This study aimed to investigate the association of white blood cell (WBC) count and neutrophil-to-lymphocyte ratio (NLR) with the occurrence of DCI in SAH patients.Methods: A total of 122 patients diagnosed with aSAH within 72 h of onset were retrospectively enrolled. The count of WBC, neutrophil count (NC), and lymphocyte (LC) was collected on admission. Computed tomography perfusion was performed within 7 days after SAH. The occurrence of DCI was recorded during the hospitalization.Results: Among enrolled patients, 43 (35.2%) developed DCI during hospitalization. Patients who developed DCI had a higher count of WBC, NC, and NLR as well as a lower count of LC. NC and NLR were independently associated with the occurrence of DCI, while NLR was the best predictive parameter according to the receiver operating characteristic curve. Moreover, there was a strong correlation between NLR and mean cerebral blood flow, mean transit time and mean time to peak.Conclusion: Leukocytosis is an early pathology of SAH, and NLR may be a practical predictor for the occurrence of DCI in SAH patients.Keywords: aneurismal subarachnoid hemorrhage, neutrophil-to-lymphocyte ratio, cerebral blood flow, delayed cerebral ischemiaWu YHe QWei YZhu JHe ZZhang XDGuo ZDXu RCheng CHuang ZSun XCDove Medical Pressarticleaneurismal subarachnoid hemorrhageneutrophil-to-lymphocyte ratiocerebral blood flowdelayed cerebral ischemiaNeurosciences.
