Introduction. Over the past decade, thermal tumescent (TT) ablation became the “gold standard” treatment of varicose veins. Non-thermal non-tumescent (NTNT) methods emerged in response to minimize the interventional invasion.Aim. To evaluate the two-year results of cyanoacrylate adhesive closure (CAC).Methods. Between July 2019 and July 2021, CAC was performed in 457 patients (average age 57.8 ± 15.7 years), on 634 limbs and 725 saphenous veins. Patient distribution according to CEAP was: C2 – 38%; C3 – 37%; C4 – 19%; C5 – 4%; C6 – 2%. The inclusion criteria were: incompetence of sapheno-femoral/popliteal junction and axial reflux > 0.5 sec, diameter of saphenous trunk > 6 mm, presence of varicosities. CAC was performed according to the protocol of the American Vein Closure System In more than 2/3 of cases (76.2%), CAC was performed selectively without tributary treatment . The pain was assessed by visual-analogue scale (VAS). The control ultrasound was performed on the 3rd day, 1, 3, 6, and 12 months post-intervention.Results. Anatomical success was achieved in 100%. The VAS pain score was < 3 in 93% of patients. Partial recanalization occurred in 4 (0.6%) patients. Distal deep vein thrombosis was detected in 2 (0.3%) patients, migration of glue – in 7 (1%) patients, phlebitislike skin reaction – in 50 (11%), superficial thrombophlebitis – in 20 (4.4%) and soft tissue granuloma at the access site was diagnosed in 6 (1.3%) patients.Conclusion. CАC is a highly effective and safe treatment method with 99.4% occlusion rate in s. two-year follow-up period.
Over the last decade non-thermal non-tumescent (NTNT) methods of truncal reflux elimination in chronic venous disease (CVD) are becoming increasingly popular. The main NTNT modalities are mechanochemical ablation and cyanoacrylate adhesive closure (CAC). The advantages of non-thermal ablation are avoidance of tumescent anesthesia, low periprocedural pain and bruising, high patient comfort and satisfaction rates. CAC method has an additional benefit of avoiding the postprocedural compression. CAC is one of promising non-thermal ablation procedures, that leads to truncal vein occlusion and reflux elimination via endovenous delivery of n-butyl-2-cyanoacrylate. This review is aimed at assessment of the updated European and American clinical practice guidelines on CVD management, particularly the role of CAC. Current evidence shows high efficacy and safety of the CAC, its advantages regarding the periprocedural pain and ecchymoses, risk of adverse events, closure rates in the long-term, procedure and recovery time and patients’ quality of life. Therefore, along the current gold standard of varicose vein treatment – thermal ablation, the updated 2022 European and American clinical practice guidelines have significantly emphasized the role of NTNT modalities in general and CAC in particular. Specifically, the European Society for Vascular Surgeons guidelines recommend CAC for patients with great saphenous vein (GSV) incompetence when the NTNT technique is preferred. American guidelines recommend both thermal and non-thermal ablation for the patients with symptomatic axial reflux of the GSV, depending on the available expertise of the treating physician and the preference of the patient.
