Sclerotherapy
Medical Treatment for Spider Veins and Small Varicose Veins
Sclerotherapy is a medically accepted procedure used to treat spider veins and small varicose veins of the legs. At our clinic, sclerotherapy is performed by qualified healthcare professionals and is limited to veins appropriate for in-office treatment.
The purpose of sclerotherapy is to reduce the appearance of visible veins and, in some cases, to relieve mild symptoms such as aching or heaviness. It does not prevent new veins from forming.
What to Expect During Treatment
Sclerotherapy involves injecting a medical solution (sclerosant) into targeted veins. The solution causes the vein walls to close, after which the vein is gradually absorbed by the body. Blood flow is redirected through surrounding healthy veins.
The procedure is performed in-clinic, requires no incisions, and typically lasts 30 to 60 minutes depending on the number and size of veins treated.
Pre-Treatment Checklist
Preparation - Legs are cleansed with an antiseptic solution. Your provider will review your medical history, medications, and any previous vein treatments.
Injection Process - A very fine needle is used to inject the sclerosant directly into each targeted vein. Patients may briefly feel mild stinging, burning, or cramping during injection. Multiple veins can be treated during a single session.
Post-Injection Care in Clinic - Bandages are applied immediately after treatment, and you will be asked to put on your compression stockings. Your provider will review post-treatment instructions and answer any questions.
Duration and Comfort - The procedure typically takes 60 minutes. Patients can walk immediately after treatment and can resume normal activities the same day.
Post-treatment Checklist
Wear compression stockings as instructed (usually several days to weeks).
Walk regularly to promote circulation.
Avoid strenuous exercise, heavy lifting, or high-impact activity for several days.
Avoid hot baths, hot tubs, and saunas for at least 48 hours.
Avoid sun exposure to treated areas until any bruising resolves.
Expect mild bruising, redness, or firmness along treated veins, which typically resolve without intervention.
Recovery and Expected Results
Spider veins usually fade within three to six weeks.
Small varicose veins can take several months to resolve.
Some patients require multiple sessions for optimal results.
Sclerotherapy treats existing veins but does not prevent new veins from developing.
who might not be suitable
Sclerotherapy may not be appropriate for individuals who:
are pregnant
have active skin infections in the treatment area
have a history of certain clotting disorders.
A medical referral is required for treatment.
Potential Risks and Complications
Sclerotherapy is generally considered safe. Potential temporary side effects include:
bruising
redness or swelling
mild tenderness
temporary darkening of treated veins
Rare complications can include blood clots, allergic reactions, or skin ulceration. Your provider will review risks relevant to your health during the consultation.
To help ensure safe and effective treatment:
Avoid tanning or sun exposure on the legs for at least two weeks before treatment.
Do not apply lotions, oils, or self-tanning products on the day of treatment.
Wear loose, comfortable clothes.
Bring prescribed compression stockings if advised.
Inform your provider of all medications, supplements, and medical conditions.
Postpone treatment if you are pregnant.
