What is EVA?
EVA is a relatively new and minimally invasive method for treating varicose veins without the need for surgery.
How long does it take?
The EVA procedure takes approximately 45 minutes.
Risks and Complications:
There is a slight risk of deep vein thrombosis (DVT); approximately 1 in 300 in the 2 to 4 weeks post treatment. The risk of DVT is reduced by prescribed exercise (walking) immediately after the procedure and during a follow-up ultrasound examination. There is also a slight risk of patchy numbness; approximately 1 in 150. This is the result of irritation or damage to superficial nerves adjacent to the treated veins. Most cases of numbness resolves spontaneously over 3-6 months.
What is involved?
- The radiologist will map out the vein with the faulty valve identified on the initial visit.
- Local anesthesia is applied.
- A thin catheter is inserted through a tiny entry point, usually near the knee and guided by ultrasound to the area of concern.
- Thermal energy is delivered to seal the faulty vein.
- Walking immediately after the procedure is prescribed.
- Normal daily activity can be resumed (just avoid rigorous activities, such as gym workouts.
- There may be minor soreness and bruising. Any discomfort can be treated with over-the-counter, non-aspirin pain relievers as needed.
- Published clinical studies show that EVA has a 98% initial success rate with excellent long term results.
