The purpose of this study to compare balloon angioplasty (PTA) vs. cutting balloon angioplasty (CB-PTA) in terms of patency and postintervention inflammation in peripheral artery disease.
Balloon Angioplasty is a minimal invasive technique for treatment of superficial femoropoliteal artery obstructions. Despite high initial success rate and an acceptably low complication rate, long-term-results are disappointing as restenosis may frequently occur. One of the hypothesis for the differences in the reported patency rates is that the amount of vessel trauma correlates directly to the prognosis (restenosis) of the treated vessel wall segment.
With the introduction of cutting balloons the problems of elastic recoil and residual stenosis might be resolved, by reduction of vessel wall trauma, vessel wall inflammation and consequently reduced neointima formation.
The promising results especially in coronary arteries led us to initiate a RCT comparing primary PTA vs. CB-PTA for treatment of femoropoliteal obstructions in patients with intermittent claudication or critical limb ischemia.

This is the first clinical research trial in which intravenous Prostaglandin E1 (PGE1 is a vasoactive hormone) will be used as supportive treatment along with the angioplasty procedure to ...
The purpose of this study is to compare the different endovascular treatment modalities for the femoropopliteal segment, and to determine technical success, efficacy and patency at mid-ter...
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 s...
The purpose of this study is to determine if it is safe and feasible to apply PRT-201 to the adventitia of arteries following successful angioplasty (PTA).
Adaptive immunity is critical in vascular remodelling following arterial injury. We hypothesized that acute changes in T cells at a percutaneous transluminal angioplasty (PTA) site could serve as an i...
Budd-Chiari syndrome (BCS) is a rare but life-threatening disease. If not treated promptly, it is almost always lethal of progressive liver failure, severe nutritional depletion, and renal failure at ...
The current state of evaluating patients with peripheral artery disease and more specifically of evaluating medical devices used for peripheral vascular intervention (PVI) remains challenging because ...
The benefits of kidney transplantation in diabetic patients with peripheral vascular disease (PVD) are unclear. While patients may have improved survival compared to dialysis, the burden of care after...
Peripheral arterial disease is a major cause of morbidity and disability and has been consistently associated with an adverse overall prognosis. Oxidative stress has been linked to vascular disease, w...
A technique utilizing a laser coupled to a catheter which is used in the dilatation of occluded blood vessels. This includes laser thermal angioplasty where the laser energy heats up a metal tip, and direct laser angioplasty where the laser energy directly ablates the occlusion. One form of the latter approach uses an EXCIMER LASER which creates microscopically precise cuts without thermal injury. When laser angioplasty is performed in combination with balloon angioplasty it is called laser-assisted balloon angioplasty (ANGIOPLASTY, BALLOON, LASER-ASSISTED).
Techniques using laser energy in combination with a balloon catheter to perform angioplasty. These procedures can take several forms including: 1, laser fiber delivering the energy while the inflated balloon centers the fiber and occludes the blood flow; 2, balloon angioplasty immediately following laser angioplasty; or 3, laser energy transmitted through angioplasty balloons that contain an internal fiber.
An ergot derivative that has been used as a cerebral vasodilator and in peripheral vascular disease. It has been suggested to ameliorate cognitive deficits in cerebrovascular disease.
Flunarizine is a selective calcium entry blocker with calmodulin binding properties and histamine H1 blocking activity. It is effective in the prophylaxis of migraine, occlusive peripheral vascular disease, vertigo of central and peripheral origin, and as an adjuvant in the therapy of epilepsy.
A beta-adrenergic agonist that causes direct relaxation of uterine and vascular smooth muscle. Its vasodilating actions are greater on the arteries supplying skeletal muscle than on those supplying skin. It is used in the treatment of peripheral vascular disease and in premature labor.
Blood is a specialized bodily fluid that delivers necessary substances to the body's cells (in animals) – such as nutrients and oxygen – and transports waste products away from those same cells. In vertebrates, it is composed of blo...
