Purpose: The intent of this report is to describe the technical details and rationale of endovascular septectomy using a wire saw maneuver in cases of chronic aortic dissection and associated infra-renal aortic aneurysm to allow standard endovascular abdominal aortic graft placement; preliminary clinical experience is also retrospectively reviewed.
Introduction: The use of and results with the Endurant stent-graft have been reported extensively. However, there has been little if any focus placed on performance and outcomes when a 36-mm-diameter device is used.
Introduction: Minimally invasive procedures have gained great importance among the treatments for benign prostate hyperplasia (BPH) due to their low morbidity. Prostate artery embolization has emerged as a safe and effective alternative for patients with large volume BPH, not suited for surgery.
Introduction: Visceral and renal artery aneurysms (VRAAs) are an uncommon clinical entity but carry a risk of rupture with associated morbidity and mortality. The rupture risk is particularly high when the aneurysms are large, of unfavourable morphology or in the setting of pregnancy and perioperative period. Endovascular approaches are now first line in the treatment of VRAA, but conventional techniques may be ineffective in excluding aneurysms with unfavourable anatomy such as those with wide necks or at arterial bifurcation points. The neurovascular Comaneci neck-bridging device is used to temporarily cover the neck of intracranial aneurysms without occluding forward arterial flow during endovascular coiling. We report the novel use of the Comaneci neck-bridging device for the treatment of complex peripheral VRAAs.
Purpose: Sharp recanalization of chronic venous occlusions is usually performed with targeting of wire-capture devices like loop snares or balloons. We describe sharp recanalization of chronic venous occlusions using self-expanding stents and vascular plugs.
Purpose To compare effectiveness of transarterial chemoembolization (TACE) combined with microwave ablation (MWA; TACE–MWA) with TACE alone for treating hepatocellular carcinoma (HCC) tumors <=5 cm.
Background: Radioembolization (RE) with 90yttrium (90Y) resin microspheres generally employs a sandwich technique with separate sequential administration of contrast medium (CM), followed by vehicle (e.g., glucose 5% [G5] solution), then 90Y resin microspheres (in G5), then G5, and then CM again to avoid contact of CM and microspheres under fluoroscopic guidance. This study evaluates the visualization quality and safety of a modified sandwich technique with a 50/50-mixture of CM (Imeron 300) and G5 for administration of 90Y resin microspheres.
Introduction: To assess the safety, feasibility and effectiveness of image fusion guidance with pre-procedural portal phase computed tomography with intraprocedural fluoroscopy for transjugular intrahepatic portosystemic shunt (TIPS) placement.
Purpose: Transjugular intrahepatic portosystemic shunts (TIPS) were historically placed using uncovered bare-metal stents. Current practice has now shifted toward the use of polytetrafluoroethylene (PTFE)-covered stents, given the improved primary patency seen with these stents. The aim of this study was to determine whether there is any added value, such as overall survival or stent patency, when using covered stents versus uncovered stents in TIPS placement in a large cohort.
Purpose: The aim of this study is to assess the safety, effectiveness and long-term outcome of endovascular management of arterial haemorrhage after radical prostatectomy (RP).
Purpose: Prostatic arterial embolization (PAE) has emerged as a minimally invasive alternative to TURP; however, there are limited cost comparisons reported. The purpose of this study was to compare in-hospital direct costs of elective PAE and TURP in a hospital setting.
Purpose: To compare acute pain after uterine artery embolization (UAE) with tris-acryl gelatin microspheres (TAGM) versus gelatin sponge particles (GS) for leiomyoma.
Objective: To report the early results of castor device, a kind of unibody single-branched stent graft, in the treatment of type B aortic dissection (TBAD) involving the LSA.
Purpose: Arterial injury in the hand is most often due to repetitive blunt trauma. Although not always associated with significant impairment, it may cause serious ischemic damage or considerable disability. As a cause of digital ischemia, the frequency of this disorder is widely under appreciated. This study reviews the clinical and angiographic features of this condition.
Purpose: To report a transnasal snare technique for retrograde primary jejunostomy placement after surgical gastrojejunostomy.
