The aortic lumen in healthy animals is characterized by a smooth, whitish surface, but sheep have macroscopic corrugation of the intimal surface thoracic aorta (TA). Our aim was to determine if this finding pathological or physiological. Thirteen aortas were included work together with from cattle (n = 3), goat 1), horses 4), dogs 2), rabbits 2) and pig 1). A corrugated TA seen all less evident cattle. Histologically, multifocal bulging areas that protruded into lumen. outer half tunica media had numerous, randomly distributed muscle islands disrupted arrangement elastic lamella, displacing them towards We conclude physiological must not be misinterpreted as pathological.
