VenaBlock® Cyanoacrylate Closure · Vein Sealing System

Non-Thermal Endovenous Closure

IIa · AESVS 2022 guideline class

Cyanoacrylate adhesive closure carries a Class IIa, Level A recommendation in the ESVS 2022 guidelines when a non-thermal, non-tumescent technique is preferred.

VENABLOCK®

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.
