Ruptured Internal Carotid Artery Pseudoaneurysm 10 Years after Cervical Spine Surgery

摘要

An iatrogenic internal carotid artery (ICA) pseudoaneurysm is an extremely rare complication of cervical spine surgery. Here we report an extraordinary case of massive hematemesis due to a ruptured ICA pseudoaneurysm caused by the laminoplasty plate 10 years after cervical spine surgery. Computed tomography angiography revealed a ruptured 4×10-mm left extracranial ICA pseudoaneurysm probably connected to the pharynx. Emergent surgery was performed because of the uncontrolled massive bleeding. After complete resection of the injured segment, an interposition graft with a 6-mm polytetrafluoroethylene graft was placed and the fistula tract to the pharynx was repaired.
