There have been no favorable results achieved by the current direct surgical operations for treatment of giant cerebral artery aneurysm even in today's medical society with micro-surgical techniques.
The authors succeeded in the direct operation of the giant anterior communicating artery aneurysm of which extended even to 40×40×35mm in the upper region within the saddle. This patient, a 54-years-old male, was suddenly attacked with severe headache and un-consciousness in March 1968. Since then he complained headache and became aware of decreased visual acuity in his right eye. He visited an eye clinic and was referred to us 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 and its high density area enhanced by conray infusion. Direct operation was done with success under administration of 20% mannitol.
Details of our operative method of giant aneurysm at the anterior communicating artery were discussed.
