目的 探讨脊髓海绵状血管瘤的诊断和显微外科治疗.方法 系统回顾性分析14例脊髓海绵状血管瘤患者的临床特征、诊断和显微外科治疗方法,评价患者术前术后的脊髓功能. 结果 14例均采用显微外科治疗,术后病理证实为海绵状血管瘤.髓内型11例,髓外硬膜下型2例,硬膜外型1例.血管瘤全切除13例,次全切除1例.术后患者症状好转9例,无变化3例,加重2例.无手术死亡.结论 MRI对脊髓海绵状血管瘤诊断的特异性高,显微手术治疗效果好.

Objective To study the therapeutic effect of superficial temporal artery-middle cerebral artery (STA-MCA)anastomosis combining with original encephaloduromyosynangiosis in adults with moyamoya disease.Methods 23 direct STA-MCA bypasses combining with encephaloduromyosynangiosis were performed on 23 hemispheres in 18 cases of ischemic-type and 5 cases of hemorrlogic-type moyamoya disease.Results The cerebral blood flow increased immediately aher operation.The ischemic symptoms were relieved in all the patients.No rebleeding was found on follow up.There's a complication of operation related sinall infarction.Conclusion Indirect revascularization using temporal muscle(the deep temporal artery)and the dura mater(the middle meningeal artery)is named as"encephaloduromyosynangiosis(EDMS)".The combination of STA-MCA bypass with EDMS is a rational approach in treating of adult moyamoya disease.
