Follow-up of 798 patients by Duplex scanning or digital venous angiography 6 months to 13 years after carotid endarterectomy revealed a recurrent stenosis rate of 3.4%. The incidence of the recurrent lesions showed a clear correlation with the operative technique: after closure of the arteriotomy directly (continuous suture) or with a vein patch (303 pat.) the recurrent stenosis rate was 4 times higher than after closure with a dacron patch (495 pat.). Our investigations indicate that recurrent stenosis and occlusions after carotid endarterectomy are largely avoidable. Sufficient length of arteriotomy (5-8 cm), dilatation of the distal internal carotid artery and lumen congruent closure of the arteriotomy with a dacron patch are the pivots of success.
在798例患者接受颈动脉内膜切除术后6个月至13年，通过双功扫描或数字静脉血管造影进行随访，发现复发狭窄率为3.4%。复发病变的发生率与手术技术有明显相关性：直接缝合（连续缝合）或用静脉补片关闭动脉切开处（303例）后的复发狭窄率比用涤纶补片关闭（495例）后的高出4倍。我们的研究表明，颈动脉内膜切除术后的复发狭窄和闭塞在很大程度上是可以避免的。动脉切开处足够的长度（5 - 8厘米）、颈内动脉远端的扩张以及用涤纶补片使动脉切开处管腔完全贴合是成功的关键。
