopy...

PURPOSE: Transient elastography (TE) is routinely used for noninvasive staging of hepatic fibrosis. The objective of the present study was to investigate the role of TE (FibroScan) in determining changes in liver congestion in patients with Budd-Chiari syndrome (BCS) treated by endovascular interventions and determine the effects of pretreatment Meta-analysis of Histological Data in Viral Hepatitis (METAVIR) fibrosis score on posttreatment liver stiffness (LS). MATERIALS AND METHODS: Twenty-five patients undergoing endovascular procedures for treatment of BCS underwent TE immediately before and within 24 hours after the procedure...

In the high-volume and increasingly complex world of image-guided therapy and medical imaging, awareness of the potential risks secondary to occupational radiation exposure in medical professionals needs greater focus. One of these risks is radiation-induced cataracts, a recently recognized entity, which may impact the physician's professional proficiency, quality of life, and career span. This review article aims to explain the pathogenesis of radiation-induced cataracts, exploring emerging evidence regarding their development...

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...
