Sclerotherapy is a procedure used to treat both varicose veins and spider veins.

The doctor will inject small amounts of a hardening solution into the vein using a very fine, thin needle. The solution irritates the vein lining, which causes it to collapse and seal shut. As the injected area heals, the treated veins will fade from sight.

Before Your Procedure

  • Your provider may ask you to stop taking medications that increase your risk of bleeding.
  • You may want to shower before your appointment because you cannot shower for 24 hours after the procedure.

During Your Procedure

  • The treatment area will be cleaned.
  • The hardening solution will be injected into the vein using a thin needle.
  • The number of injections will depend on the size and location of the veins.

After Your Procedure

  • You will have compression stockings on when you leave the hospital.
  • Wear the compression stockings day and night for 3 days after the procedure. Removing only to shower.
  • After 3 days, you will wear the stockings for another 14 days. Removing only to shower and at bedtime.
  • You may shower 24 hours after the procedure.
  • No baths for 3 days. Avoid pools, lakes and hot tubs for 1 week.
  • Maintain a normal level of activity.
  • Walk at least 30 minutes today. Continue to do this daily for the next 14 days to promote healing.
  • Do not sit or stand for long periods of time for the first week.
  • Elevate your legs at least 3 times a day for 5 to 10 minutes for the first week.
  • Avoid activities such as weight training or running for 10 days.
  • You may have some discomfort and bruising following the procedure.
  • If not contra-indicated, you may take medication such as Aleve or Ibuprofen to help with any discomfort.
  • If your pain gets worse, you may have trapped blood in the vein. This is a common side effect of the procedure.
  • You may apply warm packs for 30 minutes, 3 times a day. This will help with pain and healing.
  • You may return to work the following day after the procedure.

When to Call Your Doctor

  • Pain not relieved by rest and/or pain medications.
  • Fever greater than 101 degrees Fahrenheit.
  • For problems or concerns call St. Cloud Hospital at 320-251-2700 and ask to speak to the On-Call Interventional Radiologist.

Dear Friends and Neighbors,

CentraCare care givers have been working around the clock for more than 20 months to care for you, your families and friends during COVID. We are committed to caring for every Minnesotan who needs us, and nothing will prevent us from doing so – even during these never-seen-before times.

The challenge of providing this level of care is that our hospital beds are often full. ERs in all of our hospitals are packed. And our clinical teams are exhausted. Early in the pandemic, our community stepped up in amazing ways to help us. We ask that you again join us in fighting this pandemic together.

How can you help?

  • Please get your COVID vaccines and booster shots. They are proven safe and effective in reducing COVID illness, keeping people out of the hospital, and preventing death.
  • If your situation is not an emergency, please use other care options, including:
  • If this is a medical emergency, call 9-1-1, or visit the ER.

Together, we can do this. Thank you for your support.

Ken Holmen, MD
