title: [A case of giant aneurysm at the anterior communicating artery treated by direct surgery (author's transl)].
abstract: The patient, a 54-year-old male, was suddenly attacked with severe headache and unconsciousness in March 1968. Since then he complained headache and became aware of decreased visual acuity in his right eye. He visited an ophthalmological clinic and was referred to our department of neurosurgery under the suspicion of parasellar tumor. Cerebral angiogram revealed a giant aneurysm of the anterior communicating artery. CT scan revealed a ring shape high density area about 35 mm in diameter and the center of its high density area enhanced by conray infusion. Direct operation was done and succeeded under our prolongation method of the occlusion time of cerebral arteries due to administration of 20% mannitol. Details of our operative method of giant aneurysm at the anterior communicating artery was discussed.
