Abstract：Objective To investigate the diagnostic value of vascular ultrasound for deep venous thrombosis（DVT）in patients with lower limb fractures. Methods A total of 325 patients with unilateral lower limb fractures who were treated in the hospital were selected as the subjects.All subjects underwent vascular ultrasonography and CT angiography before surgery.The detection of DVT by the two methods was compared. Results A total of 68 patients having 78 veins with thrombosis were detected by ultrasound,and 69 patients having 81 veins with thrombosis were detected by CT venography.A total of 78 blood vessels detected by the two methods were completely consistent.There was 1 iliac vein,1 posterior tibial vein,and 1 anterior tibial vein thrombosis not detected by ultrasound.Taking the results of CT venography as the standard,the sensitivity and misdiagnosis rate of ultrasound for DVT were 96.29% and 3.71%,respectively.There was no statistically significant difference in the detection rate of complete obstruction,incomplete obstruction,recanalization after organization or establishment of collateral circulation between ultrasound and CT venography（P>0.05）. Conclusion The diagnostic efficiency of ultrasound is comparable to that of CT venography in the diagnosis of DVT in patients with lower limb fractures,and it can provide a reference for clinical diagnosis.
