The relationship of platelet-to-lymphocyte ratio with clinical outcome and final infarct core in acute ischemic stroke patients who have undergone endovascular therapy.

In this study we aimed to evaluate whether the PLR had a prognostic role in stroke patients undergoing thrombectomy and attempted to determine the effect that this ratio had on their survival. METHODS: Over a three-year period, demographic, clinical, and angiographic findings of 57 consecutive patients with acute ischemic stroke who underwent mechanical thrombectomy were evaluated. RESULTS: The patients were divided into two groups on the basis of a PLR level cut-off value of 145 based on receiver operating characteristic (ROC) curve. Successful revascularization (mTICI 2b and 3) was achieved in 42 of 57 (73.7%) patients; a mTICI 3 state was observed in 21 of 23 patients with low-PLR values (p = .015). Patients with higher PLR values had significantly a score of less than six on the ASPECT scale compared to patients with lower PLR values (p = .005). The patients with low-PLR values had better functional outcomes (mRS ≤ 2) compared with the patients with high-PLR values [respectively, p = .004 (at first month) and p = .014 (at third month)]. DISCUSSION: The platelet-to-lymphocyte ratio could represent pro-thrombotic inflammatory state in acute ischemic stroke patients because having a high-PLR values increased the poor prognosis, the rate of insufficient recanalization, and the size of infarcted area.
