INTRODUCTION: Endothermal heat-induced thrombosis (EHIT) is a known complication of saphenous vein ablation. We reviewed our experience with patients undergoing ablation of their varicose veins. METHODS: We performed a retrospective analysis of a prospec-tively collected database using the Vascular Quality Initiative Varicose Vein Registry. All endovenous ablation procedures performed at our tertiary care referral center between January 2015 and December 2016 were analyzed. Data collected included patients demographics, comorbidities, procedural details, and complica-tions. Data analysis was conducted on SPSS 22.0 (SPSS Inc). RESULTS: Among a total of 680 endovenous ablation procedures, the mean age was 58 years, and females comprised 73% of the cohort. EHIT occurred in 4.1% (28 vein ablation procedures), 28.6% of these were class 3 or 4 EHITs, and the rest were either class 1 or 2. Method of ablation did not affect EHIT rates (3.9% for radiofrequency ablation vs 4.3% for laser ablation, p = 0.173). Variables including BMI, number of pregnancies, history of deep vein thrombosis, status of anticoagulation, and CEAP class were not associated with increased EHIT rates. CONCLUSIONS: In our cohort, there was no difference in incidence rate of EHIT between ablation with radiofrequency vs laser.
