Percutaneous atherectomy--early experience in Sheffield.
Percutaneous transluminal angioplasty (PTA) of arterial stenoses is a well-established and relatively safe technique in the treatment of peripheral and coronary vascular disease. Recurrence, however, remains a problem. The 'atherectomy' catheter is a new device to provide lumen enlargement by the mechanical removal of atheroma. In Sheffield, 14 lesions in the femoral arteries have been treated by atherectomy, with a reduction in mean diameter stenosis from 88% to 15%. There were no complications. Follow-up ranges from 3 to 15 months, with a mean of 9 months. There has been only one recurrence. It can be used in calcified lesions and may prove to be most useful in the treatment of tough lesions. Further experience and follow-up is necessary, however, to determine whether it has any advantage over balloon dilatation.
