Prophylaxis for venous thromboembolism after resection of hepatocellular carcinoma on cirrhosis: Is it necessary?

Abstract

AIM: To assess the safety and effectiveness of prophylaxis for venous thromboembolism (VTE) in a large population of patients with hepatocellular carcinoma (HCC) on cirrhosis. METHODS: Two hundred and twenty nine consecutive cirrhotic patients with HCC who underwent hepatic resection were retrospectively evaluated to assess whether there was any difference in the incidence of thrombotic or hemorrhagic complications between those who received and those who did not receive prophylaxis with low-molecular weight heparin. Differences and possible effects of the following parameters were investigated: age, sex, Child-Pugh and model for end-stage liver disease (MELD) score, platelet count, presence of esophageal varices, type of hepatic resection, duration of surgery, intraoperative transfusion of blood and fresh frozen plasma (FFP), body mass index, diabetes and previous cardiovascular disease. RESULTS: One hundred and fifty seven of 229 (68.5%) patients received antithromboembolic prophylaxis (group A) whil
