A Study of Initiation Timing of VTE Prevention After Colorectal Cancer Surgery

This project intends to conduct a single-center, prospective, observational cohort study to explore the impact of the timing of drug prophylaxis on the risk of postoperative bleeding and the preventive effect of VTE in the prevention and management of postoperative venous thromboembolism (VTE) after colorectal cancer (CRC) surgery in Chinese population, and to determine its application and promotion value. The research results of this project can provide useful reference for optimizing the prevention and management of VTE after CRC operation.
