Approach to tortuous vena saphena magna with insufficiency: Foam scleroterapy.

Objective: This study aimed to investigate the efficacy of foam sclerotherapy in the treatment of tortuous Great Saphenous Vein (GSV) insufficiency.

Methods: In this prospective non-randomized study 62 patients with tortuous GSV insufficiency were included. All patients were delivered sclerosant agent in the form of foam into the GSV through a cannula above the knee level. Characteristics of patients, diameter of veins, reflux grades, Venous Clinical Severity Score (VCSS) and Clinical, Etiological, Anatomical, Pathological (CEAP) scores, concentration of sclerosant agent, complications and follow-up results were recorded.

Results: Foam sclerotheraphy was performed with 100% technical success in all patients at operative room. There were no allergic reactions or neurological complications during and after the operations. Ecchymosis was the most common complication with 37.1% frequency. . VCSS scores significantly decreased from 6.43% to 2.53%, during follow-up from initial admission to sixth months, respectively (<0.05).In the first month parameters, successful occlusion rate was 88.7%, whereas its rate was 82.3% in sixth month. Recanalization rate significantly increased from 11.3% to 17.7% during follow-up from first to sixth months, respectively (<0.05).

Conclusions: Due to its low complication rate, low cost, acceptable total occlusion rate and reproducibility; Foam sclerotherapy can be considered a reliable treatment for patients with tortuous GSV insufficiency.
