Vascular Graft Replacement of the Ascending and Descending Aorta: Do Dacron Grafts Grow?

Significant initial expansion and early growth of woven vascular Dacron grafts occurs; it is slightly different in the ascending and descending aorta. Graft expansion should be anticipated when selecting grafts for aortic valve-sparing procedures to prevent development of regurgitation, and, for endoluminal repair of thoracoabdominal aneurysms, to prevent development of type III endoleaks in the projected landing zone.
