There has been one reported case of stroke after ultrasound-guided sclerotherapy when an unusually large dose of sclerosant foam was injected.

Other issues which arise with the use of sclerotherapy to treat spider veins are staining, shadowing, telangetatic matting, and ulceration.
33.
In ultrasound-guided sclerotherapy, ultrasound is used to visualize the underlying vein so the physician can deliver and monitor the injection.
34.
Telangiectatic matting, or the development of tiny red vessels, is unpredictable and usually must be treated with repeat sclerotherapy or laser.
35.
Sclerotherapy can also be performed using microfoam sclerosants under ultrasound guidance to treat larger varicose veins, including the great and small saphenous veins.
36.
These smaller veins can be eliminated with sclerotherapy, a procedure in which caustic material is injected into blood vessels, causing them to shrivel.
37.
Kellawan eliminated Frank's spider vein problem with sclerotherapy, a procedure that involves injecting a chemical solution into the vein to dissolve it.
38.
Treatment can include Endovenous Thermal Ablation using radiofrequency or laser energy, vein stripping, ambulatory phlebectomy, foam sclerotherapy, lasers, or compression.
39.
The first reported attempt at sclerotherapy was by D Zollikofer in Switzerland, 1682 who injected an acid into a vein to induce thrombus formation.
40.
Sclerotherapy is the " gold standard " and is preferred over laser for eliminating large spider veins ( telangiectasiae ) and smaller varicose leg veins.
