目的　对外伤性脑室内出血的发病机制、治疗原则和预后进行分析评价。方法　总结 40例外伤性脑室内出血的临床特点、治疗方法及两种治疗方法的预后比较 ,找出预后较好的治疗方法。结果　 40例患者入院后急诊行脑室外引流术后 ,格拉斯哥昏迷记分 (GCS)较术前提高 3～ 8分 ,平均提高( 2 .3 3± 1.2 5 )分。应用持续性蛛网膜下腔引流可使脑积水发生率下降 5 0 %。结论　初期脑室外引流和后期持续性蛛网膜下腔引流是有效的治疗手段 ,能够为手术争取宝贵的时间和降低脑积水的发生率 Objective To analyze and evaluate the pathogenesis, treatment principle and prognosis of traumatic intraventricular hemorrhage. Methods To summarize the clinical features and treatment of 40 cases of traumatic intraventricular hemorrhage and compare the prognosis of the two treatment methods to find a better prognosis of the treatment. Results 40 cases of patients admitted to the emergency room after intraventricular drainage, Glasgow coma score (GCS) increased 3 to 8 points compared with preoperative, with an average increase of (2.3.3 ± 1.2 5) points. Continuous subarachnoid drainage can reduce the incidence of hydrocephalus 50%. Conclusions Initial ventricular extracorporeal drainage and subsequent subarachnoid drainage are effective treatments, which can be used for surgery to gain valuable time and reduce the incidence of hydrocephalus
