Laser angioplasty in the lower extremities: an early surgical experience.
From July 1988 through December 1988 laser "hot tip" angioplasties coupled with balloon dilations were performed on 95 patients at the Union Memorial and University of Maryland hospitals. The patients ranged in age from 42 to 84 years (mean, 66.4 years), and there were 61 men and 34 women in the study. Indications for the procedure included claudication in 70 (74%) and severe ischemia in 25 (26%). Noninvasive studies were performed on all patients before and after the procedure. One hundred seventeen segments were treated in 28 iliac arteries and 89 superficial femoral/popliteal arteries. No tibial arteries were treated. Fifty-two stenoses and 65 occlusions occurred. The procedures were performed percutaneously in 52 patients (55%), and open surgical technique was used in 43 patients (45%). Nine immediate failures (9.5%) and 86 successes (90.5%) were noted within 24 hours of the procedure. Follow-up ranged from 1 to 6 months with a mean of 3.2 months. Late failures within this time period occurred in 21 patients (22%). The total failure rate was 30/95 or 31.5%. Only one of the patients was made worse by a failed laser-assisted balloon angioplasty. Immediate complications consisted of formation of subcutaneous hematoma in 20 of the 52 patients having percutaneous procedures (38%) and healing difficulty in 3 of the 43 patients having open surgical procedures (7%). Hospital stay was usually 1 day longer in the latter group. No patient required surgical intervention for bleeding as a result of a vessel perforation. However, this phenomenon was noted during the course of three superficial femoral artery laser-assisted balloon angioplasties.(ABSTRACT TRUNCATED AT 250 WORDS)
