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

Unlabelled: 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.
