Active clinical trials for "Peripheral Arterial Disease"

The aim of the study is to show the implication of platelets in vasodilation using in vivo and in vitro analysis and to compare the effects of placebo, aspirin and Clopidogrel in this interaction platelets/vessels. The effects of 7 days of each treatment will be compared in healthy subjects and patients with arteriopathy.

This is an observational study of the DABRA Laser System and other medical devices intended for endovascular treatment of peripheral artery disease.

Erectile dysfunction is highly prevalent as men grow older. Among the various causes of erectile dysfunction, it has been shown that pelvic arterial insufficiency plays a very important role. The investigators have recently developed the first imaging analytical algorithm by using the abdominal/pelvis multidetector computed tomographic (MDCT) angiography to delineate the whole arterial system supplying the penis. To establish a comprehensive, cutting-edge diagnostic and interventional therapeutic program for erectile dysfunction, the investigators therefore design this series of studies by including experts from Urology, Radiology, and Cardiology. This research project (PERFECT program) includes the following 4 sub-studies: 1) differential frequency of obstructive pelvic arterial lesions in coronary artery disease patients with and without erectile dysfunction/lower urinary tract symptoms (LUTS), 2) differential frequency of obstructive pelvic arterial lesions in patients with vascular risk factors and with or without erectile dysfunction/LUTS, 3) safety, feasibility, and efficacy of comprehensive pelvic angioplasty (with various interventional strategies/instruments) for patients with erectile dysfunction/LUTS and pelvic obstructive arterial disease: proof-of-concept study; and 4) efficacy and safety of comprehensive pelvic angioplasty (with various interventional strategies/instruments) for patients with erectile dysfunction/LUTS and pelvic obstructive arterial disease: a randomized controlled trial.

To investigate the efficacy of the administration of JVS-100 delivered via direct intramuscular injections on a 3 month and 6 month composite endpoint of wound progression, healing and limb loss in patients with severe peripheral arterial disease with non-healing chronic wounds who undergo an open bypass grafting or endovascular procedure for treatment of infrapopliteal disease and are dosed within 12 days and 3 months following the procedure.

The prevalence of significant and complex obstructive coronary artery disease (CAD) is high in patients who have low extremity artery disease (LEAD). Long-term prognosis of LEAD undergoing percutaneous transluminal angioplasty (PTA) remains poor and CAD is an independent predictor of total mortality after PTA. This prospective randomized controlled trial will evaluate the prognostic effects of routine versus selective coronary angiography before PTA for LEAD and elucidate the potential mechanism.

Sildenafil has shown potential effects both on vasodilator mechanisms and as an inhibitor of the NO/GMPc Pain activation. The investigators aim at estimating the benefit of sildenafil in term of morbi-mortality in patients with arterial claudication on a multicenter prospective double blind study.

The purpose of the study is to determine the effects of Prevena therapy on decreasing groin surgical site infections in patients who are obese and /or diabetic having vascular surgery.

This is a prospective, single-center study. The patients with peripheral arterial disease who underwent abdominal aortograms with runoff (which are arteriograms of the lower abdominal aorta and arteries in the legs) and Intravascular Ultrasound after stent deployment will be enrolled in the study. All patients who participated in the study will be treated according to standard of care. HYPOTHESIS The higher degree of plaque burden on landing zone has an effect on restenosis on peripheral artery intervention. SPECIFIC AIMS To determine intravascular ultrasound parameters of stent deployment and outcomes of Femoro-popliteal Disease To determine clinical risk factors and outcomes of Femoro-popliteal Disease To obtain data that will eventually support development of a predictive model for ISR in Femoro-popliteal Disease METHODOLOGY Visit 1: After consent is given The subject will receive standard follow-up care. A member of the research team will collect information such as the subject's age, sex, ethnicity, and medical information from the subject's medical record. Visits 2-5: 1 day after enrollment, and at months 3 (+- 2 weeks), 6 (+- 2 weeks), and 12 (+- 2 weeks) The subject will complete standard follow-up appointment at TTUHSC. This may include a Doppler ultrasound. A member of the research team will record information such as medications, ultrasounds, and need for additional care related to the subject's stent. The subject will complete the questionnaire on leg pain and mobility.

After endovascular treatment (EVT) for peripheral artery disease (PAD), dual antiplatelet therapy (DAAT) of aspirin (ASA) and clopidogrel are currently drug of choice to prevent occlusion. Anplone SR®, controlled-released Sarpogrelate hydrochloride, has been introduced as an anti-platelet agent for the drug of PAD. The aim of this study was to compare the efficacy and safety of Anplone + aspirin and clopidogrel + aspirin in patients who underwent EVT for femoro-popliteal occlusive disease.

To evaluate the safety and efficacy of the Paclitaxel Releasing Peripheral Balloon Dilatation Catheter (LEGFLOW) compared to the PTA catheter (AMPHIRION DEEP) in treatment of stenosis or occlusion in below the knee artery.
