Deep Venous Thrombosis with Overlays to Demonstrate Clot and Tram Tracking



The venogram used to be the study of choice to rule out deep venous thrombosis until ultrasound was introduced in the 1990’s. Venography for DVT is rarely used today. However this study shows in a graphic manner, the presence of clots in the deep veins of the calf and shows the tram tracking resulting from the contrast sliding up the sides of the thrombus implying that the clot is not attached to the walls, is loose, and is therefore easily detachable into the circulation with potentially devastating results. The clot is shown overlaid in maroon in b and d. Once the clot is recognized, it is easier to go back to images a and c to identify the white column of contrast alongside the thrombus which gives the appearance of the tram-track.
