摘要
本文报告了经 CT 证实的9例11处颅脑损伤开颅术后发生在非手术区的颅内血肿。其中邻近型3个,远隔型5个,对侧型3个。发生在脑内5个,脑室内2个,硬脑膜下2个,硬脑膜外2个。死亡5例。用22只猫建立了急性颅高压的动物模型,减压后有18只动物发生了脑内出血。本文对外伤性术后颅内出血的发生机理进行了探讨。认为脑血管自主调节功能丧失,血管床扩张瘀血是术后脑内出血的病理基础。脑血管内外压力差突然增大可能是术后脑内出血的重要因素。
This paper reports 11 postoperative intracranialhematomas in 9 cases of acut head injury,All ofthe hematomas occurred beyond the scope of previousoperation,3 out of the hematomas near the operativearea,5 far from the operative field and 3 on thecontralateral hemisphere.According to the frequenceof the hematomas,there were intracerebralintraventricular,subdural and extradural hematomasrespectively.After operation five out of the ninepatients died.On another hand the animal modelsof acute intracranial hypertension were set up in 22cats,and intracerebral hematomas occurred in 18cats after cranial decompression.Analyzing thecause of postoperative intracranial hematomas.combining with the results of the animal exerimentwe considered that the cause of the hematomasmight be due to cerebral vasomotor disturbrancesresulting in sudden dilatation of cerebral vessel-bedand marked pressure difference between intra-andextra-cranial vessels.
