Background There have been well-documented implications of race/ethnicity on the outcome of various vascular diseases, yet there are limited data on risk factors and outcome of lower limb swelling. While many patients improve with endovenous therapy (thermal ablation or iliac vein stenting), some patients' symptoms persist. The goal of this study was to identify clinical factors including race/ethnicity related to persistent leg swelling after treatment with both iliac vein stenting and thermal ablation. Methods From February 2012 to February 2014, this observational study analyzed data for 173 patients with chronic venous insufficiency who underwent both iliac vein stent placement as well as thermal ablation (radiofrequency ablation or endovenous laser ablation). All procedures of the thermal ablations and the iliac vein stenting were staged. Iliac vein stenosis was identified using intravascular ultrasound of the iliofemoral venous segment showing >50% cross-sectional area or diameter reduction. The patients were queried to the resolution of their leg swelling after both procedures were performed. The resolution of swelling was correlated with age, gender, presenting sign according to CEAP classification, race/ethnicity and degree of iliac vein stenosis. Patients were categorized by Caucasians ( n = 97), African Americans ( n = 27), or Hispanics ( n = 49). Statistical analysis performed using Chi-square and Student's t test. Results Of the total 173 patients who underwent both endovenous closure and iliac vein stent placements, 117 (67.6%) patients were women. The average age was 67 (±13 SD) years. The average pain score was 2.9(±3.1 SD). The average degree of iliac vein stenosis was 66.5(±13.3 SD). About 56.1% were Caucasians, 15.6% were African Americans, and 28.3% were Hispanics. The number of patients with iliac vein stent thrombosis was 2. One hundred fifty-two (87.9%) patients stated that they had improvement in swelling after combined procedures, 100 (65.8%) patients were women. The average age was 67.3 (±13 SD) years. The average pain score was 2.9 (±3.1 SD). The average degree of iliac vein stenosis was 67.3% (±12.8 SD). About 56.6% were Caucasians, 15.1% were African Americans, and 28.3% were Hispanics. The number of patients with iliac vein stent thrombosis was 1. Twenty-one (12.1%) patients stated they had no improvement after both procedures. Correlating these group factors with the group of patients who improved their swelling after the combined procedures we found the following: 17 (81%) of these patients were females ( P=0.16). The average age was 68.4 (±17 SD) years ( P=0.72 SD). The average pain score was 3.2 (±3.7 SD) ( P=0.68). The average degree of iliac vein stenosis was 60.2% (±15.9 SD) ( P=0.02). Around 52.4% were Caucasians, 19% were African Americans, and 28.6% were Hispanics ( P=0.88). The number of patients with iliac vein stent thrombosis was 1 ( P = 0.1). Conclusion These data suggest that the clinical factors including race are not clinically significant factors in the response to...

Objective: Endovenous thermal ablation has become the procedure of choice in the treatment of superficial venous reflux disease. The current armamentarium of devices and techniques aimed at the elimination of saphenous reflux offers surgeons and interventionalists a variety of treatment options; however, there is a lack of data comparing the safety of these products. The most concerning complication after endovenous thermal ablation is endothermal heat-induced thrombosis (EHIT) because of the risk of progression to deep venous thrombosis. This study aimed to compare the incidence rate of EHIT between radiofrequency ablation (RFA) and endovenous laser therapy (EVLT).Methods: This was a single-center, office-based, retrospective study during the course of 5 years, in which 3218 consecutive patients underwent 10,029 endovenous saphenous ablations. The patient cohort was 66.2% female, with an average age of 61.9 years. At the time of each indi-
