Predictive Role of Neutrophil-to-Platelet Ratio in Futile Recanalization of Patients After Endovascular Therapy

Abstract

Aim:

To explore the association between the neutrophil-to-platelet ratio (NPR) and futile recanalization (FR) in patients with acute ischemic stroke due to large vascular occlusions after endovascular therapy (EVT).

Methods:

FR after EVT was defined as a poor 90-day prognosis (modified Rankin scale [mRS] score ≥3) despite successful reperfusion (modified thrombolysis in cerebral infarction grade 2b–3). Patients were divided into high NPR (>35; n = 115) and low NPR (≤35; n = 81) groups.

Results:

The FR rate was significantly higher in the high NPR group than low NPR group (81.74 vs 55.56%; p = 0.000). NPR was independently associated with FR (odds ratio: 2.107; 95% CI: 1.017–4.364; p = 0.045).

Conclusion:

High NPR was associated with the risk of FR in patients with acute ischemic stroke due to large vascular occlusions.
