外伤性硬膜下积液占颅脑损伤并发症的3.7%~5.4%~([1]),临床分型为消失型、减少型、稳定型、进展型和演变型,对于前3种类型多采用非手术治疗,演变为慢性硬膜下血肿的演变型多采用血肿外引流术,进展型患者常采用手术治疗,手术方式目前尚无统一标准~([2])。我科自2009年1月至2013年6月应用脑室外引流装置改良钻孔引流治疗进展型外伤性硬膜下积液22例,效果满意,报告如下。对象与方法 Traumatic subdural effusion accounted for 3.7% of traumatic brain injury complications 5.4% ~ ([1]), clinical type disappeared, reduced type, stable type, progressive type and evolution type, the first three types More non-surgical treatment, evolved into the evolution of chronic subdural hematoma more use of hematoma drainage, often in patients with progressive surgical treatment, surgical methods there is no uniform standard ~ ([2]). Our department from January 2009 to June 2013 application of intraventricular drainage device improved drilling drainage treatment of progressive traumatic subdural effusion in 22 cases, the results are satisfactory, the report is as follows.
