The Venous System Anatomy

The venous system is made up of a network of veins, including:

  • Superficial veins
  • Deep veins

Perforator veins connect the deep and superficial venous systems.

The Closure procedure treats venous reflux disease in the superficial venous system, often the underlying cause of painful varicose veins.

Understanding Venous Reflux Disease

Healthy leg veins contain valves that open and close to assist the return of blood back to the heart. Venous reflux disease develops when the valves that keep blood flowing out of the legs and back to the heart become damaged or diseased. As a result, vein valves will not close properly leading to symptoms of:

  • Varicose veins
  • Pain
  • Swollen limbs
 
  • Leg heaviness and fatigue
  • Skin changes and skin ulcers

Superficial venous reflux disease is progressive--symptoms will worsen over time if left untreated.




Are You a Candidate?

Many factors contribute to the presence of venous reflux disease, including:

  • Age
  • Gender
  • Family History
 
  • Multiple pregnancies
  • Obesity
  • Standing profession
Using ultrasound to scan your legs, we can determine if superficial venous reflux is present.
Experience the Closure Procedure

The Closure procedure is performed on an outpatient basis. Using ultrasound, your physician will position the Closure Catheter into the diseased vein, through a small opening in the skin. The tiny catheter delivers radiofrequency (RF) energy to the vein wall. As the RF energy is delivered and the catheter is withdrawn, the vein wall is heated causing the collagen in the wall to shrink and the vein to close. Once the diseased vein is closed, blood is re-routed to other healthy veins.

"The procedure was quick and nearly pain free. I was active following the Closure procedure and noticed immediate relief of symptoms. For me, the Closure procedure was a success!" - Mary C.


Following the procedure, a simple bandage is placed over the insertion site, and additional compression may be provided to aid healing. Your doctor may encourage you to walk, and to refrain from extended standing and strenuos activities for a period of time.

Patients who undergo the Closure procedure typically resume normal activities within a day.

A Treatment That Works

In a comparative trial versus vein stripping surgery, results were in favor of the Closure Procedure. Findings indicated that patients who underwent the Closure procedure:

  • Experienced less post-operative pain and bruising
  • Resumed normal activities within one day
  • Returned to work more than a week earlier than vein stripping patients

At two years following treatment, patients who had undergone the Closure procedure reported superior quality of life compared to vein stripping patients.

The Closure procedure has proven to be highly effective, with higher that 90% of veins treated remaining reflux-free at two years. Results also demonstrate long-term relief of symptoms:

Visual Results

The Closure procedure results in good cosmetic outcome with minimal to no scarring, bruising or swelling.
"The cosmetic appearance of my legs has improved significantly. The bulging veins are no longer present. Now, I look forward to wearing skirts and showing off my legs during the summer months." - Sandra C.
Frequently Asked Questions

Q: Is the Closure procedure painful?
A: Patients report feeling little, if any pain during and after the procedure.

Q: How quickly can I resume normal activity?
A: Patients are walking immediately following the procedure, and patients typically resume normal activites within one day.

Q: How soon will my symptoms improve?
A: Many patients notice an immediate relief of symptoms such as pain, leg heaviness and fatigue. The full benefits of the procedure may take 1-2 weeks.

Q: Is there any scarring, bruising, or swelling after the procedure?
A: Patients report minimal to no scarring, bruising, or swelling following the procedure.

Q: How is the Closure procedure different from vein stripping?
A: During vein stripping, incisions are made in the groin and calf, and a stripper tool is threaded through the diseased vein to pull the vein out of the leg. With the Closure procedure, only one small puncture is made at the insertion site and the vein is the closed and left in place. This minimally invasive approach eliminates pain, swelling, and bruising associated with vein stripping surgery.

Q: What if I need the vein for bypass surgery in the future?
A: The Closure procedure treats diseased veins only, which are not appropriate for bypass surgery. Physicians can use other healthy vessels should bypass surgery be necessary.

Q:Is the VNUS Closure procedure covered by insurance?
A: Most major health insurers cover the Closure procedure. Your physician can discuss your coverage further at the time of the consultation.
