CT Diagnosis of closed hepatic trauma

目的 探讨CT尤其是增强CT在诊断闭合性肝损伤中的价值。方法 收集共32例闭合性肝损伤,其中手术修补者26例,另6例采取保守治疗。27例行肝部CT平扫和增强,5例只行平扫。结果 平扫28例见肝实质内不规则的低密度区,肝周及脾周等部位的液性低密度影是腹腔内积血的重要CT征象。平扫有4例漏诊,增强扫描后损伤部位和程度均清晰显示。结论 肝损伤行平扫加增强CT检查能清晰显示损伤的部位和程度。

Objective To evaluate the value of CT diagnosis, especially contrast- enhancement CT,for closed hepatic trauma. Methods Thirty - two patients with closed hepatic trauma were included this study. 26 cases were perfomanced mended operation, the rest of 6 cases were managed by nonoperative methods,27 cases of all patients were performanced both hepatic CT performancded hepatic CT plain scan only. Results 28 cases heterogeneous hypodense lesions were found in liver by CT plain scan.ligueous hypodense(CT value,45 - 68 HU,approximately)were important CT sign of hemorrhage in peritoneal cavity,4 cases of CT plain scan couldn t be found signs of trauma.However,contrast - enhancement CT scan show the location and degree of trauma clearly.
