Detachable balloonを用いてtrappingを行った頭蓋外巨大内頸動脈瘤の1例

抄録

A 61-year-old man was admitted to our hospital, complaining of an enlarging pulsatile hard mass on the left side of the neck. Clinical examination revealed a pulsatile mass in the left laterocervical region and vascular bruit was audible over the mass. Neurological examination was normal apart from bilateral hearing disturbance due to otitis media. CT scan demonstrated a round mass in the left neck, which was homogeneously enhanced by contrast medium. A left carotid angiogram revealed a giant fusiform aneurysm of the extracranial internal carotid artery. Internal trapping of this aneurysm using detachable balloon was performed under EEG monitoring and observation of neurological symptom with successful result. The postoperative course has been uneventful. In this paper, we discuss the advantages of this procedure.
