As you may already know, Venaseal is a treatment that involves the application of a Medical Grade ‘Superglue’ into the disease vein, that collapses and permanently seals the vein off. It is a quick, minimally invasive procedure that takes approximately 15 minutes in experienced hands.

What is Venaseal made of?

Venaseal adhesive is a special type of medical super-glue referred to as a “Cyanoacrylate”. It is very carefully formulated in specially designed labs and has some unique properties when compared to other medical grade glues on the market.

  1. When it comes into contact with blood within the vein wall, it polymerises rapidly. What this means is that it rapidly seals the vein shut upon application, with minimal migration.
  2. It is very soft and elastic, so that it is undetectable by the patient after application.
  3. Has an “anti-microbial” effect against gram positive organisms.
  4. No adverse long term effects.


Cyanoacrylates have been in use since the 1950s. They have been used in repairing wounds and skin incisions. As an emergency doctor, one of our go-to treatments for children with lacerations was ‘Histoacryl Blue skin adhesive’. It was quick and avoided the need for suturing, particularly when faced with a distressed and alarmed child.

It has also been used in the following areas of medicine:

  • Ophthalmic surgery
  • Cosmetic Procedures
  • Dental
  • Orthopaedic
  • Intravascular Occlusion of Cerebral Arterio-Venous Malformations (AVMs), Varicoceles and Pelvic Congestion Syndrome and Gastric Varices.
