Here are some recent videos of actual patients. These are unretouched. The results of injections can be variable.
Sclerotherapy is the injection of a solution into offending veins, such as "spider veins" and even some small varicose veins. This procedure is performed in the office, is relatively painless, and may be repeated as necessary to remove the appearance of unsightly varicosities. Injection is limited to veins less than 3 mm in diameter and is generally not as successful in larger veins. Complications are rare but can include a deep venous thrombosis (blood clot in the deep veins) or skin ulceration. A careful approach to sclerotherapy has resulted in complications of much less than 1%.
