Critical limb ischemia (CLI) is a terminal stage of peripheral arterial disease that, in the absence of intervention, may lead to lower extremity amputation or death. Endovascular interventions have become a first-line approach to the management of CLI and have advanced considerably within the past decade. This review summarizes the types of percutaneous devices and the techniques that are available for the management of CLI and the data supporting their use. These include devices that establish and maintain vessel patency, including percutaneous transluminal angioplasty, drug-coated balloons, bare metal stents, drug-eluting stents, bioresorbable vascular scaffolds, and atherectomy; devices that provide protection from embolization; and, cell-based therapies...

INTRODUCTION AND OBJECTIVES: Cell-free DNA (cfDNA) in ST-segment elevation myocardial infarction might originate from hyperactivated leukocytes at the coronary lesion. Our aim was to investigate the relationship between cfDNA and coronary reperfusion. METHODS: We studied 116 patients treated with primary angioplasty using thrombus aspiration. Coronary (during aspiration) and peripheral (at the end of the procedure) blood samples were drawn for cfDNA, as well as high-sensitivity troponin T and myeloperoxidase quantification...

Carotid endarterectomy (CEA) remains the treatment for significant carotid stenosis and stroke prevention. Approximately 100,000 CEAs are performed in the United States every year. Randomized trials have demonstrated an advantage of patch carotid angioplasty over primary closure. Complications from patches include thrombosis, transient ischemic attack, stroke, restenosis, pseudoaneurysm (PA), and infection. PA after CEA is rare, with a reported average of 0.37% of cases. We describe an unusual case of PA after polyethylene terephthalate (PTFE) patching for CEA...

The World Health Organization announced that cardiovascular disease is the number one cause of death globally, representing 31% of all global deaths. Coronary artery disease (CAD) affects approximately 5% of the US population aged 40 years and older. With an age-adjusted prevalence of approximately 12%, peripheral artery disease (PAD) affects at least 8 to 12 million Americans. Both CAD and PAD are caused by mainly atherosclerosis, the hardening and narrowing of arteries over the years by lipid deposition in the vascular bed...

INTRODUCTION: Recurrent central venous restenosis is problematic in patients with ipsilateral arteriovenous fistula. We report our experience using a drug-eluting stent for the treatment of recurrent central vein restenosis. CASE REPORT: A 60-year-old man consulted our hospital because of recurrent swelling of his left upper limb with radial-cephalic arteriovenous fistula that originated in the distal forearm. More than 3 years prior, two bare-metal stents were placed for the obstructed lesions in the left subclavian and brachiocephalic venous lesions, and repeated balloon angioplasty for recurrent in-stent stenosis was performed approximately every 3 months...

OBJECTIVE: To assess feasibility, safety, and patient satisfaction of same-day discharge (SD) following peripheral arterial interventions. BACKGROUND: Although diagnostic angiography is routinely performed as a same-day procedure, same-day percutaneous trans-luminal angioplasty is less common. Because there is very low incidence of peri-procedural complications after 4 hr, discharge after this window is possible provided the patient is able to ambulate and has necessary social support...

OBJECTIVES: To evaluate the association of diabetes mellitus (DM) with clinical and angiographic characteristics and outcomes of patients with popliteal and infrapopliteal peripheral arterial disease (PAD) undergoing peripheral vascular intervention (PVI). BACKGROUND: Clinical features and outcomes in patients with DM and popliteal or infrapopliteal PAD undergoing PVI are not well described. METHODS: Using the data from the laser in popliteal and infrapopliteal stenosis study, we retrospectively examined the association of diabetes with clinical and angiographic characteristics and risk adjusted short- and intermediate term outcomes (all cause death, major adverse events (MAE) [composite of death, ipsilateral major amputation, or repeat revascularization]) in patients with popliteal and infrapopliteal PAD undergoing PVI for critical limb ischemia treated either with laser-assisted balloon angioplasty or balloon angioplasty alone...

Stents are ubiquitously utilized in coronary and peripheral arterial disease. Interventional nephrologists, however, place stents in the venous outflow of the arteriovenous access. Stenosis is the predominant pathology that causes access dysfunction and will ultimately lead to thrombosis if uncorrected. Angioplasty and stent deployment are the current techniques available to combat stenosis. From initial bare metal stainless steel stents, the current generations of stents used are predominately covered nitinol stents...

BACKGROUND: Intermittent claudication is pain in the legs due to muscle ischaemia associated with arterial stenosis or occlusion. Angioplasty is a technique that involves dilatation and recanalisation of a stenosed or occluded artery. OBJECTIVES: The objective of this review was to determine the effects of angioplasty of arteries in the leg when compared with non surgical therapy, or no therapy, for people with mild to moderate intermittent claudication. SEARCH METHODS: Sources searched include the Cochrane Peripheral Vascular Diseases Group's Specialized Trials Register (August 2006), the Cochrane Central Register of Controlled Trials (CENTRAL, Issue 3, 2006) and reference lists of relevant articles...

PURPOSE: Endovascular treatment of infrapopliteal peripheral arterial disease (PAD) is an established and effective treatment strategy for patients with symptomatic PAD. Increasingly, complex infrapopliteal lesions are treated with an endovascular first approach, especially in the setting of critical limb ischemia for limb salvage, avoiding major amputations which impact on mobility and quality of life. However, many complex infrapopliteal lesions involving the bifurcation of the tibial arteries remain challenging to treat due to recoil or acute dissection following angioplasty and may require stenting using specialized techniques...

BACKGROUND: Acute limb ischemia (ALI) of the lower extremity is a potentially devastating condition that requires urgent and definitive management. This challenging scenario is often treated with endovascular, open surgical, or hybrid revascularization (HyR) in an urgent basis, but the comparative effects of such therapies remain poorly defined. The purpose of this study was to compare the outcomes of endovascular, open surgical, and HyR for ALI in the contemporary era. METHODS: A large statewide cardiovascular consortium of 45 hospitals was queried for patients between January 2012 and June 2015 who underwent an endovascular, open surgical, or HyR for ALI deemed at high risk of limb loss if not treated within 24 hr (Rutherford class IIA or IIB)...

Contrast-induced encephalopathy (CIE) is a rare complication of angiography. Presently reported is the case of a patient diagnosed with CIE following peripheral angioplasty with the non-ionic contrast agent, iohexol. A 66-year-old male patient described intermittent claudication and peripheral arterial disease was suspected. Lower extremity angiography was performed, and following dilation of a 7.0x150-mm balloon, a 9.0x57-mm stent was placed in the lesioned vessel. The patient subsequently developed confusion and cortical blindness, and a seizure occurred 1 hour after the procedure...

Drug coated balloons (DCB) are becoming the standard-care treatment for peripheral arterial disease (PAD). DCB use excipients to transfer and retain anti-proliferative drugs, such as paclitaxel. Excipients thus play a vital role in the design and function of DCB, however methods to coat balloons with excipients and anti-proliferative drugs remain unknown. The goal of this study was to thus develop an approach to coat and evaluate DCB for various excipients. An air sprayer method was developed to deposit paclitaxel and various excipients onto non-coated commercially available angioplasty balloons...

Peripheral artery disease (PAD) affects more than 200 million people worldwide. Hypertension has been related to increased risk of PAD. The treatment of elevated blood pressure (BP) in these patients is indicated to lower the cardiovascular risk with a BP goal of less than 130/80mmHg. Although there is no evidence that one class of antihypertensive medication or strategy is superior for BP lowering in PAD, the use of renin-angiotensin-system (RAS) inhibitors can be effective to reduce the cardiovascular risk...
