If varicose veins are plaguing your life, the doctor may be suggesting a comprehensive treatment option called VNUS Closure. There are a number of procedures that deal with these problem veins, but VNUS is one of the more common vein treatments out there. To understand more about this effective way to improve leg circulation, you need to learn about varicose veins and how the VNUS treatment works.
What are Varicose Veins?
Varicose veins are twisted, enlarged veins that often show near the surface of the skin. They are caused by weakening valves in the walls of the veins. The vein network in the legs must push blood up towards the heart working against the force of gravity. To make this happen, the valves built into the walls of the vein open and close to hold blood in place as it moves upward.
As a person ages, the vein walls lose some of their elasticity. This can cause valves to gap open allowing blood to flow backwards. Blood will then pool up around the next working valve, causing the vein to become engorged. This is a varicose vein.
What is the VNUS Closure Procedure?
VNUS Closure allows vein doctors to reach a diseased vein and force it to close. Once closed, the body reroutes blood flow, making use of healthy veins instead. The varicose vein will disappear completely over time.
With VNUS Closure, vascular surgeons use ultrasound to guide a catheter into the problem vein through a tiny incision in the leg. The catheter delivers a burst of radiofrequency energy to the vein wall. This irritates the wall and the vein collapses.
What are the Side Effects of VNUS Closure?
This is a minimally invasive procedure done on an outpatient basis. There is no hospital stay or down time. After the surgery, the staff puts a bandage over the incision site. The doctor may prescribe compression stockings, as well, to aid in healing and improve blood flow.
You might feel some pulling during the procedure or slight muscle cramping. Afterwards, there may be minor bleeding from the incision site and some discoloration. The risk of complications is very low. The surgeons will discuss possible problems with you prior to starting the procedure.
What is the Recovery Time for VNUS Closure?
You should be up and around almost right away. You can return to non strenuous activities after leaving the office. The doctor may suggest you avoid some types of exercise or work for a few days. Walking is a good way to improve leg circulation while the incision site heals.
Ultimately, it is up to the doctor to decide if you are a candidate for VNUS Closure, but if you have varicose veins, this procedure is a likely option.
