ABSTRACT
INTRODUCTION:
The neutrophil to lymphocyte ratio (NLR) and the platelet to lymphocyte ratio (PLR) have been identified as predictive factors in several cardiovascular diseases but their significance in patients with internal carotid artery (ICA) stenosis is still poorly known. The aim of this study was to determine the clinical significance of the preoperative NLR and PLR in patients with ICA stenosis undergoing carotid endarterectomy. MATERIAL ANDMETHODS:
Consecutive patients who underwent carotid endarterectomy for ICA stenosis were retrospectively included (nâ¯=â¯270). The population was divided into 2 series of 4 groups based on the quartile values of the preoperative NLR and PLR group Ia (NLR < 1.5), IIa (1.50 < NLR < 2.07), IIIa (2.07 < NLR < 2.95), IVa (NLR>2.95), and group Ib (PLR < 86.6), IIb (86.6 < PLR < 111.7), IIIb (111.7 < PLR < 148.3), IVb (PLR > 148.3). Clinical characteristics and 30-day postoperative outcomes were compared among the groups.RESULTS:
One death (.4%) was reported during the 30-day postoperative period and the overall stroke and death rate was 1.5%. The proportion of patients with symptomatic ICA stenosis were significantly higher in group IVa compared to groups Ia, IIa, IIIa (64.2% vs 33.8%, 44.8% and 45.6%, respectively, Pâ¯=â¯.005), and higher in group IVb compared to groups Ib, IIb, IIIb (59.7% vs 47.1%, 35.8%, 45.6%, Pâ¯=â¯.051). No significant difference on 30-day postoperative all-cause complications was observed among the groups.CONCLUSIONS:
A high preoperative NLR and PLR is significantly associated with symptomatic ICA stenosis. Further studies are required to determine their interest as predictors of postoperative outcomes in patients undergoing carotid endarterectomy.Palavras-chave
