MSCT在对比剂外渗的急性腹部创伤性动脉损伤诊断中的应用价值

Application value of MSCT in the diagnosis of acute abdominal traumatic arterial injury with contrast medium extravasation

目的探讨MSCT在对比剂外渗的急性腹部创伤性动脉损伤诊断中的应用价值。方法回顾性分析本院2016年1月~2018年12月收治的44例急性创伤性腹部动脉损伤患者及58例腹部非创伤性动脉病变患者影像资料,分析急性腹部创伤性和非创伤性动脉病变所致对比剂外渗的相关性。结果 44例创伤性腹部损伤患者通过MSCT及图像后处理技术共检出59支动脉损伤,其中对比剂外渗34支、非对比剂外渗共25支;58例急性腹部非创伤组共检出58支动脉病变,其中8支存在对比剂外渗。对比剂外渗征象创伤组出现率明显高于非创伤性组(χ^2=24.42,P<0.05)。结论与非创伤组相比,急性腹部创伤性动脉损伤对比剂外渗征象较为常见,MSCT可以较好地显示创伤性对比剂外渗的直接及间接征象。

Objective To investigate the application value of MSCT in the diagnosis of acute abdominal traumatic arterial injury with contrast medium extravasation. Methods The image data of 44 patients with acute traumatic abdominal arterial injury and 58 patients with abdominal non-traumatic arterial disease treated in our hospital from January 2016 to December 2018 were retrospectively analyzed, and the correlation between contrast medium extravasation and acute abdominal traumatic, non-traumatic arterial disease was analyzed. Results A total of 59 arterial injuries were detected in 44 patients with traumatic abdominal injury by MSCT and image post-processing techniques, of which 34 were extravasation of contrast medium and 25 were non-contrast medium extravasation. 58 cases of arterial disease were detected in the acute abdominal traumatic group, 8 of which had contrast medium extravasation. The incidence of contrast medi um extravasation in the traumatic group was significantly higher than that in the non-traumatic group(χ^2=24.42, P<0.05).Conclusion Compared with those of the non-trauma group, the signs of contrast medium extravasation in acute abdominal traumatic arterial injury are more common. MSCT can better show the direct and indirect signs of traumatic contrast medium extravasation.
