- W2003606871 abstract "Seven hundred and eighty patients with intracranial aneurysm, which were surgically treated by the author since 1976, were analyzed. Strategies important for intracranial aneurysm surgery were the timing of surgery, preoperative preparation and intraoperative management. The best management outcome could be achieved by early operation, removal of subarachnoid blood clot, maintenance of circulating blood volume, administration of nimodipine, and meticulous surgical tactics to avoid pitfalls. Indications for aneurysm surgery in the acute phase were determined by intracerebral hematoma, angiographic findings, clinical grade, general physical status and readiness of the surgical team. Important goals to be considered during the operation were obtaining a slack brain, preparation of proximal control, protection of the brain, awareness of microsurgical anatomy, and complete dissection of the sac. The morbidity and mortality were 2.7% and 4.0%, respectively. The mortality was attributed to intracranial causes in 20 cases (poor grade, delayed ischemic deficits, rebleeding, postoperative infarction, and postoperative epidural hematoma), extracranial causes in 7 cases (pulmonary embolism, heparin induced intracerebral hemorrhage, hepatic failure, myocardial infarction, and gastrointestinal bleeding), and unknown problems in 5 cases. The postoperative intracerebral hemorrhage occurred in 16 cases and seemed to be caused by one or more of the following events: cerebral infarction developed during the preoperative period, occlusion of the cerebral veins during the Sylvian dissection, cerebral retraction and/or sudden change of intracranial hemodynamics. Hydrocephalus, almost always a communicating type as confirmed by isotope cisternography, was managed by lumboperitoneal shunt.(ABSTRACT TRUNCATED AT 250 WORDS)" @default.
