Clinical analysis of postoperative complications were made in 1,000 cases of intracranial saccular aneurysm.Psychiatric symptoms, motor disturbances, and aphasia were observed in 107 cases (11.5%),74 cases (7.1%) and 20 cases (2.1%), respectively in 929 discharged cases.Moreover metabolic disturbances of water and electrolytes and gastro-intestinal bleeding were found in 60 cases(6.0%) and 19 cases (1.9%), respectively in 1,000 surgically treated cases including cases of death during hospitalization.Psychiatric symptoms were apt to develop in cases of vertebro-basilar artery aneurysm, multiple aneurysm and anterior communicating aneurysms.There were some tendencies that the poorer the preoperative grade was, the higher the occurrence rate of psychiatric symptoms was.Concerning the timing of surgery, psychiatric symptoms developed most frequently in cases operated at 3-7th day after the subarachnoid hemorrhage. Most of the postoperative psychiatric symptoms consisted of disorientation,character changes, and Korsakoff's syndrome, and they improved in 63% of 107 cases at the time of follow-ups.The occurrence rate of other complications were also investigated in relation to the site of aneurysm, preoperative grading and the timing of surgery in this report.
