Endovenous Laser Treatment (EVLT)
Endovenous laser treatment (EVLT) is the most effective treatment for varicose veins. Palm Clinic has treated more than 3000 cases of varicose veins with laser making it the most experienced Vein Clinic in New Zealand with this popular non surgical vein treatment. The laser vein treatment is sometimes referred to as endovenous laser ablation (EVLA).
Endovenous laser treatment has the lowest recurrence rate for varicose veins compared with vein surgery or Ultrasound Guided Sclerotherapy (UGS).
Endovenous laser treatment uses a laser fibre which is inserted into the vein and passed up to the groin where the abnormal valve is. The varicose vein is surrounded by local anaesthetic. The laser is turned on and slowly withdrawn to permanently seal the Varicose Vein.
At Palm Clinic we use the Cooltouch CTEV laser for varicose veins. This is an ND:Yag 1320nm laser which targets water in the vein wall. Local anaesthetic is placed around the varicose vein which collapses the vein and the laser heats the vein wall forming a permanent seal. Initial studies have shown At Palm Clinic we have achieved 100% closure of varicose veins using laser and 5 year studies indicate greater efficacy with endovenous laser treatment than with surgery or UGS.
After the main trunk of the varicose vein has been treated with the laser you will have some UGS injections to smaller branch veins. You are then required to walk for 20-30 minutes before returning to work or home. A follow up appointment a day or two later may involve some further Ultrasound Guided Sclerotherapy to tidy up residual branch veins.
Endovenous laser ablation is especially useful for large varicose veins but there is a requirement that the vein is straight in the thigh or upper calf component – this can only be ascertained with a Duplex ultrasound examination which is performed before treatment. For those patients who are unsuitable for endovenous laser treatment we use Ultrasound Guided Sclerotherapy - this proven technique was pioneered in New Zealand by Dr John Barrett at Palm Clinic.
Dr John Barrett is Chairman and a Foundation Fellow of the Australasian College of Phlebology and with four other phlebologists runs the busiest Vein Clinic in New Zealand. We have performed well over 3000 EVLT cases since 2004 and over ten thousand legs have been treated non surgically with either EVL or UGS.
Varicose vein treatment with Endovenous Laser Ablation is covered by medical insurance when medical necessity criteria apply. Palm Clinic is an affiliated provider to Southern Cross Healthcare and is the only preferred provider for NIB (formerly Tower). This means we can do your prior approval online. EVLA is also covered by most other insurers such as Unimed and Sovereign.
