Superficial venous reflux occurs when vein valves in the legs become damaged or diseased, causing blood to pool in the legs. Varicose veins are an underlying symptom of venous reflux. Other symptoms include pain, swelling, leg heaviness and fatigue.
The Vein Clinic of North Carolina offers the VNUS Closure procedure, a minimally invasive treatment for superficial venous reflux. The valves can’t be repaired, so the blood flow is re-routed through healthy veins. During the Closure procedure, a thin catheter is inserted into the vein and delivers radiofrequency energy to the damaged vein wall. The energy causes the wall to heat, collapse and seal shut. Once the diseased vein is closed, blood empties from your legs through other healthy veins.
The Closure procedure takes approximately 45 minutes to an hour to complete, although patients will be at the medical facility two to three hours because of pre- and post-treatment procedures. A local anesthetic numbs the treatment area during procedure, so patients report feeling little if any pain. Many patients resume normal activities almost immediately and notice improvements to their symptoms within one to two weeks.
If venous reflux has caused you symptoms, schedule an appointment with one of our providers to discuss treatment options. You may be a candidate for the Closure procedure that will have feeling symptom-free in no time.
