â¢Anticoagulant drug significantly decreased the incidence rate of PVST after LS.â¢We found that PVST was related to many risk factors.â¢The anticoagulant drug was an independent protective factor for PVST.
BackgroundAfter laparoscopic splenectomy (LS) in patients with cirrhotic and hypersplenism, there is highly risk of suffering from portal vein system thrombosis (PVST) complication. This study is aimed to investigate the risk factors of PVST and study the anticoagulation effect on the prevention of PVST after LS.Materials and methodsWe retrospectively observed 130 patients who performed LS from February 2009 to December 2016. Patients were classified into the anticoagulation group (73 patients) and the non-anticoagulation group (57 patients). At the same time, the non-PVST and PVST groups were used to analyze the factors of thrombosis.ResultsWe analyzed the risk factors of PVST, the mean platelet volume (MPV), platelet count (PLT), plasma d-dimer, thickness of spleen and portal vein diameter were statistically significant (PÂ <Â 0.05) between PVST group and non-PVST group. Compared with the non-anticoagulant group, anticoagulant group had a lower incidence of PVST (PÂ =Â 0.044), a significant lower PLT (PÂ =Â 0.001), a notable lower mean platelet volume (PÂ =Â 0.006), and an obvious lower d-dimer (PÂ =Â 0.001) after LS. And prothrombin time (PT) and international normalized ratio (INR) were significant increase after treated with anticoagulant drugs. Multiple logistic regression analysis reported that PLT, d-dimer, portal vein diameter and thickness of spleen were the risk factors of PVST, however the anticoagulant drug was an independent protective factor for PVST (PÂ =Â 0.001).ConclusionsAnticoagulant drug significantly decreased the incidence rate of PVST in patients with cirrhotic and portal hypertension after LS.
