Ablation is a minimally invasive procedure that safely and effectively closes varicose and spider veins, improving their appearance and reducing uncomfortable symptoms. During the procedure, a vein specialist uses a thin, flexible tube called a catheter, or needle injections, to deliver heat or chemicals to damage the tissue and close the vein.
UPMC doctors and staff treat spider and varicose veins with the most effective and minimally invasive ablation procedures.
There are three types of ablation procedures:
Endovenous thermal ablation is a minimally invasive procedure in which a small catheter is inserted into the affected vein. Controlled heat is then used to collapse the vein as the catheter is removed. This procedure is done in your doctor’s office.
Mechanical ablation techniques are the least invasive vein closure methods available. They involve inserting a small catheter that delivers a safe and effective drug or glue into the diseased vein as the catheter is removed. These methods do not require multiple needle sticks, and patients can return to normal activity immediately after treatment.
Sclerotherapy uses a catheter or tiny needle injections of a medication to collapse your vein, which will later be absorbed into the body. The number of treatments varies according to size and type of veins. You may return to normal activity immediately after treatment.
You may need treatment for varicose and spider veins if you are having uncomfortable symptoms, including:
Most healthy patients with varicose veins are eligible for varicose vein ablation. If you are pregnant and want to treat varicose veins, you'll need to consult with your doctor to discuss any risks that may be associated with ablation procedures.
Ablation is a safe and effective procedure to treat varicose and spider veins. However, like all medical procedures, vein ablation comes with some risks, including:
On the day of your procedure, be sure to bring your photo ID and health insurance card(s). Leave valuables such as cash and jewelry at home.
Your procedure may be performed in your doctor’s office or an outpatient surgery center. You should be able to go home the same day as your procedure. However, you will need to arrange for someone to drive you home after you are discharged.
The procedure takes about an hour.
During your procedure:
You will have local anesthesia or a mild sedative during your procedure. You will be awake, but shouldn’t feel any discomfort.
After the procedure, your treated vein(s) will no longer be able to fill with blood, forcing the blood to reroute through healthier veins.
You can resume normal activities immediately after an ablation procedure; however, you should avoid strenuous activities for 1-2 weeks. To prevent blood clots, you will wear compression socks or bandages for several days or weeks following the procedure.
You should call your doctor if you are experiencing any unusual symptoms, including:
If any of these symptoms are severe, you should dial 911 immediately.
