THE ROLE OF COMPUTED TOMOGRAPHY IN ASSESSMENT OF CAROTID ARTERIES CONDITION AFTER RECONSTRUCTIVE SURGERY

Objective. To determine the role of computed tomography angiography (CTA) in imaging algorithm for the patients after reconstructive carotid surgery. Material and methods. Imaging examination results of 57 patients after reconstructive carotid surgery performed during 2015-2016 were analyzed. Ultrasound examination and CTA of brachiocephalic arteries were held. Results. According to CTA data, patients were divided in three groups. In normal (adequate) condition of carotid arteries (44 patients) lumen of arteries was homogeneous, there were no defects in the lumen. Minimal deformation of internal carotid wall contour was observed - changes localization depended on the type of operation. Changes requesting follow-up (8 cases) were characterized by defects in the lumen (narrowing less than 50%), intensification of artery angulations. Complications (5 patients) included artery thrombosis, local dissection with lumen narrowing more than 50%. According to our results, the imaging algorithm for assessment of carotid arteries after reconstructive surgery was defined. Conclusion. CTA for assessment of carotid arteries condition after surgery in early postoperative period is necessary in case of suspicion of complications and limitations of ultrasound examination.
