Abstract
Aortic pseudoaneurysms, rare but potentially life-threatening complications following coronary artery bypass grafting (CABG), are ideally addressed with re-exploration and open repair. We present a 67-year-old female who had recently undergone a CABG and developed a large mediastinal pseudoaneurysm from the site of the proximal saphenous vein graft anastomosis but was at prohibitive risk for redo open surgery due to significant comorbidities. An application of current endovascular devices was required to treat this post-CABG complication. Thoracic endovascular aortic repair of the ascending aorta was effective in treating the aortic pseudoaneurysm CABG complication in this patient who was at prohibitive risk of redo open surgery.
