Rupture of an aneurysm into the gastrointestinal tract is not a common occurrence. In 1942 Rottino1 reviewed the literature and collected 32 such cases, and since that time 24 additional ones have been added.* Including this present report, the total number of cases is now 58. Since aneurysms occur principally in the aged, we will see more of this complication as our population continues to grow older. In view of this and since this disease is theoretically curable, it deserves our attention. It should be considered whenever an elderly patient with massive bleeding into the gastrointestinal tract is seen.
Aneurysms of the abdominal aorta are classified according to etiology as arterio-sclerotic, syphilitic, mycotic, or traumatic.9 Arteriosclerosis is by far the commonest cause of these aneurysms. Syphilis is the next commonest cause. Aneurysms due to other pathological processes are extremely rare. Arteriosclerosis was the cause of the abdominal aneurysm
