目的结合文献探讨外伤性脑积水的发病机理和治疗结果。方法总结34例经CT和MRI证实的外伤性脑积水的临床、影像学表现、治疗结果和愈合。结果34例外伤性脑积水患者除6例因原发性脑损伤及其并发症而死亡外,余均生存。结论外伤性脑积水发病机理是由于外伤血凝块堵塞中脑导水管,红细胞或纤维蛋白阻塞蛛网膜下腔,使脑脊液吸收障碍,后期蛛网膜纤维化,使蛛网膜颗粒吸收脑脊液障碍。
Objective To investigate the pathogenesis and treatment of traumatic hydrocephalus with literature. Methods The clinical, radiographic findings, treatment outcome and healing of 34 traumatic hydrocephalus confirmed by CT and MRI were summarized. Results 34 patients with traumatic hydrocephalus in addition to 6 patients died of primary brain injury and its complications, the remaining survival. Conclusion The pathogenesis of traumatic hydrocephalus is that traumatic blood clots block the midbrain aqueduct, red blood cells or fibrin clog the subarachnoid space, so that cerebrospinal fluid can be absorbed, and the latter arachnoid fibrosis, so that arachnoid granules can absorb cerebrospinal fluid disorders.
