[Studies of internal carotid artery anomalies]

The results of experimental and clinical studies on internal carotid artery anomalies are presented. In the experimental studies it was found that only kinking caused considerable flow disturbances in the segment above the lesion. Loops and elongation of the artery caused no such disturbances. The clinical studies have shown that internal carotid artery anomalies are found in 32.7% of the patients in whom carotid and aortic arch arteriography was performed for various reasons. In 52 patients operated on for internal carotid artery anomalies, the final diagnosis was made on the basis of arteriography. Doppler and USG examinations proved to be of little usefulness in the diagnosis of internal carotid artery anomalies. Early good result of the operation was found in 43 patients (82.6%). Two patients died (3.8%). Thirty-five patients (67.3%) came for control examination. Good remote result of the operation was found in 29 patients (82.9%).
