Aim. Target of this study was to investigate outcomes after pure surgical treatment of intracranial aneurysms.
Methods. Patients with intracranial supratentorial circle aneurysms were retrospectively reviewed between July 1994 and October 1998. Studied cases were admitted at the Department of Neurosurgery of “ S. Maria - Hospital, Terni, a Government supported General Hospital. One hundred and nine Hunt and Hess Grade 0 to III patients with supratentorial circle aneurysms was studied in order to determine whether advances in the surgical management of intracranial aneurysms have improved surgical outcomes and which factors may predict outcome. All patients were managed only with standard neurosurgical aneurysms clipping procedures. Outcomes evaluation was made at patients’ discharge and classified on the base of the Glasgow Outcome Scale (GOS). Surgical timing, SAH grading, pre and post surgical symptomatic vasospasm, temporary clipping, and intraoperative aneurysm rupture were correlated with outcomes.
Results. Surgical results showed a 75% excellent outcome. Mortality rate was 3%. Hunt and Hess grade 0 highly influenced outcome. Differences in outcomes among grades I to III were not significant. No differences in outcomes related to temporary clipping were noted. A low rate of intraoperative aneurysm rupture is reported: 5 out of 109 cases. In all these cases outcome was good, with neither mortality or morbidity.
Conclusions. Results indicate a progressive improvement in surgical outcomes, suggesting that there still exist margins for improvements in pure surgical management of intracranial aneurysms.
