Aortogram, after coil embolization of the T8 intercostal artery. Note that the postcoil embolization aortoagram demonstrates no contrast opacification of the pseudoaneurysm lumen, a coil mass measuring approximately 1.5 × 3.5 cm, and a gentle regional concave deformity of the aorta, implying that the true lumen of the pseudoaneurysm was larger than what opacified originally.
