Hereditary angioedema and aortitis.
A 28-year-old male with hereditary angioedema died of an extensive stroke. Autopsy revealed cicatricial aortitis with narrowing of the coronary ostia, myocardial infarctions, and a left ventricular mural thrombus. There was neither acute inflammation of the aorta nor systemic vasculitis. A possible association of the aortitis with the hereditary angioedema is discussed.
