Mediastinal pseudoaneurysm is a rare complication of cardiac and aortic surgery. We report a 55-year-old woman with mediastinal pseudoaneurysm ruptured into the right ventricle outflow tract. The pseudoaneurysm developed after the ascending aort replacement due to suture line dehiscence and it was re-operated successfully with no need to replace the graft. This case illustrates that mediastinal pseudoaneurysm is a potential complication after aortic surgery and it has the ability of rupture into the neighboring structures.
