Filter by:The objective of the present study was to evaluate the prognostic impact of prolonged dual antiplatelet therapy (DAPT) with acetylsalicylic acid plus clopidogrel on the incidence of major adverse cardiovascular events and major adverse limb events after percutaneous lower extremity revascularization in patients with lower extremity peripheral arterial disease (LE-PAD).
Peripheral artery disease (PAD) is highly prevalent. It occurs most often in the lower extremities. Symptoms include intermittent claudication, ischemic pain, ulceration and necrosis. Amputation may be necessary in severe cases. PAD is also an indicator of future cerebrovascular and cardiovascular events. Diabetes mellitus (DM) is one of the major risk factors of PAD. Approximately 5% to 10% of diabetic patients have had foot ulceration, and 1% have undergone amputation. Other risk factors include smoking, old age, male gender, hypertension, dyslipidemia, hyperhomocysteinemia and renal insufficiency. Ankle-brachial index (ABI) is the most popular tool used to screen PAD. Doppler-derived ankle and brachial systolic pressure is obtained. If the ratio is abnormal, further confirmation studies will necessary. Although ABI is recommended as one of the screening tests for diabetic complications in guidelines, its utility is limited in calcified non-compressible vessels, which are common in DM and renal failure patients. Digital infrared thermal imaging (DITI) is used to detect surface temperature because objects of absolute temperatures higher than zero would radiate electromagnetic waves of certain wave lengths according to Plank's law. DITI examination is non-invasive, non-contact and fast. Theoretically, temperature of the perfusion area of the occlusive arteries will decrease. Investigators will analyze DITI of PAD, and observe the relationship between DITI, ABI and vascular duplex examination. The dynamic change of DITI before and after percutaneous transluminal angioplasty of PAD will also be observed. Investigators would like to evaluate the possibility of the clinical application of DITI for PAD screening.
The endovascular therapy prevailed in nearly all regions of peripheral artery disease over open surgery techniques. However, in treatment of the common femoral artery vascular surgery is still the gold standard of therapy. One-year patency rates are between 90% and 95%. Today, only in selected cases an endovascular procedure for common femoral artery diseases is recommended. The primary objective of this study is to compare the performance of directional atherectomy and drug-coated balloon angioplasty over vascular surgery in common femoral artery lesions in a prospective, multi-center, randomized clinical trial.
This is a randomized, open-label, single & multiple-dose, parallel study to investigate the effect of cilostazol on the disposition of simvastatin & pravastatin in healthy male volunteers
The measurement of limb skeletal muscle perfusion and perfusion reserve during exercise is an approach that can assess the total impact of the complex pathophysiologic processes in patients with limb ischemia, particularly in those with diabetes in whom distal arterial disease and abnormal microvascular functional responses are common. This trial is designed to: (a) optimize methods for assessment of limb perfusion at rest and during stress using contrast-enhanced ultrasound (normal subjects) and a microbubble contrast agent that is able to provide non-linear signal without destruction at medium acoustic pressures, and (b) to test whether perfusion imaging provides incremental information on the severity of disease in patients with peripheral artery disease.
The purpose of this study is to evaluate the effectiveness of negative pressure incision management system (Prevena™ Incision Management System (PIMS) or ActiVAC® with the Prevena™ Dressings (Peel and Place™ or Customizable™), KCI) in the prevention of wound complications including surgical site infection (SSI) and non-infectious complications in patients undergoing vascular surgery with groin incisions.
This is a prospective, non-randomized post market surveillance registry designed to document the clinical Performance in Routine clinical practice of the POLARIS Peripheral Vascular Self Expanding Stent System
The aim of this study is to compare in patients with critical limb ischemia the efficacy of angioplasty with different paclitaxel-eluting balloon devices for below-the-knee lesions in terms of restenosis.
1. The prevalence of significant and complex obstructive coronary artery disease (CAD) is high in patients who have low extremity artery disease (LEAD). 2. Long-term prognosis of LEAD undergoing percutaneous transluminal angioplasty (PTA) remains poor and CAD is an independent predictor of total mortality after PTA. 3. 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.
In patients with critical limb ischemia (CLI) and foot ulcers wound healing is an important goal which can normally only be achieved after sufficient treatment of the underlying ischemia (revascularization either by an operation, e. g. bypass, or a catheter intervention). After successful revascularization everything should be done to improve wound healing because this regularly takes weeks up to several months. One possibility to speed up healing could be treatment with the VADOplex device which delivers an automatic intermittent painless compression of the sole of the foot thereby increasing perfusion of the leg. This system can be easily operated by patients themselves and at home. Our goal is to prove that the VADOPlex system accelerates healing up and improves quality of life.
