What share of injected veins clear per session?

The share of veins cleared per session can decide whether a quote covers one visit or several, so the figure matters before you pay.

How much clears in one session

A wide range, with a small group who see no change. RadiologyInfo.org says each sclerotherapy session typically results in elimination of 50 to 80 percent of the injected veins. It also says a few (less than 10 percent) of people who have sclerotherapy do not respond to the injections at all.

Reading the 50 to 80 percent range

Read the range as a spread, not a promise. At 50 percent, half of the injected veins are not eliminated by that session. At 80 percent, one in five is not.

The source does not explain what moves a person toward the low or high end, so this page does not either. The figure is also about the injected veins, which means veins you did not have injected are outside it.

The question that makes a quote firm

Ask whether the quoted figure is for one session or for a course. Then ask what happens, and what it costs, if a follow-up session is needed.

Three pages add detail: a patient page on sclerotherapy, the plastic surgeons' page on spider vein treatment and their page on recovery. A Des Plaines clinic can say where its own patients tend to land.

What an average cannot tell you

A published average describes many sessions, not yours. It cannot predict your result, and it is not a price. Let the consultation and a written quote supply those.
