大脑中动脉瘤的显微外科治疗

目的：报道３４例大脑中动脉瘤显微外科手术的经验。方法：３４中１例有２个动脉瘤，共计３５个动脉瘤，其中大和巨型动脉瘤１４个（４０％），除２个大脑中动脉主干棱形动脉瘤行动脉瘤包裹，２个巨型动脉瘤行Ｍ１阻断伴颅内外动脉吻合外，其余（８８％）均做动脉瘤颈夹闭或动脉瘤切除。结果：无手术死亡，２例术后发生神经缺失。平均随访６年，优良率达９３．８％。结论：显微外科手术治疗大脑中动脉瘤，成功率高，效果好，该项技术值得推广应用。

MICROSURGICAL TREATMENT OF MIDDLE CEREBRAL ARTERY ANEURYSMS

Objective:To report the curative result of middle cerebral artery aneurysms treated by microsurgical technique.Methods:34 patients with 35 middle cerebral artery aneurysms(MCAA),in which 14(40%)were large or giant aneurysms underwent microsurgical operations were reported.Aneurysms clipping or ligation and/or aneurysms resection were performed in 30 cases(88%),wrapping in 2 fusiformed aneurysms at main trunk of middle cerebral artery,M1 occlusion with extra-and intracranial artery bypass in the other 2 giant aneurysms. Results:There was no surgical mortality.Neurological deficite occurred postoperatively in 2 patients.A follow-up of average 6 yeras showed excellent and good rate was in 94%.Conclusion:Microsurgical technique is an ideal and effective method of treatment for middle cerebral artery aneurysms,successe rate is high.
