Evaluation of mid-term results in our patients treated with N-Butyl cyanoacrylate embolization in saphenous vein insufficiency

Aim: The aim of this study is to present our mid-term results obtained from patients with advanced saphenous vein insufficiency treated with N-butyl cyanoacrylate embolization (CAE). Material and Methods: In the present study, we included 1013 patients who were treated with CAE because of moderate and severe saphenous vein insufficiency in Eskişehir Osmangazi University Medical Faculty Hospital Cardiovascular Surgery Clinic between January 2015 and November 2019. The patients were rechecked at 1st, 6th, 12th, 24th and 36th months. Venous Clinical Severity Score (VCSS) and Aberdeen Varicose Vein Questionnaire (AVVQ) results recorded at preoperative and postoperativee period. Doppler ultrasonography (USG) was performed to all patients in all controls. The absence of re-canalized flow in Doppler USG was accepted as the success of the procedure. Results: The mean age of 1013 patients was 51.27±14.30 years (448 men (44.2%) and 565 women (55.8%)). The average procedure time was 12.4±2.1 minutes, the average amount of CA used in the procedure was 1.6 ml (min: 1 ml - max: 2ml). In outpatient controls, complication rates was low, thrombophlebitis occurred in 17 patients (1.7%) and ecchymosis occurred in 9 patients (0.9%). The occlusion rate was 97.6% according to the 1-year follow-up results and 93.3% according to the 3-year follow-up results. The decrease in VCSS and AVVQ scores was statistically significant when the preoperative and postoperative period results compared (p<.05). Conclusion: In the present study, we think that CAE is a safely and effective treatment method for saphenous vein insufficiency. It has low complication, high occlusion rates and provides better comfort to the patients.
