Closure procedure is a minimally invasive treatment alternative for patients with a condition known as superficial venous reflux, which can cause pain, swelling and varicose veins in your legs. Approximately 25 million people in the United States suffer from this condition. Closure procedure provides a less-invasive alternative to painful vein stripping surgery by closing the diseased vein instead. Closure procedure is a minimally invasive procedure that treats varicose veins. It is an outpatient treatment which can be performed under local anesthesia. Experienced physicians often complete the procedure in 45 to 60 minutes. Conversely, stripping is often performed under general anesthesia which necessitates a longer time within the medical facility.
The Closure catheter is positioned into the diseased vein, through a small opening in the skin. The tiny catheter delivers radiofrequency (RF) energy to the vein wall. As we see, these minimally invasive surgical procedure uses radiofrequency energy to occlude, or close, the saphenous vein. As the RF energy is delivered and the catheter is withdrawn, the vein wall is heated, causing the collagen in the wall to shrink and the vein to close. After treatment, ultrasound imaging is used to confirm closing of the vein. If a portion of the vein is not closed, the catheter can be reinserted and energy reapplied. When the closure procedure is finished, a bandage is placed over the insertion site and your leg may be wrapped for a day to aid healing.
Patients can walk away from the procedure and be back to everyday activities typically within a day.
What are the main advantages of closure procedure?
- Faster return to work and normal activity
- Less post-operative recuperation time
- Less post-operative pain and limitation of physical activity
- Higher quality of life scores than vein stripping
