摘要
目的：为进一步提高对婴儿期维生素Ｋ缺乏症所致颅内出血ＣＴ征像的认识。方法：回顾性分析经临床证实有各种颅内出血的ＣＴ改变共９７例。结果：按颅内出血的部位及并发症分为单纯性、混合性，其ＣＴ改变主要以急性和亚急性出血为主，以蛛网膜下腔出血、硬膜下出血、混合性脑出血多见，常合并有大面积脑水肿。结论：我们认为婴儿期维生素Ｋ缺乏症颅内出血由于静脉广泛渗血所致。大面积脑水肿产生的原因有两个：其一蛛网膜下腔出血导致动脉痉挛，脑组织广泛缺血、缺氧造成对称大面积水肿；其二出血压迫静脉窦造成回流障碍形成静脉性脑水肿。
Objective :In order to increase recognition CT sign of
intracranial hemorrhage caused by deficiency of vitamin K in infant. Methods :97 cases
clinically confirmed were reviewed. Results :The results showed that intracranial hemorrhage
was sorted two types (simplicity and mixed) according to hemorrhage location and
complication.CT images were mostly performed demorstrated hemorrhage,and subarachnoid
hemorrhage,subdural hemorrhage,mixed hemorrhage usually with huge area of cerebral
edema. Conclusion: We considered that main reason of intracranial hemorrhage was venous
bleeding,reason for cerebral edmea being due to artery vasosopasm from subarachnoid
hemorrhage resulting in cerebral ischemia and symmetrical edmea,and sinuses of dura mater
pressed by hematoma,causing circumfluence obstrution and venous edema.
