[Treatment of carotid artery arteriosclerosis 1966 to 1976. Early and late results (author's transl)].

: Early and late results of surgery for carotid arteriosclerosis between 1966 and 1976 were reviewed in 154 patients (192 operations). The percentages of excellent and good early results were 96.7% (stage 0), 91.3% (stage I), 46.6 (stage II) and 51.6% (stage III). Overall mortality was 9.1% within the month (3.8% as neurovascular risk). In late results, out of 140 survivors, the percentages of excellent and good results were 69% in stage 0, 59.7% in stage I, 45.5% in stage II and 56.7% in stage III, the mean delay being 40.5 months. There were 3.6% cases of neurological disorders (0.7% corresponding to the side of the operated carotid artery), 7.1% of vertigo and arterial hypertension, 33 (new) deaths (23.6%) occurred after a mean 31.3 months, of which 16 resulted from some cardiovascular trouble. The cumulative survival curves parallel those of the normal population showing the protection yielded by the operation and the decrease in neurovascular risk.
