361例颈动脉内膜切除术后24个月内再狭窄发生率为3.6%。在再狭窄组中，患者往往比整个组年轻。高血压和高脂血症的发生率也更高。再狭窄复发时间为5~24个月，平均12.5个月。找不到手术技术原因。再狭窄归因于快速、旺盛的肌内膜增殖。这一过程在组织学上与动脉粥样硬化斑块不同，动脉粥样硬化斑块是导致晚期再狭窄的原因。对于这组纤维肌内膜增生型病变的患者，再次手术是困难的，而且很少与患者的体征和症状的改善有关。
Restenosis within 24 months of carotid endarterectomy was discovered in 3.6% of 361 operations. The patients in this group of restenosis tended to be younger than the overall group. Hypertension and hyperlipidemia were also more frequent. Restenosis recurred within an average of 12.5 months of the first operation, with a range from five to 24 months. No surgical technical causes could be found. Restenosis is attributed to rapid, exuberant myointimal proliferation. This process is histologically distinct from the atherosclerotic plaque which is the cause of late restenosis. Reoperation on this group of patients with the fibrous myointimal proliferative type of lesion was difficult and was infrequently associated with improvement in the patients' signs and symptoms.
