Venous Insufficiency Q & A

What is venous insufficiency?

Veins carry your blood back to your heart and contain valves that help push your blood against gravity and up toward your heart. Venous insufficiency is a vascular condition that occurs when these valves become damaged. Damaged valves can cause the blood to flow backward (venous reflux) and increase the pressure in your legs.

Over time, the pressure on your leg veins can cause symptoms, including restless legs, visible leg veins, leg and ankle swelling, and neuropathy.

A chronic venous obstruction occurs when there’s a blockage in the veins. A blockage usually happens when scar tissue in the vein causes damage to your valves, backward flow, or poor return of blood flow to your heart.

Chronic venous insufficiency or venous obstruction can lead to a number of vein-related problems, including leg ulcers. With damaged valves, when the blood pools in a vein, fluid can leak out of that vein and into your surrounding tissues. The tissues are broken down by your body, and an ulcer forms.


What causes venous insufficiency?

A number of primary risk factors might be involved in the development of venous insufficiency, such as:

  • Genetics and family history
  • Multiple pregnancies
  • Prolonged standing

In men, venous insufficiency is more likely to be related to genetics and, in women, it’s most commonly linked to hormonal fluctuations and pregnancy. During pregnancy, the uterus can put pressure on your leg veins.


What are the treatments for venous insufficiency?

Dr. Wieters provides effective treatments for venous insufficiency, including the ClosureFast radiofrequency ablation procedure.

Dr. Wieters conducts an examination and offers in-house ultrasounds and further testing as necessary. Many treatments are designed to close off problem veins or seal a segment of a problem vein.


The ClosureFast™ radiofrequency ablation procedure is performed in the office under local anesthesia. With the ClosureFast™ procedure, Dr. Wieters uses ultrasound to position a tiny catheter inside the incompetent superficial vein thereby addressing the source of the problem. Radiofrequency energy is safely delivered through the catheter to seal the vein. Closed diverting the blood to healthy functional vessels.

Ultrasound-guided chemical ablation

Chemical ablation involves the injection of a safe and effective, FDA-approved solution to close those veins which are not amenable to the ClosureFast™ procedure or other modalities.
