讨论1.出血部位:本组中3例为基底-被盖型,2例为被益型;4例出血波及中脑,其面积小于桥平面的1/4,出血主要限于一侧。破入第四脑室的2例亦未向其它脑室、脑池进展,出血最大径2.0cm。均<4ml,按10mm为一个CT扫描层未有超过3层者,这与文献报告相符。可以认为只要不是广泛型出血,出血未向丘脑、丘脑下部及四脑室外其它脑室进展, Discussion 1. Bleeding site: In this group, 3 cases were basal-covered, 2 cases were benefit type; 4 cases of bleeding involving the midbrain, the area is less than 1/4 of the bridge plane, bleeding is mainly confined to one side. Break into the fourth ventricle in 2 cases did not progress to other ventricles, cerebral pool, the maximum diameter of 2.0cm. All <4ml, according to a 10mm as a CT scan layer does not exceed 3, which is consistent with the literature. It can be considered that as long as not extensive bleeding, bleeding to the thalamus, hypothalamus and other four ventricle outside the brain progress,
