摘　　要：对９６例自发性脑出血病人ＣＴ扫描３１３次，动态观察不同大小、部位的血肿周围低密度区变化过程，发现其严重程度、分布特点和持续时间与血肿大小、部位密切相关，并将发展过程分为超早期、进展期、高峰期和消退期四期，以指导脱水剂的使用。作者还根据ＣＴ影像变化的特点，结合血肿周围脑组织的病理生理变化，提出血肿周围低密度区既反映脑水肿，又反映周围组织的缺血灶。The clinical series consisted of 96 cases with spontaneous intracerebral hemorrhage. The chronologic changes of the perihematoma hypodensity region in the differant size and site of hematoma were observed by totally 313 serial CT scans . The results suggested that the severity, distribution and lasting time were closely related to the size and site of hematoma. The chronologic change process of the perihematoma hypodensity region were classified as four stages :ultro early, progresive, peak. and resolvent stage, which may be used to guide the clinical application of anhydride drugs. According to the features of CT images, combined with the pathophysiologic changes of the perihematoma brain tissue, we also proposed that the perihematoma hypodensity region reflect the ischemic focus of the perihematoma brain tissue as well as cerebral edema.
