The present study was aimed at retrospectively analysing the results of examination and open surgical treatment of patients diagnosed with extracranial aneurysms of carotid arteries.

Patients and methods. We analysed the results of examination and outcomes of surgical treatment in a total of 11 patients (6 men and 5 women) presenting with an aneurysm of the extracranial portion of the carotid artery and undergoing treatment at the Department of Vascular and CAD Surgery of the Moscow Regional Research Clinical Institute from 2005 to 2016. The mean age of the patients amounted to 56.5±13.9 years (ranging from 33 to 73 years). The diagnosis of an aneurysm was made based upon the findings of duplex scanning with colour mapping (DS+CM), four patients were additionally subjected to computed tomography (CT) and one to magnetic resonance tomography (MRT). 8 aneurysms turned out to be true aneurysms and 3 appeared to be pseudoaneurysms. 8 aneurysms were localized in the internal carotid artery (ICA) and 3 – in the common carotid artery (CCA).

Results. Eight cases were treated by resection of the aneurysm followed by prosthetic repair (5 with an autovenous graft and 3 with a synthetic graft), a further two cases were managed by resection of the aneurysm and an “end-to-end” anastomosis made, and in one case a false aneurysm was removed, with the arterial defect sutured. The check-up examinations were carried out at 2 and 6 months of the postoperative period. Neither lethal outcomes nor acute cerebral circulation impairments (ACCIs) were registered within the time frame the follow up period. Two patients were found to suffer from cranial nerve injury having disappeared during follow-up.

Conclusion. An open reconstructive operation is a safe and effective method of preventing complications of aneurysms of the extracranial portion of the carotid artery.

KEY WORDS: extracranial carotid artery aneurysms, open reconstructive operation.
