Angiotensin-converting enzyme inhibitors and angiotensin receptor antagonists should be held the morning of surgery and restarted after the patient is euvolemic (Grade 1, Level B).

Preoperative hydration is recommended for patients with renal insufficiency prior to aneurysm repair (Grade 1, Level B).

Intraoperative diuresis using fuorosemide or mannitol is probably not beneficial in reducing the risk of postoperative renal insufficiency after aneurysm repair (Grade 1, Level A).

Pre- and post procedure hydration with normal saline or 5% dextrose/sodium bicarbonate is recommended for patients at increased risk of contrast induced nephropathy (Grade 1, Level B).
