BACKGROUND: Disparate outcomes in critical limb ischemia (CLI) persist between ethnicities. The contribution of modifiable factors versus intrinsic biologic differences remains unclear. Hence, we aimed to quantify the associations between ethnicity and anatomic patterns of arterial occlusive disease in CLI, adjusting for known atherosclerotic risk factors. METHODS: We performed a retrospective, single-center review of consecutive patients presenting to the vascular surgery service with CLI...

Monocytes are mononuclear cells characterized by distinct morphology and expression of CD14 and CD16 surface receptors. Classical, quiescent monocytes are positive for CD14 (lipopolysaccharide receptor) but do not express Fc gamma receptor III (CD16). Intermediate monocytes coexpress CD16 and CD14. Nonclassical monocytes with low expression of CD14 represent mature macrophage-like monocytes. Monocyte behavior in peripheral arterial disease (PAD) and during vessel wall directed treatment is not well defined...

INTRODUCTION AND OBJECTIVES: Tibioperoneal occlusive disease is one of the most difficult disease processes to successfully treat. Previous studies have attempted to address the outcomes of tibial interventions in this patient population; however, the majority of these study cohorts are composed of patients who have undergone concomitant aortoiliac or femoral procedures. Our objective was to present the outcomes of patients treated with endovascular intervention for isolated below-the-knee atherosclerotic disease causing critical limb ischemia (CLI)...

BACKGROUND: Peripheral arterial disease (PAD) is common and symptoms can be debilitating and lethal. Risk management, exercise, radiological and surgical intervention are all valuable therapies, but morbidity and mortality rates from this disease are increasing. Circulatory enhancement can be achieved using simple medical electronic devices, with claims of minimal adverse side effects. The evidence for these is variable, prompting a review of the available literature. METHODS: Embase and Medline were interrogated for full text articles in humans and written in English...

Peripheral arterial disease, particularly critical limb ischemia, is an area with urgent need for optimized therapies because, to date, vascular interventions often have limited life spans. In spite of initial encouraging technical success after femoropopliteal percutaneous transluminal angioplasty or stenting, postprocedural restenosis remains the major problem. The challenging idea behind the drug-coated balloon (DCB) concept is the biological modification of the injury response after balloon dilatation. Antiproliferative drugs administered via DCBs or drug-eluting stents are able to suppress neointimal hyperplasia, the main cause of restenosis...

BACKGROUND: External counterpulsation therapy enhances blood flow and was shown to improve endothelial function and quality of life in coronary artery disease patients. However, high pressures of up to 300 mmHg may lead to malperfusion of the ischaemic limb. To improve the clinical outcome of patients with peripheral artery disease (PAD), we adjusted external counterpulsation and developed a novel non-invasive approach termed individual shear rate therapy (ISRT). PATIENTS AND METHODS: In the present study, 14 patients with a Fontaine stage IIb and femoral-popliteal PAD underwent 30 hours of ISRT over 5 weeks...

Peripheral vascular disease (PVD) is a devastating medical problem that may lead to significant life alterations for patients, from simply limiting their daily activities to potential loss of limbs and eventual demise. Superficial femoral and popliteal arteries are significantly common locations for PVD sequelae to present itself, and owing to their length and mobile nature, treatment of these segments are quite challenging. Indications for PVD treatment include lifestyle-limiting claudication that is not responding to medical management, ischemic rest pain, nonhealing ulcers, and lower extremity gangrene...
