近年来我国一些城市的神经流行病学的抽样调查表明,脑血管病的发病率和死亡率都占首位。致残率高达87％。因而积极开展脑血管病防治的研究,已成为当务之急。在脑血管病中,缺血性与出血性之比约为4.2:1。鉴于脑卒中内科疗法的进展较少,随着显微外科的发展、脑血管吻合术给缺血性脑血管病的治疗开辟了新的途径。我国已成功地完成 In recent years, neuropathological sampling surveys in some cities in China have shown that morbidity and mortality of cerebrovascular diseases both rank first. Disability rate as high as 87%. Therefore, the active prevention and treatment of cerebrovascular disease has become a top priority. In cerebrovascular disease, the ratio of ischemic to hemorrhagic is about 4.2: 1. In view of the progress of medical treatment of stroke is less, with the development of microsurgery, cerebrovascular anastomosis to ischemic cerebrovascular disease opened up a new way of treatment.
