迟发性外伤性颅内血肿研究

目的 探讨迟发性外伤性颅内血肿（DTICH）的临床特点、形成机制、诊断和治疗。方法 对经复查CT或手术探查证实的35例DTICH进行回顾性分析。结果 手术治疗29例，非手术治疗6例，总良好率71．4％，总死亡率11．4％。DTICH多发生于伤后24h内（77．1％），多见于额颞部和颞顶部（82．9％），脑挫裂伤和外伤性蛛网膜下腔出血是其发生的基础。结论 正确认识DTICH早期临床特征及动态CT扫描有助于及时发现DTICH和确定正确治疗方案，是提高DTICH治愈率的关键。

Delayed Traumatic Intracranial Hematoma Research

Objective To investigate the clinical characteristics,pathogenesis,therapy and diagnosis of delayed traumatic intracranial hematoma (DTICH).Methods 35 patients with DTICH were analysed restrospectively,all cases were verified through repeated CT or operation explore.Results 29 cases were treated with operation.6 cases were managed by conservative treatment.The rate of cure and mortality was 71.4% and 11.4% respectively.Most DTICH occured within 24 hours after injury (77.1%).Most of them the lesion were located in frontal temporal and temporal parietal lobe(82.9%).The main reasons of DTICH were contusion of brain and traumatic subarachoid hemorrhage.Conclusions Correctly realised the early clinical characteristics of DTICH and CT monitoring may help to diagnose and treat DTICH immediately.and may help to improve cure rate of DTICH,also.
