Abstract

Objectives: In this study, we aimed to analyze the effect of the platelet-to-lymphocyte ratio (PLR) and neutrophil-to-lymphocyte ratio
(NLR) on prognosis during one-year follow-up after carotid endarterectomy surgery.
Patients and methods: Between October 2012 and December 2019, a total of 250 patients (176 males, 74 females; mean age: 67.7±8.8 years;
range, 47 to 94 years) with isolated carotid artery endarterectomies were retrospectively analyzed. All patients’ data were obtained from the
hospital information management system and hospital archive. The patients were divided into two groups (Group 1, n=232 and Group 2,
n=18) according to the one-year mortality rate and the risk factors were analyzed.
Results: During follow-up, the one-year mortality and one-year no mortality groups were compared. Univariate model revealed that there
were statistically significant differences between the groups regarding congestive heart failure, platelet count, NLR, and neurological
complications (p
