The Incidence and Risk Factors of Deep Vein Thrombosis in Colorectal CancerPatients During the Perioperative Period

Abstract

[Purpose] The aim of this study was to investigate the incidence and risk factors of deep vein thrombosis (DVT) in colorectal cancer patients during the perioperative period. [Methods] We retrospectively reviewed 114 patients, who had undergone colorectal surgery at Kanazawa University Hospital between September 2010 and August 2013. The assessment of DVT in the lower extremities was performed using ultrasonography. [Result] The incidence of DVT in the perioperative period was 26.3%. The incidence of DVT before and after surgery was 18.4% and 23.7%, respectively. The significant variables identified by multivariate analyses were sex and previous venous thromboembolism (VTE) as an independent risk factor of preoperative DVT. The significant variables during the postoperative period were organ/space surgical site infection (SSI) and DVT diagnosed preoperatively as an independent risk factor of postoperative DVT. [Conclusion] We should perform screening for DVT during the perioperative period for colorectal cancer patients having several risk factors.
