MULTIDETECTOR COMPUTED TOMOGRAPHY IN POSTOPERATIVE ASSESSMENT OF CAROTID ARTERIES
Abstract
Rationale: Carotid endarteractomy is a surgical intervention that is performed for prevention of cerebrovascular accidents, up to 80% of them being of ischemic origin, in the presence of a marked stenosis and occlusion of carotid arteries. A detailed description of specifics of postoperative changes in carotid arteries depending on the type of surgical intervention has not been published.Aim: To evaluate internal carotid arteries in the early postoperative period by means of multidetector computed tomography (MDCT) and to match the changes detected with the type of surgical intervention.Materials and methods: In 2014, 23 patients with atherosclerotic stenoses of internal carotid arteries were assessed in the Department of Roentgenology of MONIKI. As a part of preoperative work-up, the patients underwent ultrasound examination (USE) of the neck vasculature and MDCT with bolus contrast enhancement. Postoperative monitoring also included USE and MDCT. The data obtained were matched against the type of surgical intervention.Results: After the eversion procedure (15 patients), there were 14 cases of expected (normal) postoperative changes and 1 case of changes that required a follow-up. After an open (classic) carotid endarterectomy (3 patients) there was 1 case of expected postoperative changes and 2 cases requiring a follow-up. Among 5 patients who underwent a resection of internal carotid artery and its prosthetic replacement, 2 patients had expected changes, 2 patients had changes that required a follow-up and 1 patient had a complication after surgery.Conclusion: The postoperative use of MDCT for assessment of reconstructed arteries allows for identification of various types of postoperative changes, for detection of symptoms of severe complications and borderline conditions that require subsequent targeted diagnostics and monitoring.
