Background The purpose of this study was to analyze the long-term outcomes associated with interruption of incompetent perforator veins (IPV) using minimally invasive techniques as adjunctive therapies in the management of patients with chronic venous insufficiency (CVI).
Objective: To report our early experience with total endovascular repair of aortic-arch aneurysm using double chimney-grafts and present a literature overview.
The role of endovascular therapy is expanding in the treatment of acute limb ischemia (ALI). In addition to catheter-based thrombolysis, there are multiple devices which allow for clot disruption and aspiration. The Trellis catheter system provides mechanical agitation of thrombus coupled with chemical thrombolysis. We present two cases of native arterial occlusions in which the Trellis catheter was used for thrombolysis. Procedural tips and challenges associated with the use of this device in native vessels are discussed. © 2012 Wiley Periodicals, Inc.
OBJECTIVE. The purposes of this review are to examine various properties of the fluoroscopic imaging equipment used during endovascular aneurysm repair (EVAR) that can be modified to reduce radiation dose while optimizing image acquisition and display, to detail geometric aspects of EVAR intraprocedural imaging used to achieve consistently optimal EVAR results, and to describe acquisition parameters and strategies for minimizing contrast-induced nephropathy.
Critical limb ischemia (CLI) occurs as a result of progressive obstructive atherosclerosis, most closely associated with tibial and pedal artery disease. Restoration of arterial blood flow can achieve relief of rest pain and improves wound healing, and revascularization is considered more and more the first-line treatment for CLI and foot salvage.
Purpose: To evaluate angiographic diagnosis and embolotherapy of patients with enlarging abdominal aortic aneurysms and computed tomographic (CT) diagnosis of type II endoleak.
Background: Use of inferior vena cava filters (IVCFs) has become more prevalent for the prevention of venous thromboembolism in part due to their ease of deployment and retrieval. Nonthrombotic complications of IVCFs are unusual but have been described. This study characterizes this cohort of patients and elucidates their clinical outcome.
Background: To describe successful endovascular rescue of a prior fenestrated endograft repair of a thoracoabdominal aneurysm that presented with combined type I and type III endoleaks due to aortic stent migration and subsequent visceral stent dislodgement.
For decades, the common femoral artery (CFA) has been considered the most appropriate arterial access site. The rationale has been that at the end of the procedure, the CFA can be compressed against the femoral head to achieve hemostasis. During standard access, the pulse is typically palpated, and the needle is advanced to the area of the strongest pulse. Although the intention is to access the CFA by palpation, in several cases, the superficial femoral artery (SFA), the deep femoral artery (DFA), or even the external iliac artery is accidentally punctured instead.
After its first introduction by Seldinger, percutaneous vascular access through the common femoral artery (CFA) has become the most widely used route of access to the arterial system for peripheral percutaneous vascular interventions. This article discusses anatomical aspects related to CFA puncture, choosing the optimal puncture site, and methods to increase the efficacy and safety of the CFA puncture.
Iatrogenic pseudoaneurysms can occur following percutaneous cardiac and peripheral procedures. There are multiple modalities available for the treatment of pseudoaneurysms including ultrasound guided compression repair, ultrasound guided thrombin injection, or endovascular repair with covered stent placement. If these methods are not indicated or unsuccessful, patients typically require open surgical repair. We report a case of a woman with a post-procedural pseudoaneurysm with concomitant arteriovenous fistula who was treated percutaneously with the implantation of an Amplatzer vascular plug. This novel technique was safe and effective and allowed our patient to avoid the morbidity and mortality associated with surgical repair. © 2012 Wiley Periodicals, Inc.
Purpose: To evaluate the performance of a heparin-bonded, expanded polytetrafluoroethylene (ePTFE)–lined nitinol endoprosthesis in the treatment of long-segment occlusive disease of the femoropopliteal artery (FPA) and to identify factors associated with loss of patency.
The prevalence of peripheral vascular disease (PVD) is on the rise. It is estimated that the number of patients living with PVD in the United States (US) and other Western countries will reach 22 million by the year 2030. This estimate is based on a number of large-scale trials conducted in the United States and in other Western countries.1-5 The complexity of PVD and the significant comorbidities affecting those with critical limb ischemia are major limiting factors in referring patients to surgery.
Background: The objective of this study is to compare intraoperative endoleak detection by carbon dioxide digital subtraction angiography (CO2-DSA) during endovascular aortic aneurysm repair (EVAR) with standard iodinated contrast angiography (ICA).
Background: Mycotic thoracic aortic aneurysms (MTAAs) are a rare yet life-threatening disease. The current standard of care consists of surgical resection, in situ or extra-anatomic revascularization, and antibiotic therapy. Despite this treatment, mortality remains high (range, 5–40%). The endovascular repair of degenerative thoracic aortic aneurysms has been shown to be safe and effective, but its use in the treatment of MTAAs is still controversial. The purpose of this study is to review the use of endovascular repair for MTAAs
