ABSTRACT
@#Objective To study the correlation of preoperative hemoglobin amount with venous thromboembolism (VTE) after surgical treatment of bronchiectasis and the clinical significance. Methods A retrospective study was performed on patients with bronchiectasis who underwent surgical treatment in our center from June 2017 to November 2021. The differences in blood parameters between the VTE patients and non-VTE patients were compared. The relationship between preoperative hemoglobin and VTE was confirmed by quartile grouping and receiver operating characteristic (ROC) curve. Results A total of 122 patients were enrolled, including 50 males and 72 females, with a mean age of 52.52±12.29 years. The overall incidence of VTE after bronchiectasis was 9.02% (11/122). Preoperative hemoglobin amount (OR=0.923, 95%CI 0.870-0.980, P=0.008) and D-dimer amount (OR=1.734, 95%CI 1.087-2.766, P=0.021) were independent influencing factors for VTE after bronchiectasis. The incidence of VTE after bronchiectasis decreased gradually with the increase of preoperative hemoglobin amount. The area under the ROC curve (AUC) of postoperative D-dimer alone was 0.757, whereas the AUC of postoperative D-dimer combined with preoperative hemoglobin amount was 0.878. Conclusion Low preoperative hemoglobin is an independent risk factor for postoperative VTE. Postoperative D-dimer combined with preoperative hemoglobin amount has a better predictive performance compared with postoperative D-dimer alone for postoperative VTE.
ABSTRACT
The risk of perioperative venous thromboembolism (VTE) is pretty high in thoracic cancer patients. Perioperative VTE influences the recovery of patients after operation and quality of life in the future, even seriously leading to death. To strengthen the knowledge and attention of thoracic surgeons on perioperative VTE in thoracic cancer patients, China National Research Collaborative Group on VTE in Thoracic Surgery released the edition of VTE prophalaxis in thoracic cancer patients: Chinese experts consensus in 2018. This article is to interpret the diagnostic value and risk prediction value of D-dimer in VTE in detail, and briefly introduce the role of other biomarkers in VTE of tumor patients. The consensus interpretation aims to deepen the understanding of thoracic surgeons on the clinical significance of D-dimer in VTE.
