Abstract:
Objective To evaluate the value of two-dimension and color Doppler flow imaging(CDFI) in diagnosis of deep venous thrombosis(DVT) for different segments of lower extremity compared with digital subtract angiography(DSA). Methods Fifty-eight patients suspected of DVT enrolled in the study. Every segment venous of affected extremities was observed by CDFI. All patients underwent DSA examination. CDFI findings were compared with the results of DSA. Statistical analysis was according to quadruple tabular form. The indexes include sensitivity, specificity, accuracy, false positive rate and so on. Every segment of lower extremity deep venous was evaluated and analysis. Results Total of 150 vessels of fifty-eight patients were detected with CDFI and DSA. Evaluation findings of statistical analysis with quadruple tabular form as follows= sensitivity of common lilac vein was 82.6%, specificity was 66.7%; sensitivity of external lilac vein was 83.3%, specificity was 80.0%; sensitivity of hypogastria vein was 80.0 %, specificity was 66.7%;sensitivity of popliteal vein was 92.6 %, specificity was 92.2 % ;sensitivity of femoral vein was 96.2%, specificity was 93.8% ; sensitivity of anterior tibial vein was 71.4%, specificity was 75.0%; sensitivity of posterior tibial veins was 72.7%, specificity was 75.0%. Conclusions As the first-choice examination for DVT, ultrasonography has different diagnostic value for different segment of venous. It is more sensitive and accurate for femoral, popliteal and external iliac veins thrombus, but less sensitive for anterior,posterior tibial veins and bypass circuit vessels.
