Abstract
A 46-year old man transferred to our hospital with complaints of severe sudden headache and repeated vomiting. CT scan revealed subarachnoid hemorrhage. Subarachnoid hemorrhage thickly covered the left Sylvian fissure and suprasellar cistern. MR angiography demonstrated a cerebral aneurysm, about 5 mm in diameter, at the left middle cerebral artery bifurcation. The patient underwent direct clipping of the aneurysm without conventional cerebral angiography. The postoperative course was uneventful.
We suggest that conventional cerebral angiogram may be omitted with sufficient information from MR angiogram in the aneurysmal surgery.
