Pulmonary Arteriogram Showing Three Separate AVMs and Respective Supplying Arterial BranchesThe initial arteriogram from the main pulmonary artery demonstrates three separate AVMs in the medial segment of the right middle lobe, a lateral segment of the left lower lobe, and an anteromedial segment of the left lower lobe (red circles). The two larger AVMs correlated with the observed findings on the initial CT of the chest. An occult AVM (red circle, bottom right of image) was only definitively visualized on CT of the chest, after meticulous retrospective analysis. The yellow arrows demonstrate the pulmonary artery branches that supply the identified AVMs. The blue arrows show the sheath accessing the main pulmonary artery, with the tip of the wire displayed by the purple arrow. The trachea can be seen outlined in black for visual reference.
