Angioplasty assisted by excimer laser was performed on 27 chronic femoropopliteal occlusions, ranging from 2 to 30 cm in length, in 26 patients. Twenty-one (78%) of the procedures were successful initially. Of these, 12 (57% [44% of the total]) remained patent at follow-up 3 months later. In seven of the nine cases of reocclusion observed after 3 months (78%) a large intimal flap resulting from the angioplasty-induced dissection could be identified in the postprocedure angiogram. The authors stress the possible importance of such an intimal flap in limiting the success of laser-assisted angioplasty of long femoropopliteal occlusions.
对26例患者的27处慢性股腘动脉闭塞病变进行了准分子激光辅助血管成形术，病变长度为2至30厘米。21例（78%）手术最初成功。其中，12例（57%[占总数的44%]）在3个月后的随访中仍保持通畅。在3个月后观察到的9例再闭塞病例中，有7例（78%）在术后血管造影中可发现血管成形术引起的夹层导致的大内膜瓣。作者强调这种内膜瓣在限制长段股腘动脉闭塞激光辅助血管成形术成功率方面可能具有的重要性。
