Abstract Objective: To investigate the influence of surgical approach and operation timing of microsurgery on the curative effects of posterior circulation aneurysms. Methods: Clinical data of 40 cases of patients with posterior circulation aneurysms admitted into our hospital from May 2011 to November 2017 who received microsurgery were retrospectively analyzed. According to the duration of onset to operation, they were divided into three groups, that is, early stage group (within 3d), middle stage group (4 to 14d), and delayed group (over 14d), 15 cases, 13 cases and 12 cases respectively.In addition, 40 cases of patients with posterior circulation aneurysms treated by microsurgical treatment in our hospital were selected according to surgical approaches. All the patients were divided into extensive pterional approach (11 cases), pterional approach (9 cases), subtemporal approach (13 cases) and retrosigmoid approach (7 cases). And all patients were arranged with 6 months of follow-up. The clinical efficacy and prognosis of different surgical approaches and timing were compared. Results: The clinical efficacy of early stage group was significantly better than middle stage group and delayed group (P<0.05); There was no statistical difference in the rate of good prognosis compared among the three groups (P>0.05); The total effective rate and the rate of good prognosis of pterional approach surgery were significantly lower than extensive pterional approach, subtemporal approach and retrosigmoid approach (P<0.05); There was no statistical difference in the clinical efficacy and prognosis among extensive pterional approach, subtemporal approach and retrosigmoid approach (P>0.05). Conclusion: Different microsurgical approaches and timing will have a certain impact on the curative effect of posterior circulation aneurysms. Choosing appropriate surgical timing and approaches can significantly improve the curative effect, good prognosis and improve the quality of life of patients.
