Incidence of and risk factors for preoperative deep venous thrombosis in patients undergoing gastric cancer surgery

摘要

Background Pulmonary thromboembolism (PE) is one of the life-threatening complications of gastric cancer surgery. D-dimer assay is a safe and rapid tool to exclude the presence of deep venous thrombosis (DVT). In July 2012, we started preoperative DVT screening of patients scheduled for gastric cancer surgery using a combination of D-dimer measurements and lower extremity venous ultrasonography to prevent PE.
