The present retrospective study compared the incidence of TIA, stroke, and death in patients with asymptomatic carotid stenosis (greater than 50%) during a follow-up period of 24 to 30 months. 65 patients were operated and 193 treated medically. The incidence of death was comparable in both groups. Death in most patients was due to cardiac disease or cancer. The annual incidence of TIA and stroke was not different between the two populations. Despite the low incidence of perioperative complications (%) surgery of asymptomatic carotid stenosis cannot be recommended at the present time.
本回顾性研究比较了无症状性颈动脉狭窄（大于50%）患者在24至30个月随访期内短暂性脑缺血发作（TIA）、中风和死亡的发生率。65例患者接受了手术治疗，193例接受了药物治疗。两组的死亡率相当。大多数患者的死亡是由心脏病或癌症所致。两个人群中TIA和中风的年发生率没有差异。尽管围手术期并发症发生率较低，但目前不建议对无症状性颈动脉狭窄进行手术治疗。
