소뇌 동정맥 기형을 동반한 후하 소뇌 동맥류의 수술적 치험 : 증례보고 Case Report = Aneurysm of the Posterior Inferior Cerebellar Artery Associated with Arteriovenous Malformation

다국어 초록 (Multilingual Abstract)

A case of a ruptured aneurysm originating at the proximal portion of the left posterior inferior cerebellar artery and an arteriovenous malformation in the left cerebellar hemisphere fed by the same artery is reported. The coincidental occurrence of these two vascular anomalies within the posterior fossa is uncommon. Aneurysms of the posterior inferior cerebellar artery require special consideration during surgical planning and operation because of the proximity of the posterior inferior cerebellar artery to the brain stem and to the origin of the lower cranial nerves .
In our reported case, the aneurysm was located 2.7mm from the midline and 4.7mm from the clivus when measured radiometrically. The operation was carried out with the patient in a three quarter prone position through a left lateral suboccipital approach. Clipping of the neck of the aneurysm and total removal of the arteriovenous malformation were performed successfully in a one-stage operation.
