Abstract:
Objective:To compare the effect of hybrid open-endovascular repair (HOER) and Viabahn open revascularization technique (VORTEC)+HOER in the treatment of thoracoabdominal aortic aneurysms (TAAA).Methods:From Apr 2005 to Jul 2019, 33 TAAA patients underwent HOER including 21 cases of standard HOER, and 12 of VORTEC+HOER. The intraoperative renal ischemia time (RIT), incidence of postoperative acute kidney injury (AKI), rate of renal artery patency (RAP) and another short-term outcome were observed.Results:RIT was significantly shorter in the VORTEC+HOER group than in the standard treatment group [(9±3) minutes vs. (15±6) minutes, P<0.05]. The increase in serum creatinine (SCr) levels on the 1st postoperative day in the standard treatment group was significantly higher than that in the VORTEC+HOER group [(1.68±0.79) μmol/L vs. (1.05±0.06) μmol/L, P<0.05]. AKI occurred in 5 patients in the standard HOER treatment group (5/21, 24%), while no patient experienced AKI in the VORTEC+HOER group (0/12, 0). Conclusion:VORTEC significantly reduces RIT and postoperative SCr increasing, thereby potentially decreasing the incidence of postoperative AKI.
