Percutaneous rotational atherectomy (Rotablator), a high speed (> 140,000 RPM) rotational burr was used to relieve 90-99 percent obstruction in 3 superficial femoral and 2 axillary arteries. These patients had severe claudication in respective extremities. In 4 patients, the lesion was considered to be unsuitable for balloon angioplasty and one patient underwent rotational atherectomy after failure to cross the lesion with balloon catheter. The burr size used ranged from 1.5 to 2.5 mm. After rotablation, the stenosis was reduced from 94.6 +/- 4.5 percent to 42 +/- 8.4 percent. The residual narrowing was further reduced by adjunctive balloon angioplasty to 14 +/- 5.5 percent (p < 0.001). Except for hemoglobinuria in one patient, there were no complications. All patients had good distal pulsations and were relieved of their claudication. On follow-up of 5-18 months, there has been no restenosis. Thus, our preliminary experience suggests that rotational atherectomy is safe and produces gratifying results in patients with peripheral vascular disease having lesions unsuitable for primary balloon angioplasty.
经皮旋切术(Rotablator),一种高速(>140,000转/分钟)旋转磨头,用于解除3条股浅动脉和2条腋动脉90%至99%的阻塞。这些患者各自肢体有严重的间歇性跛行。4例患者的病变被认为不适合球囊血管成形术,1例患者在球囊导管未能通过病变后接受了旋切术。使用的磨头尺寸范围为1.5至2.5毫米。旋切术后,狭窄率从94.6±4.5%降至42±8.4%。通过辅助球囊血管成形术,残余狭窄进一步降至14±5.5%(p<0.001)。除1例患者出现血红蛋白尿外,无其他并发症。所有患者远端搏动良好,间歇性跛行症状缓解。在5至18个月的随访中,未出现再狭窄。因此,我们的初步经验表明,对于患有不适合原发性球囊血管成形术病变的外周血管疾病患者,旋切术是安全的,并能产生令人满意的结果。
