During sclerotherapy, what can an improper air to sclerosant ratio lead to?

An improper air to sclerosant ratio during sclerotherapy can indeed lead to poor treatment outcomes. Sclerotherapy is a procedure used to treat varicose veins and spider veins by injecting a solution (sclerosant) that causes the targeted veins to collapse and eventually fade from view. Achieving the correct concentration of sclerosant is crucial to ensure effective vein closure and minimize potential complications.

When the ratio of air to sclerosant is not optimal, the sclerosant may not be delivered effectively to the intended site, resulting in inadequate treatment of the vein. This can lead to persistent vein visibility, recurrence of venous issues, or complications that require additional treatments.

Other options may pose risks associated with improper technique and preparation, but the primary and most direct consequence of an incorrect air to sclerosant ratio is inefficacy in the treatment process itself.
