[Experience in diagnosis and treatment of combined lesions of the extra- and intracranial portions of the internal carotid artery].

The treatment policy concerning patients with lesions of the extra- and intracranial portions of carotid arteries is currently uncertain. The authors share herein their experience in diagnosis and treatment of 5 patients presenting with lesions of the extracranial portions of the internal carotid artery (stenosis/occlusion/pathological tortuosity) combined with arterial aneurysms and arteriovenous malformations of the brain. Of these, two patients were operated on: the first one was primarily subjected to clipping of the cerebral aneurysm then after several months underwent a reconstructive vascular operation on the ipsilateral side (resection of the internal carotid artery with its readdressing). The second patient with subtotal stenosis of the internal carotid artery who initially underwent clipping of the ipsilateral asymptomatic aneurysm of the middle cerebral artery developed occlusion of the internal carotid artery by the second stage of treatment and was not subjected to vascular operation. There were no is-chaemic cerebral complications or lethal outcomes in the operated patients in peri- and post-operative periods at all stages of treatment.
