Can HALP score predict post-contrast acute kidney injury and 6-year mortality in patients undergoing endovascular abdominal aneurysm repair?

Abstract

Background The aim of this study is to investigate the relationship between HALP score and post-contrast acute kidney injury (PC-AKI) and average 6-year mortality in patients undergoing endovascular abdominal aortic aneurysm repair (EVAR). Methods 125 patients who underwent EVAR between January 2015 and December 2020 were included in our study. HALP score was calculated with the formula “hemoglobin × albumin × lymphocyte count/platelet count.” In the first phase of the study, two groups were developed: those who developed PC-AKI and those who did not. In the second stage, statistical analysis was performed by creating two groups: average 6-year mortality and survivors group. Results HALP score was found to be lower in the PC-AKI group [26.12 (14–61.54) versus 40.53 (7.22–103.61); p < .001]. Low HALP score was found to be both a dependent and independent predictor of the development of PC-AKI ( p = .019). HALP score was also found to be lower in the mortality group compared to the survivors [28.97 (12.6–103.61) versus 40.81 (7.22-99) p = .004]. Low HALP score was found to be only a dependent predictor of mortality. The development of PC-AKI was found to be an independent predictor of mortality ( p = .042). Conclusions The HALP score, which can be calculated with a simple formula, can be used to predict PC-AKI and medium-long-term mortality in EVAR patients.
