Healthy leg veins contain valves that open and close assisting in the return of blood from the legs to the heart:

The following contribute to the development of venous reflux and varicose veins:

Thanks to modern technology, venous reflux and varicose veins can now be treated with a minimally invasive procedure known as ClosureFast. Not only is this procedure quick and relatively painless, as opposed to surgery, but it has also shown great success rates with nearly a 95% reflux free rate at 5 years follow up.

Venous reflux is a medical condition which progresses over time into a more serious medical condition called Chronic Venous Insufficiency (CVI). The increased pressure inside the veins, secondary to pooling of the blood in the legs, leads to varicose veins.

Spider veins and reticular veins are small, web-like, blood vessels that are easily visible on the surface of your skin. They can be red, blue, or purple and are commonly associated with varicose veins. Spider veins range in diameter from 0.1 to 1 mm. Reticular veins are dilated bluish sub-dermal veins measuring between 1 and 3 mm in diameter. When veins are more than 3mm in diameter, they are referred to as varicose veins. Varicose veins, although still visible through the skin, are usually larger, raised blood vessels that are swollen.
Reticular Veins

Spider Veins
Although spider and reticular veins are considered a cosmetic problem, they are often a result of underlying venous reflux in the larger veins. When reflux develops in the larger veins and results in the veins becoming bigger, the pressure is often transmitted to the nearby smaller veins under the skin and these manifest as spider veins and reticular veins. Therefore it is imperative that while seeing a patient with spider veins, the clinician also rules out underlying reflux in the larger veins which may be the cause of the problem.

Venous reflux and Chronic Venous Insufficiency (CVI) are diagnosed by Dr. Ramaswami in the office using non-invasive ultrasound examination. The test takes around 30 minutes and is the gold-standard for diagnosing the site and severity of venous reflux in the veins of the leg.

Dr. Ramaswami will also take a detailed history and do a thorough physical examination to ensure problems are not caused by something else.
Treatment
The traditional treatment of varicose veins included surgery in the operating room with venous ligation and stripping. This was accompanied by significant patient discomfort, leg bruising, pain and delayed recovery. Surgery has, for the most part, been replaced by minimally invasive venous ablation procedures, which are performed in the office setting. Closure of refluxing superficial veins is achieved using Radio Frequency Ablation. Studies using the ClosureFast™ catheter have shown, less pain, fewer complications, better quality of life and nearly 95% reflux free rate at 5 years follow-up.
The ClosureFast™ catheter is inserted into the vein through a tiny incision below the knee. Guided by ultrasound imaging, the physician treats a 7 cm segment of vein with a 20-second burst of radiofrequency energy, causing the vessel to shrink around the catheter. The physician withdraws the catheter, treating each segment until the entire length of the vein has been sealed. Unlike painful vein stripping surgery, the catheter delivers uniform, consistent heat to each segment and temperatures do not exceed 120° C. As a result, the ClosureFast™ procedure causes less bruising and allows for rapid patient relief and recovery. The ClosureFast™ procedure is performed in our office.
The ClosureFast™ procedure is a minimally invasive treatment for varicose veins and Chronic Venous Insufficiency (CVI) in which a vein specialist inserts a ClosureFast™ endovenous radiofrequency ablation (RFA) catheter to collapse and close enlarged leg veins. After the vein is sealed shut, blood then naturally re-routes to healthy veins.
