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.
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: 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 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).
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
Objective: To report our early experience with total endovascular repair of aortic-arch aneurysm using double chimney-grafts and present a literature overview.
Interventional management of recurrent deep vein thrombosis (DVT) may pose a more challenging scenario than the initial episode, with respect to both the technical approach and postprocedural management. These patients fall into two groups that have similarities as well as differences: those who have not undergone a previous interventional procedure and those with a history of endovenous intervention for DVT. Each group poses unique challenges to interventionists. In both groups, clinical and imaging assessment should be geared toward addressing the causes of recurrent DVT and determining the extent of venous thrombosis and/or obstruction.
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.
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.
Aims The time course of atherosclerosis burden in distinct vascular territories remains poorly understood. We longitudinally evaluated the natural history of atherosclerotic progression in two different arterial territories using high spatial resolution magnetic resonance imaging (HR-MRI), a powerful, safe, and non-invasive tool.
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.
Background—With recent advances in endovascular treatment, percutaneous endoluminal angioplasty has become particularly attractive for arterial lesions of Takayasu arteritis. However, data came from case reports or small series, and the long-term outcome has not been reported. The incidence of potential vascular complications after surgery or endovascular treatment is still to be determined.
Background—Claudication is a common and disabling symptom of peripheral artery disease that can be treated with medication, supervised exercise (SE), or stent revascularization (ST).
Background—Advanced chronic obstructive pulmonary disease causes a significant reduction in functional capacity because of dyspnea and fatigue, partially related to hypoxemia and compromised oxygen delivery. Percutaneous creation of an arteriovenous shunt may increase oxygen delivery and, hence, improve patients functional capacity.
