What Is Sclerotherapy?

Sclerotherapy is a technique utilizing injections of a prescription medication into spider veins. The use of a sclerosing agent causes the vessel lining to become sticky and the two sides adhere to each other. This coming together of the vessel lining is further promoted through the use of external compression. The combination of the procedure and the recommendations following the treatment causes the blood supply to the specific vessel to be reduced significantly/completely. As a result of the vessel not receiving this blood supply the vessel is reabsorbed into the system through the healing process and the vein disappears in the weeks to come. 

When should sclerotherapy be considered? 

This treatment is recommended to patients that have symptomatic varicosities and/or cosmetic spider veins.

What are the advantages of sclerotherapy? 

Using the sclerotherapy technique the treatment takes approximately 45-60 minutes. The treatment is performed in the office, and requires no time off from work. To compare, surgical treatments (ligation or stripping) are necessary under certain situations. Accompanying surgical treatments can be unsightly, painful scars, and time off from work.

What can be expected from sclerotherapy? 

Sclerotherapy can dramatically the appearance of spider veins. Symptoms resulting from distended veins should disappear. As this treatment involves injections there is the potential for minor local inflammation to occur; usually discomfort is minimal. Bruising may last 3-4 weeks and brownish staining may occasionally last a few months.

Support/compression stockings are recommended for 30 days following treatment.

Serious but rare complications include phlebitis, infection, allergic reaction and skin ulcers. All of which will be discussed in your consultation/assessment prior to treatment.
