Title: Correlation between pulmonary embolism and ultrasonic imaging in characteristics of distributions of deep venous thrombosis of lower extremities
Abstract: Objective To analyze the characteristics of distributions of deep venous thrombosis(DVT) of low extremity and discuss the diagnostic value by 2D-CDFI on isolated calf vein thrombosis.Methods 121 cases with 132 lower extremities with clinically diagnosing DVT were studied.All patients were scanned by 2D and CDFI,and 18 of them were examined by contrast venography(CV).The relationship between segments,time and ultrasonic characteristics of DVT and PE was discussed and analysed.Results The highest incidental rate of DVT of lower extremities was 42.4% in the segments of the IV class and all of them were detected by ultrasonography.The ratio of left and right calf vein thrombosis was half to half(8∶8),and the incidental of thrombosis in muscular vein(68.8%,11/16) was higher than that in peroneal vein and posterior tibial vein(31.2%,5/16).All thromboses in muscular vein were found by ultrasonography,and in peroneal and posterior tibial veins,2 cases with 3 calf vein thrombosis were not found by ultrasonography and identified by CV.Among 121 cases of lower extremity DVT,30 were caused PE(24.8%).Conclusion 2D-CDFI as a non-invasive examination in calf veins should be examined routinely.It is important to prevent effectively occurance of PE.
