Mini Vein Surgery

Mini Vein Surgery (Endovenous Laser Therapy)

Endovenous laser therapy (EVLT) is a modern, minimally invasive solution for treating varicose veins—those enlarged, twisted veins commonly seen on the legs. Using targeted laser energy, this procedure seals off damaged veins from within, allowing the body to naturally reroute blood flow through healthier vessels.

Over time, the treated vein is absorbed by the body, leading to improved circulation and a smoother skin appearance.


How the Procedure Works

A thin laser fiber is inserted into the affected vein through a small entry point. Controlled heat generated by the laser causes the vein walls to collapse and close. Once sealed, the vein gradually fades, while nearby healthy veins take over normal blood flow.

When Is This Treatment Recommended?

You may benefit from laser vein therapy if you experience:

  • Aching, heaviness, or fatigue in the legs
  • Swelling around the lower limbs
  • Skin irritation or inflammation near visible veins
  • Prominent, bulging veins that affect your confidence

Although varicose veins are often not dangerous, they can cause ongoing discomfort and cosmetic concerns if left untreated.
