OBJECTIVE. The purpose of this study was to evaluate the clinical results of the management of gastric varices by balloon-occluded retrograde transvenous obliteration with polidocanol foam versus ethanolamine oleate.
OBJECTIVE. The purpose of this study was to determine whether phlebographic features can be used to discriminate adult from adolescent varicocele.
OBJECTIVE. Ferumoxytol is increasingly reported as an alternative to gadolinium-based contrast agents for MR angiography (MRA), particularly for patients with renal failure. This article summarizes more than 3 years of clinical experience with ferumoxytol-enhanced MRA for a range of indications and anatomic regions.
OBJECTIVE. The purpose of this article is to describe the role of imaging in the management of metastatic spine disease with percutaneous ablation and vertebral augmentation. Topics include the imaging diagnosis of spinal metastases, imaging factors related to patient selection and procedural planning, intraprocedural imaging guidance, and posttreatment imaging assessment.
OBJECTIVE. The purpose of this study is to evaluate whether chemoembolization with 1,3-bis-(2-chloroethyl)-1-nitrosourea (BCNU) is a safe and effective treatment for bulky uveal melanoma liver metastasis.
OBJECTIVE. Many radiologists are unfamiliar with the new antithrombogenic medications and how to modify patient management before nonvascular percutaneous procedures performed in a radiology department. In this article, we review the indications for use, mechanism of action, pharmacokinetics, dosing, and recommendations for periprocedural management of patients using these medications.
OBJECTIVE. The purpose of this study is to evaluate the rate of overdiagnosis of pulmonary embolism (PE) by pulmonary CT angiography (CTA) in a tertiary-care university hospital.
PURPOSE: We aimed to conduct a network meta-analysis of mixed treatments for the infrapopliteal artery occlusive disease.
PURPOSE: Despite the growing evidence in the cardiology literature that transradial approach has substantial benefits over transfemoral access, this technique is rarely used during interventions in the systemic circulation. The aim of this study was to evaluate the feasibility of transradial approach for hepatic radioembolization and to compare it with transfemoral approach.
PURPOSE: We aimed to compare the outcomes of the Endurant II (Medtronic) stent-graft used under instructions for use versus off-label in high-risk patients considered unfit for conventional surgery.
PURPOSE: We aimed to evaluate the efficiency of placing an inferior vena cava (IVC) filter through the same popliteal vein access site used for percutaneous endovenous intervention in patients with extensive lower extremity deep vein thrombosis.
Many advanced techniques have been reported in the literature for difficult Günther Tulip filter removal. This report describes a bidirectional loop-snare technique in the setting of a fibrin scar formation around the filter leg anchors. The bidirectional loop-snare technique allows for maximal axial tension and alignment for stripping fibrin scar from the filter legs, a commonly encountered complication of prolonged dwell times.
Pulmonary arteriovenous malformations (PAVMs) are vascular anomalies of the lung and carry the risk of cerebral thromboembolism, brain abscess, or pulmonary hemorrhage. We describe a 64-year-old male with hereditary hemorrhagic telangiectasia (Osler-Weber-Rendu syndrome) who presented with a five-year history of progressive effort dyspnea and a PAVM in the right upper lobe successfully treated by transcatheter embolization of feeding arteries using a new occlusion device, the ArtVentive Endoluminal Occlusion System™.
PURPOSE: Splenic artery embolization is a minimally invasive therapeutic procedure utilized in a number of disorders. Ankaferd blood stopper (ABS) is a novel hemostatic agent with a new mechanism of action independent of clotting factors. We aimed to investigate the safety and efficiency of ABS for splenic artery embolization in a sheep model.
PURPOSE: We aimed to evaluate the frequency of persistence and complication rates of pulmonary arteriovenous malformations (PAVMs) treated with Amplatzer vascular plug (AVP) or Amplatzer vascular plug type 2 (AVP2).
