A total of 274 patients (mean age 67.1 +/- 8.2 years) with asymptomatic stenosis of the internal carotid artery greater than 70% was treated by desobliteration and patchplasty; 332 reconstructions were performed either uni- or bilaterally. In this group only 29% revealed a one vessel disease. Lethality within 30 days was 1.5%; the incidence of complete stroke amounted to 0.9%. In a mean follow up period of 30.8 +/- 20.2 month to lethality rate was 4.4%; 7.8% developed a completed stroke and only 3.8% were related to the operated site. The 5-year-survivalrate was 88.9% and 93.2% of this cohort was neurological free of symptoms.
共有274例（平均年龄67.1±8.2岁）无症状性颈内动脉狭窄超过70%的患者接受了血管再通和补片成形术治疗；共进行了332次单侧或双侧重建手术。该组中只有29%的患者为单支血管病变。30天内的死亡率为1.5%；完全性卒中的发生率为0.9%。平均随访期为30.8±20.2个月，死亡率为4.4%；7.8%的患者发生了完全性卒中，其中只有3.8%与手术部位有关。5年生存率为88.9%，该队列中93.2%的患者无神经症状。
