[Surgical treatment of asymptomatic carotid stenosis].

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.
