颅内假性动脉瘤的手术治疗

目的探讨颅内假性动脉瘤的诊断和手术方法。方法回顾性分析16例手术治疗的颅内假性动脉瘤病人的临床及影像学特点．其中创伤性9例，感染性7例。结果出院时临床状况优良11例，轻残3例，死亡2例（其中1例为创伤性，术后发生脑梗死）。对12例行3个月。5年门诊随访，均未发生再出血。结论颅内假性动脉瘤是颅内动脉瘤中特殊且较复杂的类型，其诊断和处理策略与一般动脉瘤不同。提高对颅内假性动脉瘤的认识，以及有效应用神经外科技术，可以降低假性动脉瘤的手术风险，改善预后。

Surgery for intracranial pseudoaneurysms

Objective To explore methods for diagnosis and surgical treatment of intracranial pseudoaneurysms. Methods Clinical materials and imaging features of 16 patients with intracranial pseudoaneurysms, including 9 traumatic aneurysms and 7 infectious aneurysms, were analyzed retrospectively. Results Excellent or good therapeutic efficacy was achieved in 11 patients, poor in 3, and dead in 2 at discharging time. One patient with traumatic aneurysm died of postoperative brain infarction, Twelve patients underwent follow-up of 3 months to 5 years without rebleeding. Conclusion Intracranial pseudoaneurysms were special and more complex types of intracranial aneurysms, thereby needing different diagnostic and surgical strategies from general aneurysms. Improving the understanding of intracranial pseudoaneurysms and effectively using neurosurgical techniques during the operation will help reducing the surgical risk and achieve a good surgical outcome.
