Sclerotherapy is used to address surface level spider veins and small varicose veins. This procedure is a popular method to treat these issues because it is effective, safe, and requires only a very small needle to complete. During a sclerotherapy treatment, our Houston spider vein expert will use a very slender needle to inject a pharmaceutical agent into a problematic vein. This agent irritates the vein walls, causing them to seal shut. Over time, the spider veins fade from sight, leaving you with clearer, better looking legs. 


What to Expect

Because sclerotherapy is minimally invasive, there is no need for general anesthesia. Instead, you’ll be awake and comfortable from beginning to end. During the procedure, you’ll lie back with your legs slightly elevated. After the area is cleaned, Dr. Rao will use a very slender needle to inject the solution into the problematic vein. Most patients feel very little to no discomfort at all throughout this procedure. Sclerotherapy allows Houston spider vein doctors to treat more than one vein at the same time. However, there is a limit to how many veins can be addressed in a session. When you consult with Dr. Rao before your treatment, he will advise you on how many treatment sessions will be necessary to completely eliminate your spider veins. 


After the Procedure

You’ll have a chance to rest for a few minutes after your procedure. Most patients are able to return to their daily activities immediately afterwards, but we do caution everyone to avoid strenuous activities for two weeks. We also encourage sclerotherapy patients to wear compression stockings for two weeks after their procedure to ensure optimal outcomes. Most of our patients see visible improvement in their spider and small varicose veins in three to six weeks. It is recommended that patients continue moving and walking as much as possible to allow for proper blood flow. There should be no scarring after the procedure, but it is not unusual to feel hard tender knots on the skin surface (with some redness) since it is a sign of the vein closing.
