近年来的研究证明,缺血性脑血管病的发病率和病死率远较颅内出血高得多。据统计缺血性脑血管病约占脑血管病发病率的65%。对于缺血性脑血管病的认识较过去也有了进展,缺血性脑血管病的重要性也越来越受到人们的重视。鉴于脑供血不全的血液动力性症状,是因侧支循环不全所致,并非阻塞本身所引起。近年来,在显微外科技术和血管外科技术发展的基础上,开展了颅内外动脉吻合术。借此,能使脑缺血区增加侧支血液供应,以期达到改善局部脑功能的目的,初步证明,这
In recent years, studies have shown that the incidence of ischemic cerebrovascular disease and mortality is much higher than intracranial hemorrhage. According to statistics, ischemic cerebrovascular disease accounts for about 65% of the incidence of cerebrovascular disease. The understanding of ischemic cerebrovascular disease than the past has made progress, the importance of ischemic cerebrovascular disease is also more and more people’s attention. In view of cerebral hemodynamic symptoms of incomplete blood supply, due to collateral circulation caused by incomplete, not caused by obstruction itself. In recent years, based on the development of microsurgery and vascular surgery, intracranial and external arterial anastomosis has been carried out. In this way, it can increase the blood supply of collaterals in the ischemic area in order to achieve the purpose of improving local brain function. It is initially proved that
