In a group of 26 patients percutaneous transluminal (balloon) angioplasty (PTA) and stents (Wallstents) were applied and in another 26 matched patients PTA alone was used as primary treatment for femoropopliteal occlusions of 3 cm or longer. Five patients with stents showed early thrombosis necessitating catheter thrombolysis and/or thrombus aspiration. Ten patients had recurrent stenoses within 12 months, mostly due to neointimal hyperplasia. Following three late catheter reinterventions, a cumulative secondary patency rate of 69% was achieved after 12 months. The group of patients treated by PTA alone showed a 12 months patency rate of 65% without reinterventions. In 8 other patients, stents were inserted for recurrent obstructive or PTA-resistant lesions, and similar results as with the stents above were obtained. Thus, these stents do not improve primary results of PTA in femoropopliteal occlusions but may be useful secondarily after unsuccessful PTA.
在一组26例患者中应用了经皮腔内（球囊）血管成形术（PTA）和支架（Wallstents），另外26例匹配的患者仅采用PTA作为3 cm或更长的股腘动脉闭塞的主要治疗方法。5例置入支架的患者出现早期血栓形成，需要进行导管溶栓和/或血栓抽吸。10例患者在12个月内出现复发性狭窄，主要原因是内膜增生。经过3次晚期导管再干预后，12个月时累积二级通畅率达到69%。单纯接受PTA治疗的患者组在未进行再干预的情况下12个月通畅率为65%。在另外8例患者中，因复发性阻塞性病变或对PTA耐药的病变而置入支架，获得了与上述支架相似的结果。因此，这些支架并不能改善股腘动脉闭塞PTA的初始效果，但在PTA失败后可能具有次要作用。
