Synonyms and keywords: cystic medial degeneration; Familial thoracic aortic aneurysm (also referred to as familial aortic dissection or cystic medial necrosis of aorta)[1]; it is sometimes called "Erdheim's cystic medial necrosis", after Jakob Erdheim.[2][3]; the term cystic medial degeneration is sometimes used instead of cystic medial necrosis, because necrosis is not always found
Overview
Cystic medial necrosis is a disorder of large arteries. A degenerative breakdown of collagen, elastin, and smooth muscle caused by aging contribute to weakening of the wall of the artery.[4]
In the aorta,this can result in the formation of a fusiform aneurysm. There is also increased risk of aortic dissection.
There is an association between cystic medial necrosis and Marfan syndrome.
