[Bilateral measurement of peripheral venous pressure: an additional test in the diagnosis of postthrombotic syndrome].

1123 measurements of peripheral venous pressure were performed on 587 patients with a tendency towards swelling in the legs. In 93 the measurements raised suspicion of obstruction to deepvein flow, confirmed by phlebography in 91, i.e. correct positive diagnosis by venous pressure measurements in 97.8%. In 57 patients with normal venous pressure measurements but clinical suspicion of deep-venous thrombosis, phlebography always confirmed the venous-pressure measurements, which are thus superior to routine clinical examinations.
