Aortic patch. Definition

Medical Definition: aortic patch

Piece of aorta surrounding the exit of the renal artery and preserved in the removal of kidneys from cadaver donors to facilitate anastomosis with the iliac artery or external, to prevent stenosis at that level. The same process is performed at the level of the renal vein (vena cava patch.) It is not possible in the living donor, it would lead to aortic stenosis. Currently kidney harvesting is done collectively, with a good piece of aorta and cava.
