CTICasesAscending aortic pseudoaneurysm
Imaging findings
Chest CT and angiography demonstrate a giant, pulsatile, contrast-filled pseudoaneurysm arising from the ascending aorta, extending anteriorly into the chest wall through a prior sternectomy site. Coils are deployed within the pseudoaneurysm cavity alongside an ascending aortic stent graft.
Key takeaways
Ascending aortic pseudoaneurysm is a severe, life-threatening complication of prior cardiothoracic surgery. Endovascular management with stent-graft placement and coil embolization represents a viable temporizing or definitive therapeutic option in high-risk surgical candidates.
