摘要：The aim was to evaluate the efficacy and safety of different combination strategies for prophylaxis of venous thromboembolism (VTE) after gynecologic surgery in patients at different levels of risk. This was a prospective multicenter randomized controlled study, in which 625 women who would undergo pelvic surgery for gynecologic diseases were stratified into three risk groups and then randomized into four groups to receive graduated compression stockings (GCS) alone (group A), GCS + low molecular weight heparin (LMWH) (group B), GCS + intermittent pneumatic compression (IPC) (group C), and GCS + IPC + LMWH (group C), respectively. The overall incidence of DVT was 5.1%. Group A had the highest incidence of DVT (8.8%), followed by group C (5.2%), group B (3.8%), and group D (2.6%). There was a significant difference in the incidence of DVT between groups A and D. The incidence of DVT was significantly lower in LMWH-treated patients (group B + group D) than in non-LMWH-treated patients (group A + group C). In conclusion, combination prophylaxis, especially LMWH-containing strategies, is better than monoprophylaxis in reducing VTE after gynecologic surgery. Risk-stratified prophylactic strategies should be implemented in patients undergoing gynecologic surgery, with LMWH-containing strategies being recommended for high-risk and very-high-risk patients.
