Abstract
Background
There is a risk of hypoperfusion during kidney transplantation surgery owing to patients’ underlying disease and ischemia-reperfusion injury; further, hypoperfusion may cause injury to major organs. We hypothesized that the decrease in blood pressure after ischemia-reperfusion injury during kidney transplantation may be associated with indicators of liver injury and kidney graft function.
Methods
Data regarding living-donor kidney transplantations performed at our institution between 2018 and 2022 were retrospectively evaluated. Exclusion criteria included pediatric recipients or donors aged <18 years, multiple organ transplantation, and elevated postoperative serum transaminase levels. Correlations among blood pressure, serum transaminase levels on postoperative days 3 to 5, and estimated glomerular filtration rate (eGFR) on postoperative days 7 and 14 were analyzed. Further, a subgroup analysis was performed based on eGFR.
Results
A total of 276 patients were included in the final analysis. Serum transaminase levels were significantly negatively correlated with eGFR (partial correlation coefficient—0.26, P < .001). The postreperfusion decrease in blood pressure was not correlated with serum transaminase levels. However, the postreperfusion decrease in blood pressure and baseline blood pressure correlated with the eGFR (partial correlation coefficient = −0.18, P = .004).
Conclusion
These findings indicate a correlation between intraoperative liver injury and kidney graft function, suggesting the importance of intraoperative management of organ perfusion. Since postreperfusion blood pressure changes did not significantly correlate with liver injury indicators, it is important to consider other causative factors for hypoperfusion in major organs during living-donor kidney transplantation, including microcirculatory failure and organ congestion-related ischemia/reperfusion.
期刊介绍：
Transplantation Proceedings publishes several different categories of manuscripts, all of which undergo extensive peer review by recognized authorities in the field prior to their acceptance for publication.
The first type of manuscripts consists of sets of papers providing an in-depth expression of the current state of the art in various rapidly developing components of world transplantation biology and medicine. These manuscripts emanate from congresses of the affiliated transplantation societies, from Symposia sponsored by the Societies, as well as special Conferences and Workshops covering related topics.
Transplantation Proceedings also publishes several special sections including publication of Clinical Transplantation Proceedings, being rapid original contributions of preclinical and clinical experiences. These manuscripts undergo review by members of the Editorial Board.
Original basic or clinical science articles, clinical trials and case studies can be submitted to the journal?s open access companion title Transplantation Reports.
