Explain of Cardiovascular Pathology

48.Aorta, dissection, microscopic

This microscopic cross section of the aorta demonstrates a red blood clot that is compressing the aortic lumen. This occurred as a result of aortic dissection in which there was a tear in the intima followed by dissection of blood at high pressure out through the muscular wall to the adventitia. This blood dissecting out can lead to sudden death from hemothorax.
