VenaSeal: The Safe and Effective Alternative to Thermal Ablation

Varicose veins cause a significant amount of distress. You may be too familiar with the burning, throbbing and itching associated with problematic veins. Years ago, the only option for permanent varicose vein treatment was surgical, vein stripping. Advances in technology made way for non-surgical treatment alternatives.

Within the past twenty years, vein specialists have typically suggested thermal ablation, in the form of lasers or radiofrequency, as a less-invasive alternative to surgery. With thermal ablation, heat is focused inside the vein to close and permanently eliminate it. Today you have another option; you can have your troublesome varicose veins glued with VenaSeal vein closure.

The Cause of Your Varicose Veins

Your veins have a one-way valve to direct your blood flow to your heart. When a valve doesn’t close sufficiently, it allows blood to leak backward into the vein. This is known as venous insufficiency. Your bulging, uncomfortable veins are the result of leaky valves. Varicose veins do not heal on their own and get worse over time. As your veins enlarge and twist, you may begin to experience complications, such as pain, skin ulcers, and blood clots.

Treating Varicose Veins with Thermal Ablation

Thermal ablation is much less invasive, and more comfortable than surgery. During thermal ablation, diseased veins are typically injected with a tumescent agent, a compound that numbs the treatment area and conducts heat, through a small catheter. The number of injections is dependant upon the length of the vein. Thermal ablation typically requires multiple tumescent injections.

After the area is numb, short burst of heat is used to injure and collapse the vein.  The vein is eventually replaced with connective tissue as it heals from the heat exposure. Recovery from thermal ablation can take several days. Compression garments are typically worn after the procedure to facilitate healing.

Treating Varicose Veins With VenaSeal

The  VenaSeal closure system is a safe and effective alternative to surgery or thermal ablation. This non-thermal alternative uses a safe, non-toxic, pliable medical adhesive to seal varicose veins.  A small, predetermined amount of medical adhesive is injected into the vein, through a small catheter, at a single entry point. You won’t need to endure multiple injections. Some of the additional VenaSeal advantages include:

  • Less discomfort and bruising
  • No need for a tumescent agent
  • No risk of nerve damage or skin burns
  • No need for post-treatment pain medication
  • Return to your normal activities, including work
  • No exercise restrictions
  • No need to struggle with compression stockings while veins heal

Your VenaSeal Vein Closure Treatment

Your VenaSeal vein closure treatment should take 30 to 60 minutes, depending on the length of the vein.  During your treatment, your vein specialist will use ultrasound technology to determine the best location for vein closure. The site will be numbed with a single injection per vein. A small, painless catheter will deliver a specified amount of adhesive to the affected vein.

Temporary pressure is applied to the treatment area to help the vein seal. VenaSeal adhesive sets quickly, that’s why it is often referred to as the “superglue” vein treatment. Your treated vein will be safely absorbed by your body over the next few months. Vein treatment will not harm your circulation. When diseased veins are eliminated,  blood flow is redirected to healthy veins.

There is no need to endure problematic varicose veins. While VenaSeal may not be right for everyone, it could be your best varicose vein treatment plan.

Varicose veins are leg veins which do not pump blood effectively back to the heart and can be often seen as bulging veins just underneath your skin on either leg. These varicose veins have valves in them which are not working effectively so that blood which is meant to be pushed towards the heart, leaks downwards toward the legs. There are other leg veins which are still working, so blood does eventually arrive through other routes to your heart. However, varicose veins do exert added pressure on your circulatory system.

Endovenous Laser Ablation is a Varicose Veins Laser Treatment performed in our clinic under local anaesthetic. This new procedure is an excellent treatment option for most patients with varicose veins and is considered slightly more effective than surgery but without the need for hospitalization. Read More.

This is an endovenous treatment (meaning treating the vein on the inside). It is generally accepted to be associated with less pain and bruising than endovenous laser ablation. It is a “gold standard” form of treatment for large varicose leg veins treatment as the procedure requires no hospitalization or time of work yet is at least as effective as surgery. Read More.

Venaseal™ or ‘superglue’ treatment by Sapheon is the latest surgery free procedure that uses a medical adhesive to safely and effectively treat varicose veins. Unlike other treatments, Venaseal™ does not require tumescent local anaesthetic around the vein, so there is usually only one local anaesthetic injection. The Venaseal™ non surgical treatment procedure also eliminates the use of heat (or thermal energy) so there is virtually no risk of nerve or skin injury or any major reaction to the anaesthetic.

Ultrasound Guided Foam Sclerotherapy allows our doctors to visually guide and monitor a needle to the exact source of the incompetent vein (valve) to be injected. By using ultrasound we can treat more quickly and safely larger and deeper veins that once required more invasive surgical treatment. Foam sclerotherapy is the new form of delivering the sclerosing agent that allows us to treat larger varicose veins that might be unsuccessfully treated with conventional sclerotherapy. The foam solution has the consistency of ‘shaving cream’, which improves treatment in two distinct ways. Read More.
