Aortic aneurysm in Marfan
WebHistologically, the Marfan aorta is characterised by elastic fibre fragmentation and disarray, paucity of smooth muscle cells, and deposition of collagen and mucopolysaccharide between the cells of the media. These appearances are sometimes described as “cystic medial degeneration” although there are no true cysts present. WebRationale: Cystic medial degeneration Erdheim-Gsell is a vascular pathology mainly of the large vessels, which is mostly associated with Marfan syndrome or Ehlers-Danlos syndrome. The clinical findings of this entity are aneurysms of the aorta or large peripheral arteries which usually present in an acute setting due to rupture of an aneurysm. WebOverexpression and activation of MMP-2protein, accompanying with the down expression of TIMP-2 protein, was associated with myxoid degeneration of elastic and collagen in thoracic aorta caused by Marfan′s syndrome.
