Role of Stent Grafts and Helical-Woven Bare-Metal Stents in the Superficial Femoral and Popliteal Arteries.

Peripheral vascular disease (PVD) is a devastating medical problem that may lead to significant life alterations for patients, from simply limiting their daily activities to potential loss of limbs and eventual demise. Superficial femoral and popliteal arteries are significantly common locations for PVD sequelae to present itself, and owing to their length and mobile nature, treatment of these segments are quite challenging. Indications for PVD treatment include lifestyle-limiting claudication that is not responding to medical management, ischemic rest pain, nonhealing ulcers, and lower extremity gangrene. There is a wide variety of treatment options that include medical management, interventional, and surgical techniques. Interventional techniques include plain old balloon angioplasty, cryoplasty, drug-coated balloon angioplasty, self-expanding bare-nitinol stents, self-expanding covered stents, self-expanding drug-eluding stents, and a number of atherectomy devices (ie, laser, rotational, orbital, and excisional). The scope of this article is to review indications, patient selection, and deployment techniques of Viabahn and Supera self-expanding stents.
