What are minimally invasive vein interventions?

Minimally invasive vein interventions are a broad term for several non-surgical vascular procedures which primarily focus on the treatment of varicose veins. Varicose veins are veins beneath the skin that have become swollen or twisted. Most commonly, these enlarged veins are found in the legs, but they can also occur in other areas. Minimally invasive techniques have been developed to address varicose veins with less risk and downtime than traditional surgical methods. The goal is to restore proper venous function, alleviate symptoms, and prevent complications.

Benefits of minimally invasive vein interventions

Minimally invasive vein interventions in Wausau at Surgical Associates come with several benefits, including the following:

  • Reduced pain and discomfort
  • Ulcer healing
  • Reduced symptoms of leg fatigue, edema, itching, and skin changes
  • Minimal scarring
  • Shorter recovery times
  • Lower risk of complications
  • It can be performed on an outpatient basis

Common minimally invasive vein interventions

Radiofrequency Ablation (RFA)

Radiofrequency ablation (RFA) is a procedure for the treatment of varicose veins. This treatment involves the insertion of a small catheter through a tiny incision and into the affected vein. This catheter delivers consistent radiofrequency heat to the vein, which contracts the collagen in its walls. As a result, the vein walls collapse and close, which causes blood flow to be redirected to other, healthy veins. 


Sclerotherapy is another minimally invasive treatment option for smaller varicose veins and spider vein treatment in Wausau. This procedure involves the injection of a specially formulated solution, known as a sclerosant, directly into the affected veins. The sclerosant irritates and damages the inner lining of the vein, causing the vein to collapse and eventually fade away over time. Blood flow is then naturally redirected to healthier veins. Sclerotherapy, usually done in an outpatient setting, not only helps alleviate symptoms but also improves the cosmetic appearance of the treated area.


Varithena is an FDA-approved microfoam treatment for varicose veins that works by replacing the blood in the affected vein with a special microfoam. This forces the diseased vein to collapse, forcing the blood to flow into other, healthier veins.


Phlebectomy is a minimally invasive procedure that uses a tiny needle or scalpel to eliminate varicose veins. This treatment is primarily used to target varicose veins located just under the surface of the skin.
