ABSTRACT
Objective:
To investigate the risk factors of portal vein system thrombosis (PVST) after portoazygous devascularization in patients with portal hypertension.Methods:
Clinical data of 215 patients with portal hypertension treated by splenectomy at the Department of Hepatobiliary Surgery, the First Affiliated Hospital of Xi′an Jiaotong University from Jan 2012 to Dec 2017 were retrospectively analyzed. Univariate analysis of variance and Logistic regression were used to analyze the clinical risk factors that may lead to PVST.Results:
The incidence of PVST was 43.7%(94/215). Univariate analysis of variance showed that the diameter of portal vein, the diameter of splenic vein, the thickness of spleen, laparoscopic or open surgery, and postoperative platelet count were correlated with postoperative PVST (all P<0.05). Logistic regression analysis showed that splenic vein diameter ( OR=3.137, 95% CI 1.391-7.076, P=0.006), splenic thickness ( OR=3.065, 95% CI 1.418-6.626, P=0.004) and postoperative platelet count ( OR=7.446, 95% CI 3.057-18.137, P=0.000) were independent risk factors for PVST in patients with portal hypertension.Conclusion:
Postoperative PVST in patients with portal hypertension are more likely to develope when preoperative splenic vein ≥11 mm, splenic thickness ≥60 mm and platelet count ≥300×10 9/L on the 7th day after operation.
