Indications : Size
 
While there is no absolute size cutoff, most surgeons will begin to recommend repair of ascending aortic aneurysms when they reach approximately 5cm in size. For patients with Marfan’s Disease, surgery may be recommended for smaller sizes. Patients undergoing cardiac surgery for other reasons, primarily those with bicuspid aortic valves, may require concomitant aortic replacement at smaller sizes. Patients with ascending aortic aneurysms greater than 4cm should be followed with CT scans at regular intervals to evaluate growth of the aneurysm, as directed by their physician.
