丘脑出血的临床与CT表现

本文分析82例丘脑出血的CT表现和预后。CT能早期诊断血肿的大小、范围、穿破脑室及出血的演变过程，可以预测丘脑出血的病程和预后。证实丘脑出血临床表现为丘脑综合征，其主要特征为：病灶对侧呈感觉运动障碍而以感觉障碍为主；多出现垂直性注视痹和瞳孔异常；优势半球时可出现语言障碍，非优势半球时可出现结构失用或疾病觉缺失；血肿体积超过3．6cm×1．3cm×3．0cm或出血破入脑室伴明显脑室扩张者病死率显著提高。

THE CLINICAL AND CT MANIFESTATION OF THALAMIC HEMORRHAGE

This paper analysed the clinical and CT manifestation of 82 patients with thalamic hemorrhage. The results showed that CT could determine the range of hemorrhage in early phiastage,involving in ventricle of brain andprogress of hemorrhage. Moreover,CT could confirm the thalamic hemorrhage resulted in thalamic symdrome, whichmanifested as follows:Founctional obstacle of both motor and sensory nerves. ()n the side opposite to hemorrhage focus,the malfunction of sensory was more severe than that of motors. Paralysis of vertical vision and pupil abnormal.Aphasia if the hemorrhage occured in the dominant hemisphere and structural apraxia and lose of sense of illness if itoccured on non-dominant side. The mortality obviously increased when the size of heamatoma was bigger than 14 CBMor blood penetrated into the ventricle of brain.
