Forty-five patients underwent surgery for unruptured cerebral aneurysm.
Postoperative brain damage occurred in 3 cases (6.7%). The possible causes of the damage were venous infarction. One patient died due to pneumonia induced by bilateral recurrent nerve palsy. Two other patients developed transient neurological deficits. One venous infarction was induced by the combination of postoperative meningitis and minor injury of the vein during surgery. This patient recovered by external decompression surgery and barbital coma therapy.
A careful preoperative assessment and intraoperative management of cerebral vein adhesive to cerebral aneurysm is indispensable.
