快速自然消散的颅内血肿

Rapid Spontaneous Resolution of Intracranial Hematoma

目的 为探讨快速自然消散的颅内血肿的消散机理及临床特点。方法 回顾性分析17例快速自然消散的颅内血肿的临床表现及CT特征。结果 72 h内17例颅内血肿8例明显缩小,9例完全消散。结论 快速自然消散的急性硬膜外血肿多发生于青少年,与血肿部位的颅骨骨折有关;而急性硬膜下血肿的快速消散与CSF向硬膜下腔移行、冲洗以及颅内压增高对血肿的挤压或脑萎缩对血肿的再分布提供空间有关。

Objective To investigate the mechanism and clinical characteristics of rapid spontaneous resolution of the intracranial hematoma. Method The clinical and imaging data of 17 patients with intracranial hematomas, which rapid were spontaneously resolved, were analysed retrospectively. Results Of 17 cases with intracranial hematoma, 8 were observed significantly decreasing the hematoma, and 9 dissolving completely within 72 hours. Conclusions The rapid spontaneous resolution of acute epidural hematoma is seen mostly in teenagers and correlates with the cranical fracture which occurred in the hematoma region. The rapid spontaneous resolution of acute subdural hematoma is relative to the transfering of cerebrospinal fluid to subdural space, and the squeeze of the hematoma by the high intracranial pressure or the space supplied by brain atrophy.
