[Ruptured dissecting aneurysm of the vertebral artery concurrent with contralateral intracerebellar hemorrhage].
A case of a dissecting vertebral aneurysm concurrent with contralateral cerebellar hemorrhage is reported. A 69-year-old man was referred to our hospital for treatment of subarachnoid hemorrhage (SAH). On admission, CT scanning showed SAH and left cerebellar hematoma. Angiography was performed and it revealed a dissecting aneurysm of the right vertebral artery. Proximal clipping of the right vertebral dissecting artery was performed through right suboccipital craniotomy. During the operation, the cerebellar hemisphere gradually became firm, but the operation was finished without any complications. After the operation, the patient's consciousness level decreased from somnolence to semicomatose for a period of 2 hours 30 min. CT scanning showed the left cerebellar hematoma expanding. The cerebellar hematoma was evacuated immediately by midline suboccipital craniectomy, and the patient's consciousness level improved. In such a case, care must be taken to discover the cause of the expansion and to prevent concurrent hematoma during the operation. Through this case, discussion was held concerning the pitfalls of treatment of aneurysmal subarachnoid hemorrhage concurrent with intracerebral hematoma in the remote region.
