维生素K缺乏症颅内出血的CT表现

CT manifestation of intracranial hemorrhage due to vitamin K deficiency

目的 探讨维生素K缺乏症颅内出血的CT表现。方法 对 2 0 0 2年 1月至 2 0 0 3年 12月我院经CT确诊的 5 0例患儿进行回顾性总结。结果 CT显示蛛网膜下腔出血最多见占 96% ,其次为硬膜下血肿占 44 % ,脑内出血占 40 % ,单纯脑室出血和出血性脑梗塞较少见 ,有两个部位以上出血的占 14 % ,有脑水肿表现的共 2 1例 (4 2 % ) ,患侧脑室受压变小占68%。结论 CT能明确维生素K缺乏症颅内出血的部位、出血量 ,判断其预后与转归。

Objective To discuss CT findings of intracranial hemorrhage caused by delayed vitamin K deficiency. Methods CT features of 50 patients, who were hospitalized from Jan 2002 to Dec 2003 with intracranial hemorrhage diagnosed by cranial CT, were retrospectively analyzed. Results Subarachnoid hemorrhage (48/50, 96%), subdural hemotoma (22/50, 44%), intracerebral hemorrhage (20/50,40%), and, rarely, intraventricular hemorrhage and hemorrhagic cerebral infarction were found in CT scans. Seven patients (14%) had hemorrhage more than two sites. There were also some attendant features, such as cerebral edema (21/50,42%) and lateral ventricle decrease caused by compression (34/50, 68%). Conclusion CT can accurately locate the hemorrhage, estimate the amount of hemorrhage, so as to assess the prognosis in patients of later vitamin K deficiency.
