Answer

The important surgical and endovascular anatomic considerations include associated renal and visceral artery involvement (either occlusive disease or involved in the aneurysm process) and the iliac artery (either occlusive disease or aneurysms). The length of the infrarenal aortic neck is important in helping determine the surgical approach (ie, retroperitoneal or transabdominal) and the location of the aortic cross-clamp.

Consideration of hypogastric artery (internal iliac) outflow is important in planning surgical repair. Loss of blood flow from the hypogastric artery may result in impotence in males and sigmoid colon ischemia with necrosis.
