Objective:

The objective of the study was to compare the prevalence of endovenous heat-induced thrombosis (EHIT) in thromboprophylaxis with rivaroxaban versus none thromboprophylaxis in ablation with radiofrequency (RF) ablation.

Methods:

A retrospective, observational design of cases and controls of patients with chronic venous insufficiency was reviewed after the procedure of truncal ablation with RF. Group 1 did not receive thromboprophylaxis after the surgery. Group 2 received 10 mg of rivaroxaban every 24 h for a 2-week period. The presence of EHIT was evaluated during the 3rd and 7th days of post-surgery.

Results:

Between January 2013 and December 2017, a total of 113 patients were evaluated with 132 procedures. As a result, we found a significant difference in the total of procedures in favor of thromboprophylaxis with rivaroxaban decreasing the EHIT by p ≤ 0.0031 and odds ratio 8.5 with a confidence interval of 95% (2.10-39.9).

Conclusion:

The use of rivaroxaban was effective in the thromboprophylaxis of EHIT in the venous ablation with RF.
