Predictive Value of Inflammation Biomarkers in Patients with Portal Vein Thrombosis.

Abstract

Background and AimsTo investigate the usefulness of inflammation biomarkers to serve as a predictors of portal vein thrombosis (PVT) postoperatively (post) in patients with portal hypertension after splenectomy and periesophagogastric devascularization.MethodsA total of 177 liver cirrhosis patients were recruited from January 2013 to December 2017. They were divided into a PVT group (n=71) and a non-PVT group (n=106), according to ultrasound examination findings at 7-day post. Inflammation biomarkers involving platelet-to-lymphocyte ratio (PLR), neutrophil-to-lymphocyte ratio (NLR), monocyte-to-lymphocyte ratio (MLR), red blood cell distribution width-to-platelet ratio(RPR), mean platelet volume-to-platelet ratio (MPR) preoperatively (pre) and at 1, 3, 7-days post were recorded.ResultsThe univariate logistic regression analysis indicated that PLR (pre) (odds ratio (OR)=3.963, 95% confidence interval (CI)=2.070–7.587, p<0.000), MLR (pre) (OR=2.760, 95% CI=1.386–5.497, p=0.004), PLR (post-day 7) (OR=3.345, 95% CI=1.767–6.332, p=0.000) were significantly associated with the presence of PVT. The multivariate logistic regression analysis results indicated that PLR (pre) (OR=3.037, 95% CI=1.463–6.305, p=0.003), MLR (pre) (OR=2.188, 95% CI=1.003–4.772, p=0.049), PLR(post-day 7) (OR=2.166, 95% CI=1.053–4.454, p=0.036) were independent factors for predicting PVT.ConclusionsThe PLR (pre), MLR (pre), and PLR (post-day 7) are predictors of portal vein thrombosis post in patients with portal hypertension after splenectomy and periesophagogastric devascularization.
