Abstract

Aortic dissections are life-threatening emergencies characterized by an intimal tear within the aortic wall, resulting in a false lumen. Progressive aortic dilation following repair may predispose patients to aneurysm or pseudoaneurysm formation, increasing the risk of rupture and fatal complications.
A 42-year-old man with prior type A (DeBakey type 1) aortic dissection repair presented with acute chest pain and was found to be in a hypertensive emergency with residual aortic dissection. Despite aggressive blood pressure and heart rate control, imaging demonstrated the development of a 2.5-cm pseudoaneurysm near the right coronary artery origin.
This rare presentation highlights the importance of surveillance and serial imaging in patients with prior aortic dissection, as delayed vascular complications may occur despite management.
Patients with prior aortic dissection repair remain at risk for delayed, life-threatening complications. Individualized management and long-term surveillance are essential for early detection of pseudoaneurysm formation and timely intervention.
