[Five year follow-up of 104 cardial artery deobliteration (author's transl)].

From December 1, 1964 to December 31, 1977, 613 patients underwent 699 operations for stenotic lesions of the internal carotid artery. One hundred and four of these cases, operated before December 31, 1972, were reevaluated at 5 years. These include 9 patients stage 0 (asymptomatic), 45 patients stage I (transitory), 8 patients stage II (progressive), 22 stage III mild (mild deficiencies), and 20 stage III severe (severe deficiencies). The overall 5 year mortality is 34% with a survival rate of 65%, steadily decreasing from 87% in the first year. There is a fundamental difference to be made between results in stages 0, I, mild-III and the other, for immediate and for 5 year mortality: 19% versus 67%. The rate of local recurrences is low: 3% of patients operated on the same side. In contrast, 11 subjects underwent a bilateral procedure. Carotidal endarteriectomy improves long term survival only moderately, mainly as a result of coronary disease. However it has an undisputable effect in diminishing neurological accidents.
