Clarivein: What It Is and What to Expect

What kind of doctor provides Clarivein?
Clarivein is usually done by a vascular surgeon or another doctor with special training in veins. A direct primary care or concierge doctor can be a first stop for an evaluation and can refer you to a specialist when needed.
What it is
Clarivein is a brand name for a device used to close off a problem vein. It treats varicose veins, which are stretched, swollen veins. A thin tube called a catheter has a rotating wire tip that mixes a medicine, called a sclerosant, with the blood inside the vein. The medicine irritates the vein wall so the vein seals shut, and blood moves through other healthy veins instead.
Why a doctor might recommend it
Varicose veins can cause aching, heaviness, swelling, itching, or skin changes. A doctor may suggest Clarivein when a vein valve stops working and blood pools in the vein.
How to prepare
Preparation is usually simple.
- Ask which medicines to stop before the procedure, especially blood thinners.
- Wear loose clothing and slip-on shoes the day of the procedure.
- Arrange a ride home if you will receive medicine to help you relax.
What happens during it
You stay awake while the doctor numbs the skin, makes a tiny cut or needle stick, and slides the catheter into the problem vein. As the catheter moves up the vein, the spinning wire tip mixes the sclerosant with the blood, closing the vein. You can usually go home the same day.
Recovery
Most people go back to normal activities within a day or two. Your doctor will likely ask you to wear compression stockings for a set time and to walk often. Avoid heavy lifting and long standing.
Risks and side effects
Clarivein is considered a low-risk procedure, but problems can happen. Possible side effects include bruising, tenderness, and a firm, tender cord where the vein closed. Rarely, the medicine can irritate nearby tissue. Ask your doctor to explain the risks that apply to you.
Who performs it
Vascular surgeons perform Clarivein most often. Some interventional radiologists or other vein specialists also do it. Ask how many they perform each year and what results their patients usually have.
How a direct primary care or concierge doctor fits in
A direct primary care doctor charges a flat monthly fee instead of billing insurance. A concierge doctor usually charges more and often works alongside insurance. Either can be a good first stop for leg symptoms and can refer you to a vascular surgeon or vein specialist for Clarivein.
Common questions
Does the procedure hurt?
Most people feel only the numbing shots and some pressure or vibration from the spinning wire tip. Soreness afterward is usually mild. Pain tolerance differs, so talk to your doctor about what to expect.
Will the vein come back?
The treated vein stays closed permanently in most cases. However, new varicose veins can form over time. This is more likely if you have a family history of vein problems. Some people need more treatment later.
How is Clarivein different from laser vein treatment?
Laser treatment uses heat to close the vein. Clarivein uses a spinning wire and medicine instead. Clarivein usually needs less numbing medicine around the vein. Your doctor can explain which method fits your vein and your health.
When can I drive or exercise again?
Many people drive and return to light activity the next day. Your doctor will tell you when it is safe to lift heavy things or run. Follow the plan they give you, since it depends on your situation.
