The retroperitoneal approach for abdominal aortic aneurysm (AAA) has been used to reduce the risk of postoperative ileus and respiratory failure. This technique is usually used in patients with non-ruptured infrarenal AAA because it has been considered to be more time consuming to approach the aorta than the normal transabdominal approach. However, we may not have sufficient information if the aneurysm is confined to the infrarenal abdominal aorta in a ruptured case. In such a situation, the retroperitoneal approach might be better than the transabdominal approach because an aortic clamp can easily be applied to the suprarenal aorta. We report three cases of ruptured AAA treated successfully by the retroperitoneal approach.
