[Inflammatory aneurysms].

Inflammatory aneurysms are not so frequent, etiology and pathogenesis are uncertain. Resection can be a problem because of the dense inflammatory fibrous reaction. Preoperative diagnosis may be possible with the aid of intravenous urography and CAT-scan. The treatment of choice is an aortic replacement followed by uni- or bilateral ureterolysis and omentoplasty to cover the entire vascular reconstruction and protect the ureters.
