[Inflammatory aortic aneurysm after vascular-prosthetic treatment. Morphological findings after years of incorporation].
Until now the causal and formal pathogenesis of the inflammatory aortic aneurysm is poorly known. This report shows the pathological- anatomical findings of surgical and autoptical preparations, on the one hand 78 months and on the other hand 82 months, after vascular-prosthetical treatment of inflammatory aneurysms in the abdominal and thoracal part of the aorta. By morphological studies it was possible to reveal, the over years existing disease, the typical picture of inflammatory aneurysm, focal destruction of the genuine aortic wall and partial substitution by inflammatory-fibrous, less qualitative granulation tissue. Even 6 1/2 years past the implantation of the Dacron-prosthesis, there is still no complete ingrown. In addition to the known findings of the transprosthetical organization with a variable development of the outer connective-tissued coat and neointima, the incorporated granulation-tissue was overlapped by a strong inflammation according to the basic disease. In several parts of the inflammatory destructed aortic wall, there is still no fixed incorporation of the prosthesis after 7 years, so that "hypermobile-prosthetic-parts" can be found as a result.
