Laser angioplasty with direct argon laser light, combined with a special centering balloon (Lastac system) was performed in 12 patients with a single superficial femoral artery occlusion. The mean length of the occlusion was 5.4 +/- 2.15 cm with a mean duration of occlusion of 7.8 +/- 5.9 months. Initial angiographic success was obtained in 9/12 procedures. Reason of failure was perforation in 1 patient and impossibility to pass the stenosis due to calcifications in 2 patients. Early rethrombosis in 1 patient reduced the primary success rate to 8/12 procedures. Peripheral emboli occurred in 2 patients, both successfully treated by thrombolysis or surgery. Of the 8 recanalized arteries, all remained patent with a mean follow-up of 7.1 +/- 0.68 months. It remains to be determined on larger series whether the Lastac system offers substantial advantages over other, less expensive systems of laser angioplasty.
