title: [Clinical course of restenosis after carotid endarterectomy].
abstract: Angiologic and neurologic examinations, ultrasonic dopplerography were performed in 89 patients after operation of carotid endarterectomy. Period of observation was 6-182 months after operation (61 months on the average). Positive clinical effect (absence of disorders of cerebral circulation-DCC) was achieved in 91% of cases. The frequency of both repeated transitory ischemic attacks and the strokes was 9%, the best frequency being in patients with initially asymptomatic course. It was found that the degree of restenosis directly correlated with frequency of neurologic symptom development: there were no repeated DCC in normal state of the operated artery. Meanwhile DCC frequency was less than 4% in cases with the degree of restenosis less than 60% and was equal to 15.8% in more than 60% restenosis. DCC were more frequently found in occlusion of internal carotid artery. Rather favourable course of restenosis of carotid artery was also conditioned by low content of the plaques dangerous in terms of embolism. Progression of atherosclerotic damages in other parts of extracranial arteries promoted clinical manifestation of cerebral ischemia. Moreover, negative neurologic dynamics developed in 7% of the patients with restenosis less than 60%, and in 13.8% of cases with restenosis more than 60%. The conclusion was made about efficiency of carotid endarterectomy in patients with atherosclerotic damages of carotid arteries. For prevention of repeated DCC it is recommended both to perform conservative therapy after the operation and to examine dynamically the patients using ultrasonic dopplerography beginning 6 months after the operation.
