Review of Sharp Recanalization Techniques in Central Venous Occlusions.

Benign central venous occlusions are frequently associated with long-term central venous access. Most of these occlusions can be recanalized with conventional endovascular technique. When conventional technique fails, sharp recanalization techniques (SRTs) can increase technical success.

Diagnostic Imaging.

Vascular tumors and malformations encompass a spectrum of pathology that varies widely in presentation, severity, and treatments. Although typically a clinical diagnosis, accurate classification of lesions is often challenging. Imaging plays an integral role in confirming the clinical diagnosis, determining the extent of disease and planning treatment strategies.

Combined conventional transarterial chemoembolization with Mitomycin and percutaneous ablation for unresectable hepatocellular carcinoma.

Background: Conventional transarterial chemoembolization (cTACE) has been the standard treatment for intermediate stage hepatocellular carcinoma (HCC). For early stage HCC, percutaneous ablation is a curative option. There is growing evidence to support combined therapy to improve tumor response and overall survival (OS) in patients with unresectable HCC.

Practice Patterns of Inferior Vena Cava Filter Placement and Factors That Predict Retrieval Rates: A Single-Center Institution and Review of the Literature.

Background: There is a wide variability in practice patterns on the use of inferior vena cava filters (IVCFs) among institutions, which is likely due to contrasting indication guidelines published by different professional societies. The aim of the present study is to report our healthcare system use of IVCF to: 1) determine practice patterns, 2) determine factors that may predict IVCF retrieval and 3) identify areas for improvement.

Methods: A retrospective review of 180 consecutive IVCF placement performed between July 2014 and December 2015 was conducted.

Pretreatment albumin may aid in patient selection for intrahepatic Y-90 microsphere transarterial radioembolization (TARE) for malignancies of the liver.

Background: Hepatic malignancies are common including primary malignancies and metastases. Transarterial radioembolization (TARE) is an important treatment option. We reviewed safety and efficacy of (TARE) in our patients to identify factors that may impact treatment outcomes in a heterogeneous population.

Accuracy of Noncontrast Quiescent-Interval Single-Shot Lower Extremity MR Angiography Versus CT Angiography for Diagnosis of Peripheral Artery Disease: Comparison With Digital Subtraction Angiography.

Objectives: This study sought to evaluate the image quality and diagnostic accuracy of noncontrast quiescent-interval single-shot (QISS) magnetic resonance angiography (MRA) versus iodine-contrast computed tomography angiography (CTA) in patients with peripheral artery disease (PAD), with invasive digital subtraction angiography (DSA) as the reference standard.

Background: QISS is a recently introduced noncontrast MRA technique. Although the diagnostic accuracy of QISS is reportedly similar to that of contrast-enhanced MRA, its performance compared with contrast-enhanced CTA, the most frequently used noninvasive modality for evaluation of PAD, is unknown.

Transarterial embolization of a hepatic arteriovenous malformation in an infant using Onyx: a case report and review of the differential diagnosis imaging findings.

Hepatic arteriovenous malformations are rare congenital lesions associated with significant morbidity and mortality, most commonly from high output cardiac failure. Efficient diagnosis and treatment demands an interdisciplinary approach, and the interventional radiologist plays a pivotal role in both. Imaging is important for diagnostic accuracy and treatment planning, and transcatheter embolization has become an established primary therapy.
