[Dynamics of the internal carotid artery postoperative occlusion development].
The incidence of postoperative occlusion of carotid artery is low (0.5%-0.6%) and is rarely symptomatic. The aim of this study was to analyze the dynamics of the internal carotid artery (ICA) postoperative occlusion development. During one-year period, 8 000 patients were examined at Cerebrovascular Laboratory, University Department of Neurology. Among them, 33 patients (25 male and 8 female) with postoperative ICA occlusion were detected by color Doppler. We retrospectively analyzed the dynamics of ICA occlusion development from the first postoperative follow-up. The risk factors for atherosclerosis were analyzed. In 31 of 33 patients, postoperative ICA occlusion was recorded on the first follow-up examination, 3 months of carotid endarterectomy (18 right and 15 left). In 8 patients, combined occlusion of the common and ICA was detected (4 right and 4 left). One patient developed occlusion during the first year of follow-up, and in one patient it was detected 3 years after the surgery. Eight patients had also had surgery on the contralateral ICA and showed satisfactory findings. In 19 patients, mild atherosclerotic changes were found contralaterally, 5 had moderate stenosis, and 1 patient had subtotal ICA stenosis. The early onset of postoperative ICA occlusion most likely is not caused by atherosclerosis risk factors but by perioperative complications.
