[Surgical treatment of pathologic twisting of the internal carotid arteries]

A total of 5182 carotid angiograms were reviewed. Abnormal bending of the internal carotid artery was detected in 310 (16.4%) cases. Forty-seven such cases were analysed. Twenty-five operations were performed, including the resection with end-to-end anastomosis (8), the resection with redressing and implantation into the former opening on the common carotid artery for loop formation (6) or S-bending (7). In one case of C-bending in the internal and external carotid arteries, the kinking was eliminated by means of a resection of a part of the common carotid artery. Indications for surgery are specified with reference to the kinking variant. Optimum types of reconstructions are proposed. There were no fatal outcomes. Seventeen patients were followed up for up to 5 years. The results of surgical treatment were fairly good.
