The significance of asymptomatic carotid bruits was evaluated in patients undergoing major vascular operative procedures. A retrospective analysis of 588 patients was performed. Ninety-two patients (15%) had unilateral carotid bruits detected on admission examination. None had had cerebrovascular symptoms. Four postoperative strokes occurred in the total group of 588 patients. All occurred in patients without bruits. There were no permanent or transient postoperative neurological deficits in the group of patients with asymptomatic unilateral carotid bruits. We can find no data to support the necessity for preoperative carotid arteriography and endarterectomy in the patient with an asymptomatic carotid bruit prior to undergoing a major operative procedure.
在接受重大血管手术的患者中评估了无症状颈动脉杂音的意义。对588例患者进行了回顾性分析。92例患者（15%）在入院检查时发现有单侧颈动脉杂音。均无脑血管症状。588例患者的整个队列中发生了4例术后中风。所有中风均发生在无杂音的患者中。无症状单侧颈动脉杂音的患者组中没有出现永久性或短暂性术后神经功能缺损。我们找不到数据支持在无症状颈动脉杂音的患者进行重大手术前进行术前颈动脉血管造影和动脉内膜切除术的必要性。
