5. Fig 4
Histopathologic cross-section trichrome staining of aorta wrapped with fine Lars Dacron mesh (arrows) in white light and polarized light demonstrates the absence of hematoma formation between the wrap and aortic adventitia and no erosion of mesh through the wall. There is severe fibrosis in the outer half of the aortic wall (A), with diffuse loss of elastic tissue in the media. The medial degenerative changes of the media are associated with adventitial fibrosis with foreign body giant cell reaction associated with the presence of the Dacron wrap. This 33-year-old man with Marfan syndrome underwent aortic valve repair with subcommissural annuloplasties, repair of sinuses with glutaraldehyde-treated pericardial patches, and Dacron mesh wrap of the ascending aorta. Two years later, he required aortic valve repair for severe insufficiency.
