【摘要】：目的:以手术发现和病理结果为诊断金标准,探讨高频彩色多普勒超声(CDFI)在急性足踝部外伤性病变的应用。方法:对2013年1月~2015年9月期间,在新疆医科大学第二附属医院经住院及门诊就诊的56位77例临床疑诊为足及踝部急性外伤性病变患者行高频彩超检查,观察其声像图改变及特征,并以手术及病理结果为金标准,评价高频彩超对足及踝部软组织外伤性病变的诊断能力,其中50例疑似为韧带、肌腱、神经、关节等软组织损伤病例同时行MRI检查,比较高频彩超与MRI对足踝部软组织外伤性病变的检查结果;另外21例疑诊合并有足踝部骨折病例同时行X-Ray检查,对高频彩超与X-Ray对足踝部骨折诊断一致性进行评价。结果:高频彩超对50例足及踝部软组织外伤性病变诊断的灵敏度、特异度、阳性似然比、阴性似然比、阳性预测值、阴性预测值分别为70.7%、77.8%、3.18、0.38、93.5%、36.8%;高频彩超与MRI对足及踝部软组织损伤的检查结果及分别对韧带、肌腱、神经及关节损伤的检查结果比较,无明显统计学差异(P0.05)。高频彩超与X-Ray对21例足踝部骨折诊断一致性评价比较,Kappa值=0.871(一致性极佳)。结论:高频彩色多普勒超声对足及踝部急性外伤性病变具有较高的诊断价值,可为临床医师诊治足踝部急性外伤提供客观的影像学诊断依据,并作为足及踝部外伤后常规的影像学检查方法。
[Abstract]:Objective: to investigate the application of high frequency color Doppler ultrasound (CDFI) in the diagnosis of acute traumatic foot and ankle lesions. Methods: from January 2013 to September 2015, a total of 56 patients with suspected acute traumatic foot and ankle lesions in the second affiliated Hospital of Xinjiang Medical University were examined by high frequency color Doppler ultrasonography. To evaluate the diagnostic ability of high frequency color ultrasound for traumatic lesions of soft tissue of foot and ankle, 50 cases were suspected to be ligaments, tendons and nerves. MRI examination was performed in all cases of soft tissue injury such as joint, and the results of high-frequency color Doppler ultrasonography and MRI in detecting traumatic lesions of soft tissue of ankle were compared, and X-Ray examination was performed in 21 cases with suspected fracture of ankle and foot at the same time. To evaluate the consistency of high frequency color Doppler ultrasound and X-ray in diagnosis of ankle fracture. Results: the sensitivity, specificity, positive likelihood ratio, negative likelihood ratio, positive predictive value of high frequency color Doppler ultrasound in the diagnosis of 50 cases of traumatic lesions of soft tissue of foot and ankle were analyzed. The negative predictive values were 70.7 / 77.8 and 3.18 / 0.38 / 93.5 respectively. There was no significant difference between high frequency color Doppler ultrasonography and MRI in detecting soft tissue injury of foot and ankle, and in ligament, tendon, nerve and joint injury. Evaluation of diagnostic consistency of 21 cases of foot and ankle fractures with high frequency color Doppler ultrasound and X-Ray the Kappa value was 0.871 (excellent consistency). Conclusion: high frequency color Doppler ultrasound has high diagnostic value for acute traumatic lesions of foot and ankle, and can provide objective imaging diagnostic basis for clinicians in the diagnosis and treatment of acute trauma of foot and ankle. And as a routine imaging examination method after foot and ankle trauma.
