目的:探讨外伤性迟发性颅内血肿的影像学特点及诊断、治疗要点、方法:回顾所遇20例开颅证实为迟发性颅内血肿发生部位,发生时间及其与脑挫裂、颅骨折等原发伤的关系,结果:迟发性颅内血肿的诊断并不困难,在治疗上,积极开颅血肿清除术,必要时去骨瓣减压,术后还应加强综合治疗改善脑缺血、缺氧及微循环。结论:在脑外伤迟发性血肿中,脑挫裂伤,颅骨骨折,硬脑膜或皮层血管、桥静脉断裂可导致不同类型血肿、脑血管麻痹、低氧血症是非手术区迟发性血肿形成病理基础。
Objective: To investigate the imaging characteristics of traumatic delayed intracranial hematoma and the main points of diagnosis and treatment.Methods: The retrospective analysis of 20 craniotomy confirmed the location, time of onset of delayed intracranial hematoma and its relationship with brain contusion, Cranial fracture and other primary injuries, the results: the diagnosis of delayed intracranial hematoma is not difficult, in the treatment of positive craniotomy hematoma removal, if necessary, decompressive craniectomy postoperative should also be strengthened to improve the comprehensive treatment Cerebral ischemia, hypoxia and microcirculation. Conclusion: In the delayed traumatic brain injury, contusion, skull fractures, dural or cortical blood vessels and broken circumflex veins may lead to different types of hematoma, cerebrovascular paralysis, hypoxemia is the formation of delayed hematoma in non-surgical area Pathological basis.
