In a wall of an aorta syphilitic gummas are sometimes found. Tuberculous aortitis develops with a corresponding lesion of the lymph nodes, lungs, mediastinal organs, retroperitoneal space. Specific granulations and foci of prednisone pills necrosis are formed in the vascular wall. Tuberculous aortitis is characterized by the presence of ulceration of the endothelium, aneurysms, calcification of the aortic wall, perforations. Rheumatic damage to the aorta proceeds according to the type of panaortitis.
Purulent aortitis is accompanied by phlegmonous or abscessing inflammation of the aortic wall, its dissection and perforation. Usually, inflammation passes to the aortic wall from neighboring organs, surrounding tissue, or due to septic thrombosis. Ulcerative-necrotic aortitis is usually a consequence of bacterial endocarditis, sepsis, less often - a complication of operations on the aortic valve or patent ductus arteriosus.
