Sclerotherapy Spider Vein Injections
What is sclerotherapy?
Sclerotherapy (also known as chemical ablation) is typically used to treat smaller veins and branches of large veins, such as spider veins and reticular veins. Sclerotherapy involves the injection of a sclerosant agent into problem veins, which causes a chain of biological reactions that eliminate the target veins.⁶
How do sclerotherapy vein injections work?
The injection kit and sclerosant formulation are prepared
A small needle is inserted into the target vein
Sclerosant is injected, causing the vein to respond immediately
Sclerosant causes vein irritation, dehydration, and destruction
Are sclerotherapy vein injections clinically proven?
Clinical evidence supports the use of sclerotherapy agents, including Asclera, to eliminate spider veins and reticular veins. In the EASI study, approximately 85% of individuals treated with Asclera were still satisfied with treatment six months afterwards.⁷
While other providers may offer laser therapy to treat spider veins, we choose to use sclerotherapy for its proven advantages over laser therapy, including:
(1) the ability to treat larger feeder veins and veins that lie farther underneath the surface of the skin ⁹
(2) faster resolution and less pain than laser treatment ⁸⁻⁹
(3) sclerotherapy usually only requires one or two treatment sessions for complete resolution, while laser typically requires more ⁹
In addition to treating cosmetic vein problems, it is common practice to use sclerotherapy after varicose vein treatment (ClosureFast™ thermal vein closure or VenaSeal™) to eliminate small vein branches if needed.²
