Background:
Elevation of activation markers of blood coagulation (thrombin-antithrombin complex [TAT], prothrombin fragment 1 + 2 [F1 + 2], D-Dimer] has not only been found in clinically overt thrombosis but also reflects a prethrombotic state.
Objective:
The purpose of our study was to evaluate whether varicose vein stripping, an operative procedure with an extremely low risk of postoperative thromboembolism, induces a prethrombotic state by activation of the hemostatic system.
Methods:
In a prospective, observational study we compared the baseline and postoperative values of TAT, F1 + 2, and D-Dimers in 15 patients undergoing varicose vein stripping and in 11 control patients undergoing surgical procedures associated with only minor soft tissue trauma.
Results:
A highly significant postoperative elevation of TAT (P < 0.001), F1 + 2 (P = 0.006), and D-Dimer (P < 0.001) was observed in the varicose vein stripping group. No significant postoperative change of the respective parameters was detected in the control group.
Conclusion:
We therefore conclude that varicose vein stripping induces a significant hemostatic system activation although postoperative thrombotic events are rare.
