Can neutrophil-lymphocyte ratio be a predictor of cerebral vasospasm in patients with subarachnoid hemorrhage?

This study aimed to investigate the relationship between neutrophil-lymphocyte ratio (NLR) and development of vasospasm in patients with aneurysmal subarachnoid hemorrhage (SAH). Materials and Methods The study was performed by retrospectively analyzing the data of 170 aneurysmal SAH patients who admitted to the intensive care unit of our hospital between 2011 and 2017. We investigated the ability of NLR values calculated from the blood samples taken at the time of admission to predict for vasospasm. Results Thirty-five percent of the patients developed vasospasm. NLR values were associated with the development of vasospasm (OR 1.15; 95% confidence interval, 1.09-1.22; p
