Is it appropriate to have sclerotherapy (injections) without a Venous Ultrasound?

Varicose and spider veins are usually visible, but the underlying cause that is venous insufficiency can only be diagnosed with a Venous Ultrasound. It is inappropriate to initiate any kind of treatment before your vascular surgeon rules in or rules out venous insufficiency and its severity, to formulate a complete treatment plan, targeted to the specific problem.
