作者对30例病人(男19、女11,41～85岁)的31条股腘动脉施行了经皮准分子激光血管成形术。所有病人均有周围血管疾病症状,血管造影均证实了病变范围及严重程度。19例作了下肢术前彩色多普勒血流图。所有病例都测定了基线踝-臂指数。术前平均踝-臂指数是0.62±0.10(0.41～0.75)。股腘动脉狭窄9例,闭塞22例。狭窄度93.5%±4.7%(85%～99%),闭塞长度3～40cm(平均10.9nm±9.5)。所用激光是308nm氯化氙脉冲准分子装置。对狭窄病变及完全闭塞血管分别采用两 The authors performed percutaneous excimer laser angioplasty on 31 femoral arteries in 30 patients (19 male, 11 female, 41-85 years old). All patients had peripheral vascular disease symptoms, angiography confirmed the extent and severity of the lesion. Nineteen patients underwent preoperative color Doppler flow imaging. Baseline ankle-brachial index was measured in all cases. The average preoperative ankle-brachial index was 0.62 ± 0.10 (0.41 ~ 0.75). 9 cases of femoral artery stenosis, occlusion in 22 cases. Stenosis of 93.5% ± 4.7% (85% to 99%), occlusion length of 3 ~ 40cm (average 10.9nm ± 9.5). The laser used is a 308 nm xenon chloride pulse excimer device. On the narrow lesions and completely occluded vessels were used two
