180-degre carotid bifurcation with an internal carotid artery aneurysm

Abstract

Purpose: Internal carotid artery (ICA) aneurysm is a rare pathology. In the clinical case we present, the patient had an ICA aneurysm as well as a rare anatomical variant of the carotid bifurcation.

Methods: We present the case of a 45 year old man, who had two episodes of TIA revealed by loss of mind. Computed tomography revealed the fusiform aneurysm of a left ICA in the first segment with maximal diameter of 16 mm. There were no thrombotic mass in the dilated area. The carotid bifurcation angle was 180 degree. Although the aneurysm did not contain a thrombus mass, it was considered the source of the TIA because of turbulent blood flow.

Results: Distal and proximal ligation was performed. A 5-cm long graft from the great saphenous vein was used for ICA revascularization from common carotid artery.

Conclusion: In our case, geometry of carotid bifurcation may have contributed to the ICA aneurysm, although there is no evidence for this correlation.
