For the treatment of the moyamoya disease, we developed a surgical procedure of Encephalo-duro-aterio-synangiosis (EDAS), which was conducted in 15 cases on 23 sides. As a result we obtained improvement in cerebral vascularization as well as in neurological and electroencephalographic findings in all cases. This report describes an introduction of the procedure and a review of the postoperative cerebral angiograms. Cerebral revascularization by EDAS proceeded on the following steps, and it was confirmed that efficient cerebral revascularization could be obtained 6 months after the operation in almost all cases following the steps: 1) dilatation and increase of dural artery, 2) dilatation of donor scalp artery, 3) cerebral revascularization with the development of visible fine spontaneous anastomoses between the donor scalp artery and the cerebral arteries and 4) further dilatation of the donor scalp artery and retraction of the abnormal rete vasculosum at the base of the brain.
为治疗烟雾病，我们研发了一种脑-硬膜-动脉-血管吻合术（EDAS），该手术共对15例患者的23侧脑部进行了操作。结果显示，所有病例的脑血管形成、神经功能及脑电图检查结果均得到改善。本报告介绍了该手术方法，并对术后脑血管造影进行了回顾。EDAS脑血运重建按以下步骤进行，且证实几乎所有病例按照这些步骤在术后6个月均可实现有效的脑血运重建：1）硬脑膜动脉扩张及增多；2）供体头皮动脉扩张；3）随着供体头皮动脉与脑动脉之间可见的细小自发吻合支的形成实现脑血运重建；4）供体头皮动脉进一步扩张及脑底部异常血管网退缩。
