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

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 x albumin x 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.
