Résumé
We experienced 2 cases of cerebral arteriovenous malformation(AVM) with tital extirpation recently. One patient, 23 year old man had chief complaints of sudden headache and loss of consciousness of 3 days duration. On admission, the patient was in a drowsy mental state and had mild papilledema on both sides. Other neurological and physical examinations were normal. Right carotid angiogram revealed AVM which is fed from the right middle cerebral artery and is drained into the right transverse sinus. We found intracerebral hematoma(100 cc) on operative field. The other patient, 30 year old man had chief complaints of Jackson's type seizure several times on the left hand during a five month duration and also had a severe headache intermittently for three months. Left carotid angiogram revealed AVM which is fed from the left anterior cerebral artery and left middle meningeal artery, and is drained into the superior sagittal sinus. We did not find intracerebral hematoma but found an old hemorrhage pouch. The 2 cases of AVM lesions were not found on the postoperative carotid angiogram.
