目的探讨脑弥漫性轴索损伤(DAI)与脑挫裂伤、原发性脑干伤和脑震荡的关系。方法分析56例DAI病人的临床资料和影像学特点,与原发性脑损伤的特征进行比较。结果 56例DAI伤者中66%为交通伤,多次暴力致伤比较常见(61%)。伴脑挫裂伤者40例(71%)。CT/MRI发现出血灶者45例。结论 DAI是常见弥漫性脑损伤,脑震荡和原发脑干伤被包含其中,且常常与脑皮质挫裂伤伴发。将原发性脑损伤分为局限性和弥漫性损伤两大类似乎更为简单实用。
Objective To investigate the relationship between diffuse axonal injury (DAI) and brain contusion and laceration, primary brain stem injury and concussion. Methods The clinical data and imaging features of 56 DAI patients were analyzed and compared with those of primary brain injury. Results 66% of 56 DAI victims were traffic injuries, and multiple injuries were common (61%). Forty cases with brain contusion and laceration (71%). 45 cases of hemorrhage were found by CT / MRI. Conclusion DAI is a common diffuse brain injury, concussion and primary brain stem injury are included, and often associated with cerebral cortex laceration. The primary brain injury is divided into two major categories of limitations and diffuse injury seems more simple and practical.
