Dr. Anthony Alfieri of the Delaware Advanced Vein Center in Newark, DE earned a medical degree from the Philadelphia College of Osteopathic Medicine in 1985. Soon after, he completed his residency and fellowship to specialize in cardiovascular conditions. Today, he’s a cardiologist who provides the VNUS vein procedure with precision and confidence.
What’s a VNUS Vein Procedure?
VNUS, once known as the Venefit procedure, is a minimally invasive procedure used to treat varicose veins.
How Does it Work?
VNUS works by using radiofrequency energy. This energy heats and then collapses the vein. Next, it seals off the blood vessels. The first part of the procedure consists of the physician using an ultrasound map to determine which veins require treatment. The physician will then use a catheter, which is just a thin tube. A small incision is made, and then the catheter is inserted into the vein. The physician sends heat through the catheter in 20-second intervals. The heat stimulates the collagen that’s in the walls of the vein. The contractions cause the vein to shrink and eventually stop working, which is known as ablation. The catheter is then removed out of the incision.
What Happens to Blood Flow When the Vein Shuts Down?
The blood flow will reroute to healthier veins once the varicose vein closes. It doesn’t disrupt the person’s cardiovascular system at all.
What Are the Benefits of VNUS?
It’s a minimally invasive procedure because it only requires a small incision. The procedure doesn’t require a hospital stay or any healing time.
What’s the Recovery from VNUS Like?
The patient will be able to walk after the procedure; however, it may take a day or two to regain the ability to resume life as usual.
What Are the Side Effects?
Side effects are very minimal. It’s possible for the procedure to scar, but it’s usually minimal. It’s a small incision, so there isn’t much risk of infection. Skin burns are possible. The patient may experience small or large blood clots. Pain or a prickling feeling due to nerve damage may occur, but with a skilled physician from Delaware Advanced Vein Center, the possibility is decreased.
