Purpose: The aim of this retrospective single-center study is to describe and analyze short-, mid-, and long-term risk factors for great saphenous vein (GSV) recanalization after endovenous radiofrequency ablation (RFA). Materials and methods: All consecutive patients with GSV incompetence and varicose veins underwent RFA were enrolled between 2009 and 2018. Data on demographic, pre- and postoperative color Doppler scan (CDUS) findings, perioperative complications, and follow-up were prospectively collected. Primary outcome was GSV recanalization rate at 1 week after RFA. Secondary outcomes were postoperative complication rate, as well as GSV recanalization rate at 1, 3, and 5 years after RFA. Risk factors for recanalization were also analyzed, for each follow-up assessment, identifying differences in recanalized (Rec) and non-recanalized (nRec) groups. Results: During the study period, 1297 patients were treated. Among these, 1265 had at least 1 week of follow-up. Mean follow-up time was 3.0 ± 1.9 years. Recanalization rate at 1 week, 1, 3, and 5 years was 2.4%, 4.3%, 9.3%, and 17.5%, respectively. After multivariate analysis for each follow-up evaluation, CEAP classes C4 and 5, as well as preoperative GSV diameter >6 mm and history of smoking were found to be independent predictors of recanalization. Furthermore, age >61 years and postoperative complications such as pigmentation, edema, and paresthesia were found to be dependent risk factors. Conclusion: RFA remains a safe and durable technique to ablate incompetent GSV. Despite this, particular attention should be paid to patients with high CEAP classes to avoid short and long-term recanalization.

Abstract

Purpose: The aim of this retrospective single-center study is to describe and analyze short-, mid-, and long-term risk factors for great saphenous vein (GSV) recanalization after endovenous radiofrequency ablation (RFA). Materials and methods: All consecutive patients with GSV incompetence and varicose veins underwent RFA were enrolled between 2009 and 2018. Data on demographic, pre- and postoperative color Doppler scan (CDUS) findings, perioperative complications, and follow-up were prospectively collected. Primary outcome was GSV recanalization rate at 1 week after RFA. Secondary outcomes were postoperative complication rate, as well as GSV recanalization rate at 1, 3, and 5 years after RFA. Risk factors for recanalization were also analyzed, for each follow-up assessment, identifying differences in recanalized (Rec) and non-recanalized (nRec) groups. Results: During the study period, 1297 patients were treated. Among these, 1265 had at least 1 week of follow-up. Mean follow-up time was 3.0 ± 1.9 years. Recanalization rate at 1 week, 1, 3, and 5 years was 2.4%, 4.3%, 9.3%, and 17.5%, respectively. After multivariate analysis for each follow-up evaluation, CEAP classes C4 and 5, as well as preoperative GSV diameter >6 mm and history of smoking were found to be independent predictors of recanalization. Furthermore, age >61 years and postoperative complications such as pigmentation, edema, and paresthesia were found to be dependent risk factors. Conclusion: RFA remains a safe and durable technique to ablate incompetent GSV. Despite this, particular attention should be paid to patients with high CEAP classes to avoid short and long-term recanalization.
