颅脑创伤术后迟发性血肿CT应用价值

目的探讨重症颅脑创伤患者行颅内血肿清除术后CT在及时尽早发现颅内迟发性血肿方面的应用价值。方法收集16例手术后颅内迟发性血肿，分析迟发性血肿的类型、部位、发生时间以及预后。结果颅内迟发性血肿主要可分为硬膜外血肿、硬膜下血肿、脑内血肿三类，发生部位主要为颅骨骨折线区下方，颅骨受力处及其对冲部位，额、颞叶等处为主，发生时间为手术中至手术后72h比较多见。结论CT能够及时准确地判断颅内迟发性血肿的发生，2次及2次以上的CT复查可以提高迟发性血肿的检出率。

CT value of the delayed hematoma after the brain injury operation

Objective To explore value of CT in early detection and timely Delayed intracranial hematoma in patients with severe traumatic brain injury with intracranial hematoma after removal. Methods 16 cases of delayed postoperative intracranial hematoma were collected, delayed hematoma, location, time of occurrence and the corresponding prognosis were analyzed.Results Delayed intracranial hematoma can be classified into epidural hematoma, subdural hematoma, intracerebral hematoma three types, the main positions were below the line of the bottom of the skull fracture, skull by the force and its hedge position, the amount of temporal lobe, et at. Most occurred during surgery or at 72 hours after surgery. Conclusion CT could accurately judge delayed intracranial hematoma, 2 times and more than twice CT would help improve the detection rate of delayed hematoma.
