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.
作者描述了一例罕见的颈内动脉（ICA）三叉分支动脉瘤及其手术治疗情况。颈动脉三叉分支是一种独特的解剖变异，即从颈动脉末端发出的动脉分支为三条而非通常的两条。由于这种三叉分支处动脉瘤十分罕见，治疗起来颇具难度。文中讨论了这种异常情况在手术治疗中的解剖结构、胚胎学基础及意义。
