颅脑外伤后进展性出血性损伤的研究进展

Progress in Progressive Hemorrhagic Injury after Traumatic Brain Injury

颅脑外伤后进展性出血性损伤(PHI)系指与颅脑损伤后首次CT检查结果相比,经手术或再次CT扫描证实,患者出现新的出血性病灶或原有出血性病灶扩大。这种出血性病灶可分为:脑挫裂伤、多发性血肿、蛛网膜下腔出血(SAH)、硬膜下血肿(SDH)、硬膜外血肿(EDH)等。PHI是颅脑损伤患者主要致死及致残原因。严密监测、早期治疗对促进患者神经功能恢复,提高患者生活质量具有重要意义。现简要分析PHI的发病机制、高危因素、早期诊断及临床治疗原则。

Progress hemorrhagic injury(PHI) means, compared with traumatic brain injury after the first CT findings, the emergence of new patients with hemorrhagic lesions or expand existing hemorrhagic lesions confirmed by surgery or CT scan again. This bleeding lesions can be divided into cerebral contus ion,multiple hematoma,subarachnoid hemorrhage(SAH),subdural hematoma(SDH),epidural hematoma(EDH) and so on. PHI is the main cause of death in patients with traumatic brain injury and disability reasons. Close monitoring and early treatment had an important significance for promoting recovery of neurological function and improving the quality of patients' life. In this paper,we made a brief analysis of the pathogenesis of PHI,the risk factors,early diagnosis and clinical treatment principles.
