Comparison of Hybrid Vascular Grafts and Standard Grafts in Terms of Kidney Injury for the Treatment of Thoraco-Abdominal Aortic Aneurysm

Background We present a comparison of renal function outcomes during HTAR with the use of a new hybrid vascular graft (GHVG) or standard graft. Methods It is a multicenter, retrospective, observational study. Between January 2015 and March 2019, 36 patients were treated with HTAR. We compared HTAR performed with the use of the GHVG and with the use of standard bypass graft. Primary outcome measures were hospital mortality, acute kidney injury (AKI) at 30 days and GHVG patency. Results Mean GHVG ischemia time was significantly lower for both renal arteries (right: GHVG, 4 ± 2 vs. standard graft, 15 ± 7 min; 95% CI 2.23–6.69, P
