INTRODUCTION: The aim of the study was to investigate the effect of neutrophil lymphocyte (NLR) and platelet lymphocyte
ratio (PLR) on prognosis in acute ischemic stroke (AIS) patients undergoing mechanical thrombectomy.
MATERIAL-METHOD: A retrospective study was made of the data of 56 patients aged 20-80 years who were diagnosed
with AIS and underwent mechanical thrombectomy. Thrombolysis in Brain Ischemia (TIBI) status was evaluated with
transcranial Doppler after treatment. The National Institutes of Health Stroke Scale (NIHHS) and modified Rankin
scale (mRS) were used to indicate neurological and functional deficits.
RESULTS: No difference was determined in the NLR and PLR between patients with or without middle cerebral artery
(MCA) occlusion, T and basilar occlusion. These ratios were also no different between the groups with different degrees
of recanalization. Platelet lymphocyte ratio was lower in patients with a dramatic improvement at the 24th hour (p=0.046).
Neutrophil lymphocyte ratio was higher in patients with symptomatic hemorrhage (p=0.046).
CONCLUSION: Although no relationship with outcome has yet been shown, the association with hemorrhagic change and
the recovery parameters at the 24th hour may enable NLR and PLR to be used as significant prognostic factors in patients
with acute ischemic stroke undergoing mechanical thrombectomy. Further studies are needed.
