Diagnosis of recurrent reflux within the remnant non-treatment stump after bilateral cyanoacrylate ablation of the great saphenous veins

Cyanoacrylate ablation, along with mechanochemical ablation, is one of the best-known non-thermal ablation treatment methods for superficial venous reflux. Cyanoacrylate ablation is comparable to thermal ablation in terms of efficacy and safety, and offers the benefit of not requiring tumescent injections and the use of compression stockings. Here, we report about a patient who developed recurrent reflux in the residual stump after cyanoacrylate ablation. As a refluxing long residual stump can be a risk factor for late recurrence, improvements are needed to make the protocol more refined, including leaving the stump as short as possible.
