摘　　要：目的 探讨超声造影(CEUS)在血流动力学稳定的钝性腹部实质脏器创伤诊断中的临床价值。方法 选取我院急救部收治的血流动力学稳定的疑似钝性腹部实质创伤患者42例,均行对比增强计算机断层扫描(CECT)、常规超声及CEUS检查,并评估脏器损伤分级。以CECT诊断结果为标准,计算常规超声及CEUS诊断钝性腹部实质脏器创伤的灵敏度、特异度、阳性预测值、阴性预测值和准确率;比较CEUS与CECT评估各脏器损伤分级的差异。结果 42例疑似钝性腹部实质脏器创伤患者中,CECT诊断阳性患者30例,CEUS诊断阳性患者29例;CEUS诊断灵敏度为93.33%,特异度为91.67%,阳性预测值96.55%,阴性预测值为84.62%,准确率为92.86%。CEUS与CECT在评估各脏器损伤分级方面比较差异无统计学意义。结论 CEUS在血流动力学稳定的钝性腹部实质脏器创伤患者诊断中有一定的临床价值。Objective To explore the clinical value of contrast-enhanced ultrasound(CEUS)in the diagnosis of hemodynamic stable patients with blunt abdominal solid organs trauma.Methods Forty-two patients with suspected blunt abdominal solid organs trauma admitted to the department of emergency in our hospital were selected,enhanced computed tomography(CECT),ultrasound(US)and CEUS were performed,the organ injury was classfied.Taking CECT results as the gold standard,the specificity,positive predictive value,negative predictive value and accuracy of US and CEUS in diagnosing blunt abdominal solid organ trauma were calculated.The difference in organ injury grading between CEUS and CECT was compared.Results In 42 patients with suspected blunt abdominal solid organs trauma,there were 30 injury patients were diagnosed by CECT and 29 injury patients were diagnosed by CEUS,the sensitivity of CEUS was 93.33%,the specificity was 91.67%,the positive predictive value was 96.55%,the negative predictive value was 84.62%,and the accuracy was 92.86%.There was no significant difference in organ injury grading between CEUS and CECT.Conclusion CEUS has certain clinical value in the diagnosis of hemodynamic stable patients with blunt abdominal solid organ trauma.
