[Acute renal failure in a prominent aneurysm of the iliac artery].

This is a report on a patient of 64 years of age who was admitted to hospital as an inpatient thirteen years after obliteration of the iliac artery with an extension plasty. He complained of irregular stools and occasional abdominal pain. Imaging methods were employed on account of a drop in the haemoglobin count, progressive renal insufficiency and a palpable tumor in the lower abdomen. These methods supplied evidence of a false aneurysm originating from the iliac endarterectomy, combined with compression of the ureter and small intestine. Based on the present case report, the general complex of problems in diagnosing aneurysms of the iliac artery is discussed.
