Venous insufficiency occurs when valves in the leg veins no longer function properly, causing blood to pool in the vein. Over time, symptoms can occur.  


Symptoms include:

  • leg pain

  • varicose veins

  • burning or itching of the skin

  • restless legs

  • swollen legs and ankles

  • color and texture changes of the skin

  • open wounds


Chronic venous insufficiency is diagnosed with an ultrasound exam.  The test takes approximately 30 minutes to complete and can be performed in the doctor's office.


Dr. Huang offers minimally invasive and definitive treatment for patients with venous reflux disease.  



The procedure involves placing a small catheter in the diseased vein to close the vein with radiofrequency energy.  Tumescent local anesthesia is administered for patient comfort and to maximize contact of the diseased vein with the catheter.  One vein can be closed within minutes, and the entire procedure can be completed in 30 minutes from beginning to end.   After the defective vein is closed, blood is re-routed to normal veins.


The VenaSeal closure system uses an advanced medical adhesive to close the vein.  No tumescent anesthesia is required, minimizing patient discomfort.  Diseased veins in both legs can be treated in one session, maximizing results in a short period of time.  Post-procedure, no bandaging or compression stockings are required, and patients can return to normal daily activites with minimal recovery time.
