[Duplex ultrasound imaging of vascularization in venous thrombosis].

Vascularization of venous thrombosis. The degree of organisation of an intravenous thrombus is important for therapeutic interventions and the postthrombotic damage. Changes in echogenicity have already been described in B-mode sonography. We investigated 7 thrombosis in the jugular vein looking for intra-thrombotic vessels that occur during the organisation. In 3 thrombosis arterial vessels were found from the 12th to the 17th day. Such arterial vessels appeared only in a short range of time and only in circumscript areas of the thrombus. The intra-vitam documentation of arterial vessels in an organizating intravenous thrombus may give information about the mechanism of thrombogenesis and about the degree of organisation.
