View clinical trials related to Peripheral Arterial Disease.
Filter by:Peripheral arterial disease (PAD) is a disease in which fatty build-up, or "plaque," accumulates in the peripheral arteries. People with PAD often experience leg pain while walking due to reduced blood flow to the legs. This study will use magnetic resonance imaging (MRI) techniques to examine how specific features of plaque build-up in the leg arteries affect walking ability, leg strength, and balance in people with PAD.
The purpose of this research study is to determine if the transplant of a combination of stem cells obtained from the bone marrow of the same patient will contribute to the formation of new blood vessels in the severely diseased ischemic limb (leg). In this study the safe use of this combination of stem cells and its effects on making new blood vessels will be evaluated. Limb Ischemia (LI) is a severe obstruction of the arteries which seriously decreases blood flow to the extremities (mainly feet and legs) and has progressed to the point of severe pain and even skin ulcers or sores. LI needs comprehensive treatment since the condition will not improve on its own. The overall goal of treatment is to reduce the pain and increase blood flow to improve symptoms or save the leg or feet. In many cases, current options for treatment including medications, surgery or endovascular procedures have not been successful. In the last few years, investigators have explored therapies aimed to increase blood flow to the ischemic vessels by transplanting cells that will promote the development of new vessels in the diseased leg. The study hypothesis is based on the concept that the process of formation of new blood vessels is complex and requires the participation of several types of stem cells and growth factors. The lack of any of these components will produce vessels which are immature and unable to provide appropriate blood supply to the leg. Patients eligible to participate in this study are those suffering from poor circulation or severe leg blockages, which are not candidates for surgical procedures. Once the mixture of stem cells is prepared and the patient's bone marrow is ready, cells will be transplanted into the calf muscle of the diseased leg. Clinical studies to evaluate if the transplant works and is safe will be performed up to 1 year after cell transplant.
The purpose of this study is to evaluate the safety and performance of the Xpert(TM) self-expanding stent in infrapopliteal lesions as part of an overall treatment strategy in patients undergoing percutaneous intervention for the treatment of documented chronic critical limb ischemia (CLI).
To determine the effect of three different percutaneous revascularization strategies (Balloon Cryoplasty vs. Stent Placement vs. Atherectomy) in the treatment of lifestyle limiting lower extremity claudication
The Destiny trial compares the use of bare metal stent systems with drug eluting stent systems in the treatment of infrapopliteal lesions in patients with Critical Limb Ischemia. It will be investigated whether there is a difference in 12 month angiographic patency of the stented area using the 2 different stent systems.
Peripheral venous disease occurs when a vein becomes damaged or blocked. It can occur almost anywhere in the body, but is most common in the arms and legs. This study will examine people who participated in a previous venous disease study to evaluate changes in leg veins and venous disease status over a period of 11 years.
There is increasing evidence of the linkage of type 2 diabetes with low testosterone levels in men.
Injections of concentrated bone marrow mononuclear cells into ischemic tissues will result in vasculogenesis
The objective of this study is to investigate what the value is of SET after a radiological or surgical intervention for peripheral arterial disease in the aorto-iliacal, femoro-popliteal and crural segments in comparison with a control group.
