Arterial autografts are:

A. Limited by the length of available artery

C. Are the graft of choice for pediatric renal artery grafting.

DISCUSSION: Arterial autografts have limited but well-established clinical uses. They are the graft of choice for pediatric renal artery revascularizations, as they do not appear to be subject to the aneurysmal dilatation that complicates pediatric renal artery vein bypass. The internal mammary artery autograft provides superior patency for coronary artery bypass as compared with the saphenous vein and is thus a very common arterial autograft procedure. Radial artery autografts for coronary bypass are, however, rapidly narrowed by fibrointimal hyperplasia.
