Adult: Aorta: Clinical TrialRenal perfusion with histidine-tryptophan-ketoglutarate compared with Ringer's solution in patients undergoing thoracoabdominal aortic open repair
Graphical abstract
Results of a single-center, prospective, randomized study comparing the efficacy of Custodiol (Dr Franz-Kohler Chemie GmbH, Bensheim, Germany) renal perfusion on perioperative acute kidney injury (AKI) in patients undergoing thoracoabdominal aortic open repair. This image summarizes outcomes of renal perfusion with Custodiol compared with lactated Ringer's solution for renal protection in patients undergoing open thoracoabdominal aortic aneurysm repair. What emerged from this trial was that patients in the Custodiol group showed significantly less AKI than those in the Ringer's group (49% vs 76%; P = .02) and that the use of Custodiol resulted as protective from the occurrence of any AKI in multivariable analysis (P = .003).

Trial Design and Eligibility Criteria
“CUstodiol Versus RInger: whaT Is the Best Agent? A Randomized Double Blind Trial” (CURITIBA) study is a prospective, single-center, randomized, double-blind, controlled, parallel trial on AKI in patients undergoing TAAA open repair using Custodiol renal perfusion versus an enriched Ringer's solution. The trial protocol (version 4.0, dated March 4, 2015) follows the Standard Protocol Items: Recommendations for Interventional Trials (SPIRIT) 2013 Statement for protocols of clinical trials.
The
Results
In the study period, 113 patients were admitted at the Department of Vascular Surgery of San Raffaele Scientific Institute with a diagnosis of thoraco-abdominal aortic aneurysm, with indication to open surgical repair; 96 patients were considered eligible for enrollment in the CURITIBA trial after review of inclusion/exclusion criteria. Among these, 6 refused to sign or withdrew informed consent from the trial. Finally, 90 patients underwent randomization for intention-to-treat analysis (45
Discussion
Renal injury is a well known serious complication of TAAA surgical repair. Patients who present with renal dysfunction, especially when hemodialysis or hemofiltration is required, are at high risk for the development of additional perioperative complications, including respiratory failure, cardiac events, hemodynamic instability, and spinal cord ischemia.21
Many techniques have been proposed with the aim to improve intraoperative organ protection, including different methods of renal perfusion.
Conclusions
The results of this trial support the use of cold Custodiol solution for perfusion of the renal arteries during open TAAA repair. It showed safety and efficacy in reducing postoperative renal dysfunction compared with standard crystalloid solutions. These findings corroborate the use of Custodiol not only in TAAA patients, but also in other cases that require suprarenal clamping, including juxtarenal and pararenal aneurysms, or in further cases of renal surgery.
