[Mycotic aneurysm of superior mesenteric artery (author's transl)].

Reference is made to a case of mycotic aneurysm of the superior mesenteric artery caused by bacterial endocarditis with streptococcus feacalis combined with reversible neurologic complications. On account of improvement in the treatment a careful radiological examination is very important with exact account of the size and localisation of the aneurysm. Our patient was successfully treated with aneurysmectomia and reconstruction of the vessel by transplantation of a vein.
