VenaBlock® Cyanoacrylate Closure · Vein Sealing System
Non-Thermal Endovenous Closure
Cyanoacrylate adhesive closure carries a Class IIa, Level A recommendation in the ESVS 2022 guidelines when a non-thermal, non-tumescent technique is preferred.
Why Non-Thermal Closure
Continuous Delivery Technique
Controlled, continuous cyanoacrylate delivery during catheter pull-back under duplex ultrasound guidance, with immediate external compression over the treated segment.
No Thermal Energy
No heat is generated at any point, structurally avoiding the thermal nerve injury and skin burns associated with laser and radiofrequency ablation.
No Tumescent Anaesthesia
Local anaesthetic at the access site only. In published VenaBlock® study protocols, patients mobilised the same day and compression stockings were not mandated.
