A rare case of internal carotid artery trifurcation and an aneurysm associated with it

Abstract

Existing literature is devoid of data on true trifurcations of the internal carotid artery (ICA). The authors present a rare case of trifurcation of the ICA, discovered during the evaluation of a patient with subarachnoid haemorrhage, and discuss the surgical implications of the anomaly.
