Inflammation of the inner lining or interior of the aorta, the largest artery in the body.
From endo- (within) + aortitis (inflammation of the aorta, from Greek aorte + -itis). The term specifically targets inflammation of the aorta's inner surfaces rather than the outer layers.
Endaortitis is extremely dangerous because if the aorta's inner wall becomes inflamed and tears, you can have a life-threatening condition within minutes, which is why doctors carefully distinguish between different layers of inflammation.
