Purpose: This study was designed to identify parameters on CT angiography (CTA) of type II endoleaks following endovascular aortic aneurysm repair (EVAR) for abdominal aortic aneurysm (AAA), which can be used to predict the subsequent need for reinterventions.
Purpose: To investigate the causes and results of late open surgical conversion (LOSC) after failed abdominal aortic aneurysm repair (EVAR) and to summarize our 17 years’ experience with 13 various endografts.
Purpose: This study was designed to evaluate the technical success and the early clinical outcome of patients undergoing percutaneous aspiration thrombectomy (PAT) for the treatment of arterial thromboembolism following percutaneous infrainguinal transluminal angioplasty (PTA).
Background: Benefits of 2-dimensional (2D) angiosome-oriented infrapopliteal revascularization remain controversial. The aim of this retrospective study was to clarify the effect of single tibial artery revascularization on the dorsal and plantar microcirculation of critically ischemic limbs based on skin perfusion pressure (SPP).
Over the past decade, drug-coated balloons (DCBs) have emerged as an effective treatment for atherosclerosis in multiple vascular beds. Initial attempts to deliver antirestenotic agents locally without a stent scaffold included use of infusion balloons, injection into the arterial wall, and admixing drug with contrast media (1). Each of these approaches suffered from technical limitations or unpredictable systemic drug dosing. The insight that paclitaxel can be coated on an angioplasty balloon provided an important breakthrough in local drug delivery 2. DCBs rely on 3 mechanisms related to paclitaxel’s lipophilicity. First, crystalline paclitaxel can be combined with an excipient, such as contrast media, to coat an angioplasty balloon. Second, paclitaxel stays largely bound to the excipient and balloon during advancement to the target vessel. Third, a brief (1 to 3 min) inflation of the balloon at the target vessel is sufficient for local delivery of a therapeutic dose of paclitaxel, which then resides in tissues for months (3,4). All currently available paclitaxel-coated balloons rely on a specific excipient (e.g., iopromide, shellac, urea, butyryl trihexyl citrate) and paclitaxel at doses ranging from 2.0 to 3.5 μg/mm2.
Objectives: To study the economic impact on payers and providers of the four main endovascular strategies for the treatment of infrainguinal peripheral artery disease.
Background: Endovascular approach to superficial femoral artery (SFA) disease, the most common cause of symptomatic peripheral arterial disease, remains fraught with high failure rates. Newer devices including second-generation nitinol stents, drug-coated stents, drug-coated balloons, covered stents, cryo-therapy, LASER, and directional atherectomy have shown promising results. Clinical equipoise still persists regarding the optimal selection of devices, largely attributable to the different inclusion criteria, study population, length of lesions treated, definition of “patency” and “restenosis,” and follow-up methods in the pivotal trials.
Objectives: To assess and compare the intra-arterial injection–associated discomfort of iodinated contrast media (CM) and the impact on diagnostic efficacy in diabetics with critical limb ischemia (CLI).
Background: Endovascular repair of abdominal aortic aneurysm (AAA) has recently been made a class I indication in the treatment of AAA. In comparison to the conventional open surgical treatment, endovascular AAA repair (EVAR) is associated with equivalent long-term morbidity and mortality rates. Vascular surgeons perform majority of EVAR. There are no reports for the long-term results of this intervention performed by interventional cardiologists. We present one of the first reports of periprocedural and long-term outcomes of EVAR performed by interventional cardiologists.
To quantify aortic arch geometry and in vivo cardiac-induced and respiratory-induced arch translations and arch branch angulations using three-dimensional geometric modeling techniques.
Objective: The objective of this study was to evaluate trends in outcomes of inpatient mortality, surgical complications, charges, and length of stay stratified according to open vs endovascular revascularization and amputation status in patients admitted to the hospital with diabetic foot ulcers (DFUs).
Objective: This study analyzed 30-day hospital readmissions after aortoiliac (AI) and infrainguinal (II) revascularization to further characterize readmissions and to identify modifiable targets for reducing readmission rates.
Objective: The rapid evolution of endovascular surgery has greatly expanded management options for a wide variety of vascular diseases. Endovascular therapy provides a less invasive alternative to open surgery for critically ill patients who have sustained arterial injuries. The purpose of this study was to evaluate recent trends in the management of arterial injuries in the United States with specific reference to the use of endovascular strategies and to examine the outcomes of endovascular vs open therapy for the treatment of civilian arterial traumatic injuries.
Background: Endovascular repair of peripheral arterial trauma using covered stent grafts is a minimally invasive alternative to open surgery in selected patients. Although the technical feasibility of endovascular repair has been established, there are a paucity of data regarding outcomes. The purpose of this study was to evaluate the short-term outcomes of endovascular repair in patients with peripheral arterial trauma.
Objective: The objective of this study was to evaluate early and late results of the Anaconda aortic endograft (Vascutek, Terumo, Inchinnan, Scotland) in a single-center experience.
