IP271. Safety and Efficacy of Endovenous Ablations in Octogenarians, Nonagenarians, and Centenarians

Abstract Objective Endovenous ablation of the lower extremity veins has become the primary treatment of symptomatic venous reflux disease. Endovenous heat-induced thrombosis (EHIT) and recanalization are two well-known complications of these venous ablative procedures. Because the elderly represent the fastest growing demographic, our goal was to look at whether there is a difference of these complications and age distribution in octogenarians, nonagenarians, and centenariansvs the younger population. Methods A retrospective study was conducted of 10,029 procedures that were performed from March 2012 to September 2018 on 8273 veins across 3218 patients who underwent endovenous ablation for lower extremity venous reflux; 6091 procedures were performed with radiofrequency ablation, and 3938 were performed with endovenous laser ablation. We reviewed charts of all patients who underwent radiofrequency ablationor endovenous laser treatmentduring this time. Postprocedural venous duplex ultrasound was performed at 3 to 7 days to check for EHIT and recanalization, every 3 months for the first year, and every 6 to 12 months thereafter. The χ2 test and analysis of variance were used for statistical analysis. Results Ages ranged from 15 years to 103 years. The average age of the patients was 61.9 ± 15.2 years. Average overall follow-up for all age groups was 25.8 ± 12.9 months. Of the 3218 patients, 2700 were younger than 80 years, 380 were between 80 and 89 years, 132 were between 90 and 99 years, and 6 were 100 years or older. Of the 10,029 procedures, 8730 were performed on patients younger than 80 years; 1124, on patients 80 to 89 years; 159, on patients 90 to 99 years; and 16, on patients 100 years or older. There were 111 patients who had bilateral procedures in the accessory saphenous vein, 1878 patients who had bilateral procedures in the great saphenous vein, 99 patients who had bilateral procedures in the perforator vein, and 760 patients who had bilateral procedures in the small saphenous vein. There were statistically significant increases in EHIT rates between octogenarians and those in the age group Conclusions Whereas there is a relatively higher chance of EHIT and recanalization in the age group >80 years, our study shows that the majority of EHITs were class 1 and class 2. According to our study, venous ablation is safe and effective across all age groups, and age alone should not be used to deny patients venous ablations.
