Iliac vein stenting is an extension of arterial stent technology. The two share some technical similarities and much of the hardware; however, the indications for and purpose of iliac vein stenting are fundamentally different from arterial practice. Pathophysiologic differences require specific modifications of techniques as well. The clinical outcome of iliac vein stenting has been surprising in some aspects, challenging long-held core concepts.
Experts share their advice on the best approach to forming a “PERT” and discuss the benefits that they can offer.
Acute arterial thromboembolism and venous thrombosis are limb-threatening and potentially life-threatening conditions. Acute arterial thrombus prohibits perfusion to affected limbs, resulting in emergent limb salvage situations.
Pseudoaneurysms are distinguished from true aneurysms in that they do not include all three layers of the arterial wall. They typically develop as a result of inflammation, infection, and traumatic or iatrogenic injury.1 In contrast, although visceral artery aneurysms (VAAs) are rare, their diagnosis has increased with broader application of cross-sectional imaging and the development of improved CT angiography (CTA).2
Pelvic venous congestion syndrome is most commonly recognized as the persistence of noncyclical chronic pelvic pain for longer than 6 months in the absence of known pelvic pathology. In the presence of pelvic varices, it is associated with a myriad of nonspecific symptoms, such as bloating, backache, dysmenorrhea, dyspareunia, bladder instability, and an irritable bowel; these are not infrequently associated with lower limb varicosities and hemorrhoids.1
Embolization techniques and technology are evolving every year. We have come a long way from flow-directed polyvinyl alcohol and pushable coils to reabsorbable materials and detachable technology with extremely high accuracy. I have been using detachable coils in addition to pushable technology in my practice for a number of years. The original reason for choosing detachable coils was their precision, which results in increased patient safety.
Despite widespread treatment of AV access stenosis with PTA, we have a limited understanding of what we are treating, why it responds to dilation, and if lesion characteristics can be used to guide treatment.
An interview with Scott O. Trerotola, MD, regarding the study of DCBs in arteriovenous fistulas.
An innovative device that aims to provide the benefits of kidney transplantation while addressing the limited number of donor organs.
Peripheral artery disease (PAD) represents an advanced stage of atherosclerotic disease with an increasing prevalence, particularly in an aging population.1 In regard to femoropopliteal disease, the most common location for occlusion is the superficial femoral artery (SFA), as it’s uniquely one of the longest and most dynamically active vessels in the body, undergoing torsion, compression, flexion, and extension from hip and knee motion. Moreover, it has been reported that blood flow patterns associated with complex vascular geometry of the femoral artery is conducive to the development of atherosclerosis. Historically, the treatment of PAD was managed by medical therapy and open surgical bypass procedures.
Objective: The aim of this study was to investigate the practice pattern of inferior vena cava (IVC) filters and to determine factors predictive of filter retrievals at a multicenter, tertiary care institution.
Background: Acute kidney injury after the administration of contrast material during endovascular procedures for peripheral arterial disease generally recovers with supportive treatment. However, long-term effects of endovascular procedures for critical limb ischemia on renal function remain to be investigated.
Purpose: To report the 12-month results of the MAJESTIC clinical study of the self-expanding Eluvia paclitaxel-eluting stent in the treatment of femoropopliteal lesions.
Purpose: To quantify the hemodynamic impact of a flared renal stent on the performance of fenestrated stent-grafts (FSGs) by analyzing flow patterns and wall shear stress–derived parameters in flared and nonflared FSGs in different physiologic scenarios.
Objective: Iliac endofibrosis is a rare condition that may result in a reduction of blood flow to the lower extremity in young, otherwise healthy individuals. The data to inform everyday clinical management are weak and therefore a Delphi consensus methodology was used to explore areas of consensus and disagreement concerning the diagnosis and management of patients with suspected iliac endofibrosis.
