BACKGROUND: The aim of this study was to retrospectively analyze the risk factors for venous thromboembolism (VTE) in gynecological patients and verify the validity of a fast-rating assessment table.
MATERIAL AND METHODS: From October 2015 to October 2017, 53 patients complicated with VTE after gynecological operations were analyzed, and a total of 106 patients with 2 adjacent operations were selected as the control group. Factors such as age, body mass index (BMI), and tumor type were analyzed by univariate and multivariate analysis. A fast-rating assessment table of VTE risk factors was constructed. This fast-rating assessment table and the Caprini score table were used to compare the scores of all patients.
RESULTS: In the univariate analysis, there were significant differences in BMI, tumor type, operation duration, blood loss, blood transfusion, bed rest time, and thrombus-related history between the 2 groups. In the multiple factor analysis, age >60 years old, BMI >28 kg/m², malignant tumors, operation duration ≥3 hours, laparoscopic surgery and thrombus-related history were independent risk factors for VTE in patients. Both the fast-rating assessment table and the Caprini score table identified 90% of VTE patients as high-risk and very high-risk, and there was no significant difference between the tables.
CONCLUSIONS: Patients with older age, high BMI, malignant tumors, longer operation duration, laparoscopic surgery, or history of thrombosis may be more prone to VTE after gynecologic surgery. The fast-rating assessment table is easy to operate and has a high recognition level for VTE. It can be applied widely.
