VenaSeal Closure

What Is VenaSeal?

Vein disease occurs when bad veins in our legs no longer do their job and allow blood to pool in our legs. This can lead to many symptoms and enlarged varicose veins.

VenaSeal is an in-office procedure that utilizes a medical adhesive to close bad veins in the legs to alleviate symptoms such as swelling, achiness, fatigue, heaviness of the legs.

Our doctors have extensive experience performing this procedure, making us some of the most knowledgeable vein specialists in Houston.

When Is VenaSeal Needed?

Generally used to help alleviate symptoms such as:

  • Aching
  • Swelling
  • Skin irritation
  • Discoloration
  • Inflammation
  • Restless legs
  • Cramps
  • Open sores or ulcers


The leg being treated will be cleaned, sterilized, and covered with a surgical drape. Your physician will numb the area where the catheter will enter into the abnormal vein and use the ultrasound transducer or wand to study the vein and track its path. A very small skin incision is made at the site.

Using ultrasound guidance, a catheter or vascular access sheath is inserted through the skin and positioned within the abnormal vein. The medical adhesive will be delivered to close the bad vein after which the catheter is removed from the body.

A small bandage is used to cover the small skin opening and the leg is wrapped with a compression wrap. No stitches are needed.


Who Performs The Procedure?

Image-guided, minimally invasive procedures such as endovenous ablation are performed by a specially trained vascular physician.

Does The Procedure Require Anesthesia?

Patients are given a mild sedative by mouth (Valium) to help them to relax. Local numbing medicine is also used.

How Long Does The Procedure Last?

This procedure is usually completed within an hour.


What Are the Possible Risks of the Procedure?

VenaSeal closure is safe, less invasive than conventional surgery, and leaves virtually no scars. It is one of the safest choices for vein treatment in Houston.

However, you may experience some side effects. These include:

  • Tenderness, which can be alleviated by wearing compression stockings
  • Burning, pain, or prickling after recovery
  • Small or large blood clotting in veins
  • Phlebitis – inflammation of the vein
  • A sudden onset of a swollen leg
  • Hypersensitivity reaction to the adhesive alleviated by taking Benadryl
  • Hyperpigmentation – darkening of the skin


Before the Procedure

Taking Medication

You should report all medications you are taking, including herbal supplements, and if you have any allergies, especially to local anesthetic medications and general anesthesia.

Do not discontinue any of your medications without first talking to your healthcare provider. Ask your doctor which medications you should stop taking and when to stop taking them.

What to Bring

  • A family member to wait with you before the procedure
  • Comfortable, easy-to-fold clothing
  • Do not bring any jewelry, watches, and/or valuables


How to Prepare

Do not put lotion on your legs before the procedure.

After the Procedure

What to Expect After the Procedure

Following the procedure, you will need to wear a gradient compression stocking to help reduce bruising, tenderness, and minimize the possibility of blood clots forming for a minimum of 2 days, up to 1-2 weeks or as advised by your physician.

Pain after ablation is typically less than after vein surgery.

Activity Guidelines

You may resume your normal activity immediately, with the exception of air travel or prolonged sitting. Refrain from heavy lifting or other strenuous activities for a few days.

To avoid increasing the chance of complications, remain active and do not spend too much time in bed during the recovery process.

In addition, you should avoid the following for 1 week after treatment:

  • Hot baths
  • Hot compresses
  • Whirlpools or saunas
  • Direct exposure to sunlight
  • Showers are permitted, but the water should be cooler than usual
  • Any vigorous aerobic activity or heavy lifting



A follow-up ultrasound examination is essential in order to assess the treated vein and to check for adverse outcomes. Within one week, the target vein should be successfully closed; however, full response to treatment may take up to 6-8 weeks.
