探索四叠体池改变对自发性小脑血肿的预后估计。方法观察和治疗７５例经ＣＴ确诊的自发性小脑血肿病人。血肿最大经＜２ｃｍ１６例，２ｃｍ～４ｃｍ３５例，＞４ｃｍ２４例；四叠体池形态改变分为闭塞１５例、受压３１例和正常２９例。枕下开颅血肿清除３２例，立体定向血肿抽吸术３例，单纯脑室外引流术５例，枕下开颅血肿清除加脑室外引流术３例；保守治疗３２例。结果存活５６例，死亡１９例。四叠体池闭塞者１５例，死亡１４例，植物生存１例；四叠体池受压者３１例，死亡４例，存活２７例；四叠体池正常者２８例，存活２７例，死亡１例。结论ＣＴ扫描四叠体池改变能准确估计小脑血肿的预后并对选择治疗方式有重要意义
To explore the prognosis of quadrigeminal pool changes on spontaneous cerebellar hematoma. Methods 75 cases of CT scan of patients with spontaneous cerebellar hematoma were observed and treated. The maximal size of hematoma was <2cm in 16 cases, 2cm ~ 4cm in 35 cases,> 4cm in 24 cases. The morphological changes of quadruplex pool were divided into occlusion in 15 cases, compression in 31 cases and normal in 29 cases. Suboccipital hematoma removal in 32 cases, stereotactic hematoma aspiration in 3 cases, simple cerebral venous drainage in 5 cases, suboccipitating hematoma removal plus ventricular drainage in 3 cases; Conservative treatment in 32 cases. Results of survival in 56 cases, 19 cases of death. There were 15 cases of quadruple pool occlusion, 14 cases of death and 1 case of plant survival. There were 31 cases of quadruple pool compression, 4 cases died, 27 cases survived, 28 cases of quadruple pool normal, 27 cases survived 1 case. Conclusion CT scanning quadruple pool changes can accurately estimate the prognosis of cerebellar hematoma and the choice of treatment is of great significance
