PURPOSE: To report the final analysis of the safety and efficacy of portal vein (PV) recanalization (PVR) and transjugular intrahepatic portosystemic shunt (TIPS) creation (PVR-TIPS) in patients with PV thrombosis (PVT) in need of liver transplantation. MATERIALS AND METHODS: Sixty-one patients with cirrhosis and PVT underwent PVR-TIPS to improve transplantation candidacy. Median patient age was 58 years (range, 22-75 y), and median pre-TIPS Model for End-Stage Liver Disease score was 14 (range, 7-42)...

PURPOSE: To test the hypothesis that computed tomography (CT)-guided bone marrow biopsy in patients with a platelet count between 20,000/uL and 50,000/uL is safe and that preprocedure platelet transfusion is unnecessary. MATERIALS AND METHODS: This single-center retrospective study included bone marrow biopsies performed between May 2009 and May 2016. The study population included 981 patients-age range, 15-93 years; average age, 57 years; 505 (51.5%) men; and 476 (48...

PURPOSE: To use network meta-analysis (NMA) to determine the optimal endovascular strategy for management of femoropopliteal peripheral artery disease (PAD) given the lack of multiple prospective randomized trials to guide treatment decisions. MATERIALS AND METHODS: NMA is a new meta-analytic method that permits comparisons among any 2 therapies by combining results of a collection of clinical trials conducted in the same or similar patient population. NMA was used to analyze data from 15 randomized controlled trials (RCTs) and 10 prospective, multicenter, single-arm trials (combined evidence [CE] NMA) that evaluated target lesion revascularization (TLR) for 5 endovascular strategies: bare metal stent (BMS), polymer-covered metal stent (CMS), drug-eluting stent (DES), drug-coated balloon (DCB) and percutaneous transluminal angioplasty (PTA)...

The effect of uterine artery embolization (UAE) on symptomatic adenomyosis was evaluated in a systematic review and meta-analysis. Four groups were evaluated: short-term (< 12 months) pure adenomyosis, short-term adenomyosis with fibroids (combined adenomyosis), long-term (> 12 months) pure adenomyosis, and long-term combined adenomyosis. Improvement of symptoms occurred in 83.1% (872/1,049) of patients. Reported symptom reduction was 4.8% greater in the short-term combined group (P = .169) and 11.4% greater in the long-term combined group (P = ...

PURPOSE: To prospectively assess feasibility, safety, and cytoreductive effect of transarterial chemoembolization on renal cell carcinoma (RCC) using drug-eluting embolic agent (DEE) saturated with doxorubicin compared with transarterial embolization (TAE). MATERIALS AND METHODS: Between 2012 and 2015, 12 patients (male/female = 5/7, age 66 y ± 9.8) with biopsy-verified RCC eligible for nephron-sparing surgery or radical nephrectomy were recruited. Mean tumor size was 3...

Immunotherapy, specifically the use of immune checkpoint inhibitors, offers a new approach to fighting cancer. Although the results of treatment with immune checkpoint inhibition alone have been remarkable for certain cancers, these results are not universal. Preclinical and early clinical studies indicate the potential for synergistic effects when immune checkpoint inhibition is combined with immunogenic local therapies such as ablation and embolization. This review offers an overview of immunology as it relates to immune checkpoint inhibition and the possibilities for synergy when combined with interventional radiology treatments...
