Fig. 1 Patient 1. A) Before treatment (images at left): 3D time-of-flight magnetic resonance angiography (MRA) and endovascular exploration of the thoracic aorta show 2 pseudoaneurysms (arrows) at the thoracic abdominal junction, and a small infrarenal fusiform aneurysm (arrowhead). B) After treatment (images at right): MRA image reveals the absence of 1 pseudoaneurysm (arrow), and the endovascular image at the far right also reveals the absence of that pseudoaneurysm.
