[Correlation of surgical timing and prognosis for ruptured intracranial aneurysms]

To explore the correlation between surgical timing and clinical prognosis for ruptured intracranial aneurysms.

A series of 187 patients with intracranial aneurysm treated surgically at our department were analyzed retrospectively. Among them, 101 patients received an average follow-up period of 9 months (range: 6 - 14). Timings of operation that might affect the clinical efficacies of microsurgery were analyzed. The modified Rankin scale (mRS) of discharge and the corresponding follow-up mRS were all analyzed.

Timing of operation was negatively correlated with mRS of hospital discharge (P < 0.05), but it had no correlation with follow-up mRS (P > 0.05); patients whose discharge mRS were 1, 2, 3 or 4 had better long-term efficacies (P < 0.05) while those with a discharge mRS of 5 fare worse (P > 0.05).

The short-term efficacy of early microsurgery for intracranial aneurysms is worse than those of medium and late microsurgery. But no obvious differences exist between the long-term efficacies of early, medium and late microsurgery. The patients whose discharge mRS were 1, 2, 3 or 4 have better long-term efficacies.
