Recanalization of 75 femoropopliteal arterial occlusions was attempted with either conventional percutaneous transluminal angioplasty (n = 28; mean occlusion length, 5.5 cm) or percutaneous laser-assisted angioplasty (PLA) (n = 47; mean occlusion length, 11.6 cm). Conventional recanalization was technically successful in 21 patients (mean occlusion length, 4.4 cm +/- 3.9) and was a technical failure in seven (mean occlusion length, 8.7 cm +/- 6.2). The technical outcome was a function of the length of the occlusion (P = .04). The PLA procedure, performed with a laser with a sapphire probe, was a technical success in 32 patients (mean length, 10.7 cm +/- 6.5) and a technical failure in 15 (mean length, 13.6 cm +/- 8.2). With PLA, the length of the occlusion did not determine the technical (P = .20) or clinical (P = .12) outcome. In patients with gangrene, PLA of occlusions longer than 5 cm failed clinically (P = .02). This PLA method appeared to be safe and allowed passage through occlusions longer than 10 cm.

D000800	Angioplasty, Balloon	Use of a balloon catheter for dilation 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 DILATION in coronary arteries, ANGIOPLASTY, BALLOON, CORONARY is available.

D001157	Arterial Occlusive Diseases	Pathological processes which result in the partial or complete obstruction of ARTERIES. They are characterized by greatly reduced or absence of blood flow through these vessels. They are also known as arterial insufficiency.

D016342	Angioplasty, Laser	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).
