老年人上矢状窦旁脑膜瘤术后脑水肿及脑血管痉挛原因分析及治疗体会

目的探讨老年上矢状窦旁脑膜瘤患者术后脑水肿及脑血管痉挛原因及其预防及治疗方案。方法选择本院2003年1月～2006年9月间行经病理证实的老年上矢状窦旁脑膜瘤患者48例,全部经术前CT、MRI检查及手术治疗。术后及时给予抗血管痉挛药物及改善微循环药物,常规腰穿检查颅内压及复查头部CT。结果术后颅内压增高40例(83.3%),术后CT显示脑组织水肿较术前加重32例(66.7%)。术后出现脑水肿及脑血管痉挛致神经功能障碍18例(37.5%),其中经应用抗血管痉挛药物及改善微循环药物的治疗观察1～2w内完全恢复12例(66.7%),4例(22.2%)出院后复查时完全恢复,2例(11.1%)出现脑梗死。无死亡病例。结论老年上矢状窦旁脑膜瘤患者术后脑水肿及脑血管痉挛易造成神经功能缺失,术中皮质引流静脉的保留及保护能有效的减轻术后局部脑水肿的发生;术后早期应用扩容、抗血管痉挛药物及改善微循环药物可有效防治术后脑水肿及血管痉挛的发生及所引起的神经功能缺失。
