Aortic pseudoaneurysm is a rare complication after blunt chest trauma or cardiac surgical procedures and can occur at the site of cannulation or root vent insertion on the ascending aorta. These pseudoaneurysms have the potential to expand, erode, and rupture, and detecting this condition before complications occur is the key to successful management. We had replaced the mitral valve with a 31-mm bioprosthesis in an 82-year-old patient and repaired an ascending aorta aneurysm, but a computed tomography scan on postoperative day 18 revealed a pseudoaneurysm at the site of the previous aortic cannulation. Because of the patient’s advanced age and multiple comorbidities, we sealed off the neck of the pseudoaneurysm with a 12-mm Amplatzer Vascular Plug in the interventional cardiology suite instead of subjecting her to a surgical repair involving redo sternotomy and a period of circulatory arrest. Deployment of the Amplatzer plug effectively shut off flow into the pseudoaneurysm, and the patient recovered well. Although the optimal management strategy for aortic pseudoaneurysms is a matter of controversy, endovascular interventions may be a safer alternative to surgery for patients with multiple comorbidities.
