  • Abstract
  • Look Inside

A 47-year-old man presented with the sudden onset of severe headache and left hemiplegia. CT showeda large hematoma in the right thalamus and internal capsule with intraventricular hemorrhage. Right caro-tid angiography disclosed occlusion of the terminal portion of the right internal carotid artery withmoyamoya vessels and a small aneurysm at the perforator of the right anterior choroidal artery. Thefollow-up angiography 17 days later disclosed definite enlargement of the aneurysm. The aneurysm corre-sponded to the lateral portion of the hematoma on CT and was considered to be the source of bleeding. Endovascular embolization was performed using a platinum coil, and the aneurysm was completelyoccluded with preservation of the parent artery. No change in the patient's neurological status was seenduring and after the procedure.

The management of peripheral artery aneurysms associated with moyamoya disease is controversial. Wesuggest that surgical intervention should be considered if the aneurysm is thought to he the source ofbleeding, and that endovascular embolization using platinum coils may be a useful therapeutic alternativefor these aneurysms.
