急性硬膜外血肿“漩涡征”的影像学意义及其与患者预后相关性分析

目的分析CT平扫判断急性硬膜外血肿"漩涡征"的影像学意义与患者预后。方法选取2013年1月到2014年12月在我院接受治疗的急性硬膜外血肿共42例,根据颅脑CT有无漩涡征分为:涡旋征组22例,非涡旋组20例。及时对患者行手术治疗,观察患者术后恢复情况。结果经过手术治疗后患者的GCS评分均不同程度的提高,差异具有统计学意义(P均0.05),两组术后GCS评分比较,差异具有统计学意义(P=0.037);两组病死率、治愈率比较,差异具有统计学意义(χ2=9.31,8.28,P0.05)。结论 CT平扫对于检查急性硬膜外血肿患者意义重大,若显示"漩涡征"应对患者尽早行急诊手术,提高患者生存率。

The Imaging Significance of "Whirlpool" Sign of Acute Epidural Hematoma and the Correlation Study between "Whirlpool" Sign and the Prognosis

Objective To analysis the imaging significance of "whirlpool" sign of acute epidural hematoma on CT scan and the correlation study between "whirlpool" sign and the prognosis.Methods A total of 42 cases of acute epidural hematoma patients treated in our hospital from January 2013 to December 2014 were includeed in the study, all patients were on CT scan, and received surgical treatment, observed the postoperative recovery. The 42 cases were divided into two group, "whirlpool" group(22 cases) and the "without whirlpool" group(20 cases).Results The GCS score after operation was significantly higher than preoperative, the difference was statistically significant (P<0.05); and there was difference between the "whirlpool" group and the " without whirlpool" group, P<0.05. There was statistically difference of fatality rate and the recovery rate between the two groups (χ2=9.31, 8.28, P<0.05).Conclusions CT scan was significant for the diagnosis of acute epidural hematoma, and it’s better to received surgical treatment if the patients combine with “whirlpool” sign, which would improve the survival rate of patients.
