Figure 12 Magnified view from a superior mesenteric artery arteriogram shows an area of abnormal vascularity (white arrowhead) in the cecal area, with an early draining vein (long white arrow) paralleling the arterial inflow (white arrow).
This simultaneous filling of the feeding artery and draining vein is known as the “tram-track” sign and is characteristic of angiodysplasia.
