[Prospective study of echography versus phlebography in the detection of sural venous thrombosis].
Among all noninvasive techniques, high-resolution ultrasonography used alone has rarely been used for the diagnosis of thrombosis in the calf. Nineteen patients with suspected AVT were examined with ultrasonography and phlebography during 4 months. For each patient, a sonogram and a phlebogram were taken within less than 24 hours and interpreted independently. The sonographic exploration with a high-resolution (5 MHz) transducer covers all deep trunks and muscular veins (soleus or gastrocnemius muscles). The positivity criterion is the persistence of a hypoechogenic endoluminal image under moderate compression. According to the phlebographic data, 65% of the patients present with thrombosis. Ultrasonography has a sensitivity of 95% and a specificity of 99% for the study of the deep trunks. Ultrasonography screens more thromboses than phlebography (23 cases versus 17). On a whole, ultrasonography seems to be more sensitive than phlebography for the diagnosis of recent sural thrombosis.
