    Abstract:
    From January to November 1989, 31 iliac and femoro-popliteal atherosclerotic lesions were treated in 29 patients (age range: 33-80 years) by means of percutaneous laser-assisted angioplasty. The lesions were 6 iliac tubular stenoses, 6 iliac occlusions and 19 femoro-popliteal occlusions, 2-20 cm long. The laser equipment employed was in 10 cases a Cardiolase 4000 Nd:YAG "hot tip" unit, and in 21 cases a Nd:YAG "sapphire contact probe" unit. Initial success was achieved in 23/31 lesions (74%); the follow-up, by clinical examination, Doppler US, and ankle-arm pressure index performed every 4th month, showed 1-year actuarial patency of 80% for femoro-popliteal occlusion and 100% for iliac lesion, with 87% cumulative patency. Overall complication rate was 22.5%. There were 6 local complications, 4 of which were hematomas at the arterial puncture site, and 2 were performation of the superficial femoral artery, all without any clinical sequelae; one patient developed rethrombosis within 72 hours from treatment, which needed amputation after an emergency bypass. Our preliminary results show no significant improvement when compared with conventional balloon angioplasty results both in immediate success rate and in short-to-midterm patency; furthermore, laser therapy was burdened by a higher complication rate. We believe that laser angioplasty should be employed only in arterial occlusion uncrossable with angiographic guidance alone.
