[The collateral circulation for occlusion of the three unpaired abdominal arteries (author's transl)].
A fifty-two year old patient had only a short period of abdominal angina, despite occlusion of all three unpaired abdominal aortic branches. An extensive collateral system provided the circulation to the abdominal organs: intercostal arteries and adrenal vessels through the inferior phrenic artery for the coeliac trunk; arteries from the left iliac for the inferior mesenteric artery and through Riolan's arc (type II) for the superior mesenteric artery. Lumbar vessels provided a supply to the proximal territory of the superior mesenteric artery. In addition, it was possible to demonstrate connections between several lumbar arteries; several of these were also occluded proximally.
