外伤性硬膜下积液向慢性硬膜下血肿转化的相关因素探讨

目的:探讨外伤性硬膜下积液向慢性硬膜下血肿转化的相关因素。方法:外伤性硬膜下积液患者186例,其中转化为慢性硬膜下血肿56例(血肿组),未转化130例(无血肿组),对所有患者的临床资料进行统计总结,采用单因素及Logistic多因素分析影响外伤性硬膜下积液向慢性硬膜下血肿转化的相关因素。结果:单因素分析结果显示,血肿组较无血肿组伤后发生硬脑膜下积液时间早、额颞部发生率高、早期手术率低、伤后硬膜下积液厚度厚、积液CT值高,差异均有统计学意义(P0.05);Logistic多因素分析结果显示,额颞部硬膜下积液、伤后硬膜下积液厚、积液CT值高为硬膜下积液向慢性硬膜下血肿转化的危险因素。结论:额颞部积液、积液较厚、积液CT值较高的外伤性硬膜下积液转化为慢性硬膜下血肿的风险较大。

The Factors associated with Transformation From Traumatic Subdural Hydroma to Chronic Subdural Hematoma

Objective:To explore the factors which may be associated with transformation from traumatic subdu-ral hydromato chronic subdural hematoma. Methods: The clinical data of 186 cases with traumatic subdural hy-droma, of which 56 cases transformed into chronic subdural hematoma (hematoma group) and 130 cases without subdural hematoma (non-hematoma group), were analyzed. The factors which may influence the transformation from subdural hydroma to chronic subdural hematoma were analyzed by single factor analysis and Logistic mul-ti-factor analysis. Results: Single factor analysis showed that in the hematoma group early occurrence of traumatic subdural hydroma, higher percentage of frontotemporal subdural hydroma, early operation, larger traumatic subdu-ral hydroma on CT were evident when compared to those in the non-hematoma group (P<0.05). Logistic mul-ti-factors analysis confirmed the observation. Conclusion: Frontal temporal traumatic subdural hydroma, thicker-hydroma and higher CT value of hydroma, are the factors associated with the transformation from subdural hydro-ma to hematoma.
