Abstract
Objective: To explore the effect of baseline Systemic Inflammatory Response reflected by platelet-to-lymphocyte ratio (PLR) and pre-thrombectomy cerebral edema reflected by Net Water Uptake (NWU) on futile recanalization in patients with Acute Ischemic Stroke (AIS) after successful thrombectomy, and to investigate the potential mediating role of baseline cerebral edema.
Methods: 134 Patients with anterior circulation ischemic stroke receiving successful thrombectomy were retrospectively studied. Their demographic and clinical characteristics were collected at admission, and the NWU was quantitatively calculated based on baseline computed tomography (CT). The predictive value of PLR for futile recanalization and the relationship between PLR, NWU, and futile recanalization using mediation analysis were explored. Patients were followed up for 90 days and were divided into a futile recanalization group and a favorable prognosis group [90-day modified Rankin Scale score of 0-2].
Results: High baseline PLR, NWU, no first-pass reperfusion, and large baseline ischemic core volume were independent predictors of futile recanalization after successful thrombectomy in patients with AIS. Mediation analysis results indicate that PLR may partially mediate the occurrence of futile recanalization through NWU.
Conclusion: Baseline PLR and NWU were independent predictors of futile recanalization, and higher PLR and NWU values were associated with a higher likelihood of futile recanalization. The findings suggest that early cerebral edema reflected by a high NWU value may be a mediator of PLR-affecting prognosis.
