Endovenous Laser Treatment (EVLT)
Definition - What does Endovenous Laser Treatment (EVLT) mean?
An endovenous laser treatment (EVLT) removes varicose veins by using an optic fiber that transfers laser light into the vein. This process causes the vein to contract, which limits the blood supply resulting in fewer varicose veins. Varicose veins are considered unsightly, but can also be uncomfortable and pose serious health risks in the long term.
TheConsultation explains Endovenous Laser Treatment (EVLT)
Varicose veins are caused by valves in the vein that are not functioning as they should. Blood flows back instead of being pushed upward and this gives the veins a prominent appearance. In the past, doctors had to resort to surgery that involved the removal of entire veins to solve the problem, but non-surgical methods, including endovenous laser treatment, are less invasive.
An endovenous laser treatment is completed through a tiny puncture in the skin. A very fine tube (catheter) houses the optic fiber. It is inserted into the vein and guided via an ultrasound until it reaches the desired site. Then, the doctor triggers the laser. The vein contracts while the catheter gently withdraws, allowing it to close off.
With varicose veins, reopening of the veins and a recurrence of varicose veins are a concern. However, in a trial, a 61-month post-procedure study found that veins remained properly closed in 98.1% of cases. The study also found a lower incidence of side-effects than expected for the more established vein removal or vein stripping procedure.
Although the process is minimally invasive, patients will wear a compression garment for about three weeks after the treatment.
