Endovenous Thermal Ablation

Endovenous treatments ('from within the vein’) have emerged as effective alternatives to surgery, for the management of varicose veins and chronic venous disease. Rather than surgically removing the problem veins, these techniques involve sealing the veins closed, rerouting blood to nearby healthy veins.  These treatments are equally suitable for symptomatic venous disease, or for those bothered by the cosmetic appearance of unsightly varicose veins.

The Process

Widely performed since 2001, Endovenous Laser Therapy (EVLT) uses heat energy to seal malfunctioning veins.  Guided by ultrasound imaging, a catheter is threaded through the vein in the lower leg, and advanced to the top of the target vein, commonly in the groin.  Delivery of energy by way of the laser fibre causes direct thermal injury to the vein wall, as the device is withdrawn through the diseased vein.  

This form of treatment requires tumescent anesthesia, a form of local freezing, along the length of the target vein, in order to promote vein collapse and pre-vent injury to surrounding tissue.

Compared to traditional surgical methods, endovenous thermal ablation has numerous advantages:

• Office-based, minimally invasive intervention
• Decreased overall risk
• Less post-procedure pain
• More rapid return to regular daily activities

Clinical evidence suggests equivalent efficacy of endovenous ablation compared to surgical vein stripping, with a reduction in the rate of long-term recurrence.

After successful endovenous thermal ablation of the culprit surface veins that are responsible for back flow and blood pooling, sclerotherapy may be necessary to treat residual varicose veins.  For details, visit the dedicated Sclerotherapy information section.

Currently, endovenous treatments are not covered under OHIP. Contact Own Health for details regarding pricing.

How It Works

(As seen in the Image on left)
(As seen in the Image above)
Step 1
Local freezing at vein access site
Step 2
Endovenous devices threaded through vein
Step 3
Ultrasound used to guide laser fibre to top of target vein
Step 4
Tumescent anesthesia (a form of freezing) along length of vein to be treated
Step 5
Heat energy delivered inside vein as catheter slowly withdrawn
