Portal vein thrombosis (PVT) following hepatectomy is potentially life-threatening. We aimed to evaluate the incidence of PVT after hepatectomy for hepatocellular carcinoma and identify coagulation and fibrinolytic factors that could predict early-stage postoperative PVT.A retrospective analysis was conducted on 65 hepatocellular carcinoma patients who underwent radical hepatectomy. The risk factors for postoperative PVT were identified based on univariate and multivariate analyses, and the levels of coagulation and fibrinolytic factors were measured during the perioperative period.The incidence of PVT after hepatectomy was 20.0%. The patients were divided into two groups: those with PVT (n=13; PVT group) and those without PVT (n=52; no-PVT group). The frequency of the use of the Pringle maneuver during surgery was higher in the PVT group than in the no-PVT group, and the postoperative/preoperative ratios of thrombin-antithrombin III complex (TAT) and of D-dimer were significantly higher in the PVT group.A high incidence of PVT was found in hepatocellular carcinoma patients after hepatectomy. The frequency of the Pringle maneuver is a potential risk factor for postoperative PVT, and the postoperative/preoperative TAT and D-dimer ratios may be used as early predictors of PVT after hepatectomy for hepatocellular carcinoma.
