Endovascular Treatment of Popliteal Artery - Balloon Angioplasty Versus Primary Stenting
1. Does primary stenting have a lower 12-month restenosis rate than PTA alone in the treatment of atherosclerotic lesions of the popliteal artery?
- Alternative hypothesis: "Primary stenting with the Edwards LifeStent is associated with a lower restenosis rate than PTA alone in patients with atherosclerotic lesions of the popliteal artery at 12 months"
- Null hypothesis: "Primary stenting with the Edwards LifeStent is not associated with a lower 12-month restenosis rate than PTA alone in patients with atherosclerotic lesions of the popliteal artery""
2. Does comparison of the two intervention groups (PTA alone, stenting) disclose differences in terms of the secondary endpoints?
3. How do the intervention methods compare in terms of safety/incidence of adverse effects?
4. What are the long-term clinical implications of the two treatment methods?

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.
Minimal invasive treatment (called "endovascular") of the arteries of the lower limb remains problematic, because recurrent disease ("restenosis") frequently leads to recurrent symptoms. A...
The Advance® 18 PTX® Balloon Catheter study is a clinical trial to study the safety and effectiveness of the Advance 18® PTX® Balloon Catheter in the treatment of lesions in the superf...
The nitinol stent has proven superior primary patency than balloon angioplasty in superficial femoral artery lesions. Recent stent design improvements focus on decreasing stent fracture ra...
The purpose of this study is to assess safety and the inhibition of restenosis of the CVI Paclitaxel-coated PTA Balloon Catheter in the treatment of de-novo occluded/stenotic or reoccluded...
To investigate the 2-year technical and clinical results of primary nitinol stent placement in comparison with percutaneous transluminal angioplasty (PTA) in the treatment of de novo lesions of the po...
The common mechanism for low access flow is intimal hyperplasia leading to stenosis within the access circuit. Balloon angioplasty (percutaneous transluminal angioplasty, PTA) remains the mainstay of ...
Drug-coated balloons (DCBs) provide a novel method to locally deliver paclitaxel into the arterial wall without the need of a chronically implanted delivery system. Following the first positive pilot ...
Radial artery spasm is one of the most commonly encountered problems during transradial interventions with a reported incidence in the range of 6-10%. Balloon-assisted tracking (BAT) of guide catheter...

Medical and Biotech [MESH] Definitions
Use of a balloon catheter for dilatation of an occluded artery. It is used in treatment of arterial occlusive diseases, including renal artery stenosis and arterial occlusions in the leg. For the specific technique of balloon dilatation in coronary arteries, ANGIOPLASTY, TRANSLUMINAL, PERCUTANEOUS CORONARY is available.
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.
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).
Dilation of an occluded coronary artery (or arteries) by means of a balloon catheter to restore myocardial blood supply.
The continuation of the femoral artery coursing through the popliteal fossa; it divides into the anterior and posterior tibial arteries.
