[Aneurysm of the gluteal artery].

A 90 year old man developed the rare lesion of an aneurysm of the gluteal artery, provoked by an injury in a patient with atheromatous multiple aneurysm disease. The inflammatory and permanent nature of the sciatic pain, the history of a recent increase in size of the buttocks, as well as signs of a deglobulization suggest the need for urgent arteriographic exploration for precise definition of the arteries supplying the aneurysm. Surgical treatment is by primary ligature of the hypogastric artery associated with a direct approach in order to perform endoaneurysmorhaphy.
