Presented herein is the authors’ experience gained in employing a method of prosthetic repair of the internal carotid artery in patients suffering from atherosclerotic stenosis. Special attention is paid to intraoperative factors having led to arterial prosthetic reconstruction. Also analysed are the remote results of treatment in 81 of 97 operated patients. The mean duration of follow-up amounted to 28±3 months. All the patients in the remote period were subjected to colour duplex scanning of the reconstructed zone and that of the contralateral internal carotid artery (ICA), immediately followed by assessing the neurological status. Two patients were found to have developed single transient ischaemic attacks, with their grafts remaining patent. A further three patients had developed thrombosis of the graft, with restenosis of the anastomosis zone being revealed in four patients more. All complications were symptom-free. The obtained findings showed that, taking into consideration the remote results and in certain indications, prosthetic repair of carotid arteries is an efficient method of treatment for atherosclerotic lesions of the ICA and in this relation is at least not inferior to the conventional techniques of carotid endarterectomy.

KEY WORDS: prosthetic repair, internal carotid artery.
