Abstract:
The authors describe a rare case of internal carotid artery (ICA) trifurcation aneurysm and its surgical management. Carotid trifurcation is a unique anatomical variant where three arterial branches arise from the carotid termination than the usual two. Aneurysm arising from the trifurcation, due to its rarity, is difficult to treat. The anatomy, embryological basis and significance of such an anomaly during surgical management are discussed.
