Correlations between clinical probability and Doppler ultrasound results in the assessment of deep venous thrombosis

Although the assessment of deep venous thrombosis (DVT) is based on clinical examination, the complementary tests and especially Doppler ultrasound plays the most important role in DVT diagnosis. Objectives: We aimed to establish the correlations between the clinical probability of DVT based on Wells score and the results of Doppler ultrasound exam. Method: We included 382 patients with clinical supposition of DVT divided into 3 groups based upon the probability of DVT (Wells score): low, moderate and high, respectively. All the patients were examined by Doppler ultrasonography. Results: We noticed that DVT was confirmed by Doppler ultrasonography in more than half of the cases; the highest percent of confirmed cases were in the patients with a high probability of DVT (70.58%) whereas the lowest percent was associated with the low clinical probability (14.63%). Discussions: These findings show the importance of the correct management of cases, starting with clinical data and including a complete anamnesis to identify the risk factors for DVT. Conclusions: There is a significant correlation between the Wells score reflected in the probability of DVT and the Doppler ultrasonography findings.
