Long-term Renal Outcomes of Consecutive Patients Undergoing Open Type IV Thoracoabdominal Aneurysm Repair

ObjectiveTo evaluate long-term renal outcomes after open type IV thoracoabdominal aneurysm (TAAA) repair.DesignRetrospective analysis of a prospectively collected database of consecutive operated non-ruptured type IV TAAAs (2007–2011).MethodsRenal function was analysed by serum creatinine concentration, estimated glomerular filtration rate (eGFR) and Kidney Disease Outcomes Quality Initiative (KDOQI) stage. The primary outcome was the change in creatinine concentration from before surgery to defined time points after surgery: peak postoperat
