Sclerotherapy is a commonly used method to reduce and close varicose, reticular and spider veins. Veins are injected with a sclerosing agent that irritates and closes the vein. Best results of sclerotherapy treatments are visible 4 to 6 months after injections.

What to Expect

Most patients require several treatments of sclerotherapy to obtain optimal results. Treatments are typically scheduled in 4 week intervals. There is no recovery period and bed rest is not required. Exposure to the sun should be avoided for 2 weeks after treatment to prevent skin discoloration.

Travelling by air must be avoided for at least 2 weeks following sclerotherapy due to an increased risk of blood clot formation.

Following a sclerotherapy treatment patients are required to wear compression stockings for 3 consecutive days and nights. Bathing, showering, swimming, heavy lifting and extreme physical exercise or activities should be avoided during this 3 day period.

Risks Associated with Sclerotherapy

• Skin discoloration can take 6 to 12 months to disappear; can also be permanent.
• Failure of treatment; it is successful for 80% of patients.
• Itching, bruising, pain, and blistering where the veins were treated.
• Scarring resulting from ulcers or deterioration of the tissue around the treated vein. This is rare.
• Blood clots or damage in the deep vein system (DVT).
• Allergic reaction to sclerosing agent is possible but uncommon.

Common Effects of Sclerotherapy

Following sclerotherapy it is normal to experience bruising, tenderness and redness at the injection sites. In larger veins, as the healing progresses and the veins begins to close, it is common for small lumps to develop along the length of the vein. This is normal and is an indication that the treatment is working.
These common effects of sclerotherapy will dissipate on their own. An anti-inflammatory drug such as Advil or Aleeve, along with a cold compress or ice packs can be used to alleviate any discomfort if necessary.
