Asymptomatic patients with carotid stenoses exceeding 75% have an elevated ischemic cerebrovascular event rate of 18% per year (5% strokes). Our combined perioperative stroke and death rate (1980-1990: 1123 operations) is 1.85%. Thus prophylactic surgery may be indicated in the following cases: hemodynamically significant stenoses of 75% and more, especially with marginal or reduced autoregulatory reserve, rapidly progressing lesions in medically treated patients, lesions with a high risk of embolization (ulcerations on B-scan), clear interrelation between arterial lesions and positive (asymptomatic) intracranial findings (CT, NMR, TC, USD).
颈动脉狭窄超过75%的无症状患者每年发生缺血性脑血管事件的几率高达18%（其中5%为中风）。我们的围手术期中风和死亡率（1980 - 1990年：1123例手术）为1.85%。因此，在以下情况下可能需要进行预防性手术：血流动力学上具有显著意义的75%及以上的狭窄，特别是伴有边缘性或降低的自动调节储备；接受药物治疗的患者中病变进展迅速；具有高栓塞风险的病变（B超检查发现溃疡）；动脉病变与阳性（无症状）颅内检查结果（CT、核磁共振、TC、超声）之间存在明确的相互关系。
