本文从缺血性脑血管病的病理生理改变出发,阐明恢复的关键首在迅速提高缺血区的脑血流。而传统的治疗方法对提高局部脑血流作用小而慢。近年来应用血液稀释治疗,疗效高,安全无创,对后遗症也有效。其机制可能与血液稀释改善血液流变性,提高心输出量,降低周围血管阻力,稀释促凝物质,增加缺血区侧支循环灌注量,快速提高“半暗区”的脑血流,以预防梗死的发生有关。
This article from the pathophysiological changes of ischemic cerebrovascular disease, elucidated the key to recovery in the rapid increase of cerebral blood flow in the ischemic area. The traditional treatment to improve the role of local cerebral blood flow is small and slow. In recent years, the application of hemodilution treatment, high efficacy, safety noninvasive, the sequelae are also effective. The mechanism may be associated with hemodilution to improve blood rheology, improve cardiac output, reduce peripheral vascular resistance, dilute procoagulant substances, increase the amount of collateral circulation in the ischemic area, and rapidly increase the “dark area” of cerebral blood flow to prevent The incidence of infarction related.
