Ischaemic colitis and abdominal aortic aneurysm repair

In this unit, infrarenal AAA repair has a 2.25% rate of IC following repair. The main risk factors for this include emergency repair and preoperative hypotension. An unexplained neutrophilia and progressive renal failure should also heighten clinical suspicions; however, a definitive diagnosis is best made by colonoscopy. Despite emergency colonic resection, the prognosis remains extremely poor with a mortality approaching 90%.
