摘要: 目的

研究加、减速性颅脑损伤的CT影像学特征与损伤程度的关联性。

方法

收集典型加、减速性颅脑损伤案例299例,按致伤方式分为加速性颅脑损伤组与减速性颅脑损伤组,将蛛网膜下腔出血(subarachnoid hemorrhage,SAH)和格拉斯哥昏迷指数(Glasgow coma scale,GCS)与位于受力点同侧以及对侧的颅骨骨折、硬脑膜外血肿(epidural hematoma,EDH)、硬脑膜下血肿(subdural hematoma,SDH)、脑挫伤作为筛选指标,使用χ2检验预筛选和二分类logistic回归分析二次筛选,选出与加、减速性致伤方式关联性最强的指标。

结果

χ2检验,受力点同侧的颅骨骨折、EDH,受力点对侧的EDH、SDH、脑挫伤,SAH,GCS,与加、减速性致伤方式具有关联性(P<0.05)。经二分类logistic回归分析,得出受力点同侧EDH[比值比(odds ratio,OR)为2.697]、受力点对侧脑挫伤(OR为0.043)以及GCS(OR为0.238)有统计学意义(P<0.05)。

结论

受力点同侧EDH、对侧脑挫伤以及GCS可以作为判别加、减速性致伤方式的关键指标,受力点同侧颅骨骨折、对侧SDH、对侧EDH以及SAH判别加、减速性致伤方式的作用相对较弱。

Abstract: Objective

To study the correlation between CT imaging features of acceleration and deceleration brain injury and injury degree.

Methods

A total of 299 cases with acceleration and deceleration brain injury were collected and divided into acceleration brain injury group and deceleration brain injury group according to the injury mechanism. Subarachnoid hemorrhage (SAH) and Glasgow coma scale (GCS), combined with skull fracture, epidural hematoma (EDH), subdural hematoma (SDH) and brain contusion on the same and opposite sides of the stress point were selected as the screening indexes. χ2 test was used for primary screening, and binary logistic regression analysis was used for secondary screening. The indexes with the strongest correlation in acceleration and deceleration injury mechanism were selected.

Results

χ2 test showed that skull fracture and EDH on the same side of the stress point; EDH, SDH and brain contusion on the opposite of the stress point; SAH, GCS were correlated with acceleration and deceleration injury (P<0.05). According to binary logistic regression analysis, the odds ratio (OR) of EDH on the same side of the stress point was 2.697, the OR of brain contusion on the opposite of the stress point was 0.043 and the OR of GCS was 0.238, suggesting there was statistically significant (P<0.05).

Conclusion

EDH on the same side of the stress point, brain contusion on the opposite of the stress point and GCS can be used as key indicators to distinguish acceleration and deceleration injury mechanism. In addition, skull fracture on the same side of the stress point, EDH and SDH on the opposite of the stress point and SAH were relatively weak indicators in distinguishing acceleration and deceleration injury mechanism.
