VenaBlock Vein Glueing

What is VenaBlock made of?

As you may already know, VenaBlock 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 and completely painless procedure that takes approximately 15 minutes in experienced hands.

VenaBlock 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.

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.

It is very soft and elastic, so that it is undetectable by the patient after application.

Cyanoacrylates have been in use since the 1950s. They have been used in repairing wounds and skin incisions.

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.

What are the advantages and disadvantages for VenaBlock?


  • Minimal discomfort as there is no need for injection of Tumescent Anaesthetic along the course of the vein.
  • No need for compression stockings.
  • Minimal time off work.
  • Return to Normal Activities.
  • No chance of Nerve Damage or Thermal Injuries.

Treated Veins may become quite inflamed and require Anti-lnflammatories and time to settle. This is however, no different to Endovenous Laser Treatment of Veins.

What to expect from the VenaBlock Procedure:

  • A duplex ultrasound is used to map out your vein.
  • Local anaesthetic is then applied to a small area in the lower leg.
  • A thin catheter is inserted through a tiny entry point, usually near the knee.
  • VenaBlock Glue is then injected through the catheter using a special applicator and into the vein.
  • The Glue is applied evenly along the length of the vein.
  • A stocking is not required following this procedure. Patients will be instructed to get dressed and will be given all the necessary Post Operative Instructions.
  • Walking immediately after the procedure is encouraged. Normal daily activity can be resumed right away – just avoid rigorous activities such as gym workouts.
  • There may be minor soreness in the thigh. Usually this can appear a few days to a few weeks later, and should not be a concern. Any discomfort can be treated with over-the-counter, non-steroidal anti­inflammatories only after consultation and discussion with your doctor.

How Effective is the VenaBlock Procedure?

The published success of the VenaBlock Closure Procedure is up to 95.8%, with far fewer complications than EVLA or surgery.

VenaBlock has been trailed in Europe over the last 3 years. Results published show a low risk of complications and excellent medium-term results. The study showed a 99.4% closure rate at 12 months. VenaBlock is considered as effective as Endovenous Laser Ablation but does not involve the use of heat and can therefore be performed with the application of a small amount of local anesthetic as opposed to a Nerve Block or large volumes of Tumescent Anesthetic.

It is possible to treat two or more veins in the one session. Stockings are usually not necessary and patients are able to return to normal activities immediately.
