VP35 Effectiveness and Safety of Cyanoacrylate Ablation for Varicose Veins

Published online by Cambridge University Press:  31 December 2019

Abstract

Introduction

Treatment of varicose veins is currently performed by different interventionist alternatives that include surgical, endothermal and non-thermal ablation therapies. The main guidelines recommended endovenous thermal treatment as the first choice therapy; however present side effects related to thermal energy. Non-tumescent endovenous ablation techniques such as cyanoacrylate ablation (CA) started to develop to avoid these problems. The objective of this study is to assess the effectiveness and safety of CA for saphenous vein incompetence.

Methods

A systematic review with meta-analysis was carried out. The search of scientific literature was performed in Medline, Embase, Cochrane library, CDR, WoS and Scopus databases. GRADE methodology was used to assess the quality of the evidence and Cochrane risk of bias tool to assess methodological quality of randomized control trials (RCT). Pooled risk ratio was calculated using a random effects model.

Results

Two RCTs and one non-RCT comprising 1,077 participants were included. Additionally, 10 case series were included for safety assessment. Pooled analysis of closure rates by the two RCTs indicated there were not significant differences between CA and radiofrequency ablation (RFA) or endovenous laser ablation (EVLA). Improvements in venous clinical severity score were reported by all comparative studies without significant differences among groups. The most frequently reported adverse events were ecchymosis, phlebitis, paraesthesia, and thrombosis. The pooled analysis showed significant differences only in ecchymosis rates, with lower probability of ecchymosis in CA groups. CA treatment showed lower pain rates and shorter intervention times and recovery compared to endothermal therapies.

Conclusions

The effectiveness of CA devices in the treatment of varicose veins is comparable to EVLA and RFA, while the rates of adverse effects are lower. Despite the limitations of the evidence, CA may be a promising alternative to existing treatments, with the advantages of better patient comfort.
