Sixty-eight patients with 68 femoropopliteal occlusions were entered into a randomized trial of conventional guide-wire and catheter percutaneous angioplasty versus laser thermal angioplasty. Thirty-four occlusions were randomized to conventional angioplasty and 34 to laser thermal angioplasty. After successful recanalization and balloon dilation, the patients were followed up for 1 year. Follow-up consisted of obtaining measurements of the ankle-arm indexes at 1, 3, 6, and 12 months. The increase in the mean resting ankle-arm index 1 year after conventional angioplasty (0.26) was greater than that after laser angioplasty (0.12). At 1-year follow-up, the cumulative success rate was 47% for patients treated with conventional angioplasty versus 39% for those treated with laser angioplasty. Statistical analysis showed no significant difference in clinical success between the two treatment groups.

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).
