Admission Neutrophil-Lymphocyte Ratio Predicts Rebleeding Following Aneurismal Subarachnoid Hemorrhage.

Objective: The relationship between neutrophil-lymphocyte ratio (NLR) and the occurrence of rebleeding in aneurysmal subarachnoid hemorrhage (aSAH) is poorly understood. Our study aimed to investigate the association between NLR on admission and rebleeding following aSAH.

Methods: Clinical and laboratorial data from patients with aSAH were retrospectively collected, including leukocyte, neutrophil, lymphocyte, and NLR.
