摘　　要：本文从 CT 扫描阐明了脑水肿液经脑室内引流而廓清。以略窄于水肿带的长方形测量区,自血肿周围水肿带向脑室方向分4～6区段,测量每一区段的 CT 值,可得出三种曲线,即Ⅰ型递增曲线,本组为70%;Ⅱ型平坦曲线占24%,由于水肿液较长时期经过引流通道致使含水量趋于平衡之故;Ⅲ型不规则曲线占6%,可能是水肿组织中蛋白和(或)脂肪含量变化的关系。This study was trying to determine how the fluid of brain edema cleared into the ventricles as seen on CT scan.Utilizing a long square shape of interest area,which was slightly narrower than edema zone,was used to measure the CT value,starting from the periphery of the hemotoma.The edema zone was divided into four to six areas towards the ventricles.Each zone was measuted and recorded. On the basis of the result of CT Value,it may be chiefly classified into three types of curves.Type I was an increasing gradient curve to be 70% of this group.Type Ⅱ was a horizontal curve,24%;possible the edema fluid went through a drawing pathway as the wa- ter content increased approch to a balance condition for a period of time.Type Ⅲ was an ir- regular curve,6%;it may be related to the change of protein and/or lipiod content in the edematous tissues.
