In 10 patients with peripheral arterial disease (PAD) atherectomy was performed with the Simpson atherectomy catheter. PAD was diagnosed by clinical evaluation, oxzillography, Doppler ultrasound examination, treadmill walking, and angiography. Eight patients belonged to stage II and 2 to stage IV. Two stenoses were located in the iliac artery, and the others in the superficial femoral artery or popliteal artery or both. The treadmill walking distance before the intervention ranged from 24 to 67 m before and 105 to 115 m after the procedure (speed 2 mph; gradient 12.5%). After atherectomy, the walking distance improved by 35% to 126%. No patient in stage II perceived pain. In these patients treadmill exercise was terminated because of dyspnea. The ankle/arm ratio (Doppler ultrasound) ranged from 0.4 to 1.0 before atherectomy with a mean improvement of 0.15 afterward (stages II and IV). Control angiography within three to six months in 4 patients did not reveal any significant change at the site of the original stenosis.
对10例外周动脉疾病（PAD）患者使用Simpson旋切导管进行了旋切术。通过临床评估、血氧测定、多普勒超声检查、平板运动试验和血管造影诊断为PAD。8例患者属于Ⅱ期，2例属于Ⅳ期。2处狭窄位于髂动脉，其他狭窄位于股浅动脉或腘动脉或二者均有。干预前平板运动试验行走距离为24至67米，术后为105至115米（速度2英里/小时；坡度12.5%）。旋切术后，行走距离提高了35%至126%。Ⅱ期患者均未感到疼痛。在这些患者中，平板运动试验因呼吸困难而终止。旋切术前踝/臂比值（多普勒超声）为0.4至1.0，术后平均改善0.15（Ⅱ期和Ⅳ期）。4例患者在三至六个月内进行的对照血管造影显示，原狭窄部位无任何显著变化。
