How does Sclerotherapy work exactly?
A sclerosant is a medicine that is used to cause injury to the inner vein wall. This injury occurs in a controlled manner, depending on the volume and concentration of the medication used in each site. The medication is inactivated quickly by dilutional effect and interaction with structural components of the vein walls, making the effect localized. The initial injury to the vein wall results in a healing process which causes the vein to literally heal shut over time. This results in shrinkage of the vein wall, and eventually, complete obliteration of the target vein. The medicine is frequently turned into temporary “FOAM”. This process has been shown to significantly improve the treatment results, especially in larger sub-surface veins that could in the past only be treated with surgery. Now, using direct ultrasound guidance we can treat these veins without surgery and achieve more accurate and complete results.
