[Chronic Periaortitis].

Abstract

Chronic Periaortitis Abstract. The term chronic periaortitis encompasses several fibroinflammatory diseases that manifest on or around the abdominal aorta which may be associated with aneurysm formation. Formerly distinct entities are grouped together, such as idiopathic retroperitoneal fibrosis (Ormond's disease), inflammatory aortic aneurysm, and perianeurysmal retroperitoneal fibrosis. They may also occur IgG4-related. The most common complications of these systemic inflammatory diseases are ureteric obstruction and secondary renal failure, but venous compression with congestion and thrombosis may also occur. This review focuses on the diagnosis and treatment of chronic periaortitis. The diagnosis is usually made by cross-sectional imaging, and various therapies, especially immunosuppressive agents, are used therapeutically, although good evidence is largely lacking. For bridging, a ureteric stent is often placed and in individual cases surgical therapy is also necessary. Due to the heterogeneity of the diseases and their rarity, there are hardly any standardized treatment procedures.
