Sclerotherapy is a form of treatment where a doctor injects medicine into blood vessels or lymph vessels that causes them to shrink. It is commonly used to treat varicose veins or so-called spider veins.
The procedure is non-surgical, requiring only an injection. It can also be used to treat blood and lymph vessel disorders that cause these vessels to form incorrectly.
Sclerotherapy uses an irritating solution called a sclerosant, which is injected directly into a vein or lymph vessel. The solution irritates the vessel, causing it to swell. This swelling cuts off the flow of blood or lymphatic fluid and the vessel shrinks.
People with spider veins should consider sclerotherapy when:
Phlebectomy (also known as microphlebectomy, ambulatory phlebectomy, or stab avulsion) is a technique to remove varicose veins. In this procedure, several tiny cuts (incisions) are made in the skin through which the varicosed vein is removed. Stitches usually are not required.
This procedure typically does not require a stay in the hospital. It may be done in your doctor’s office under light sedation with local anesthesia.
Phlebectomy might be done along with another treatment for varicose veins, including ligation and stripping, laser treatment, or radiofrequency treatment.
Phlebectomy can help improve the cosmetic appearance of skin after treatment.1 But this procedure is less likely to fix varicose veins when the leg veins are not working well. Because that is the case for most varicose veins, this procedure is usually used along with other treatments, such as ligation and stripping, laser treatment, or radiofrequency treatment.
