What is a contraindication for sclerotherapy treatment?

Sclerotherapy is a treatment method used to eliminate varicose veins and spider veins by injecting a solution directly into the affected veins, causing them to collapse and eventually fade from view. One significant contraindication for this procedure is pregnancy. When someone is pregnant, the body goes through various changes, including hormonal shifts and increased blood volume, which can lead to the development or worsening of venous conditions. Additionally, the safety of sclerotherapy during pregnancy hasn't been well-established, making it prudent to avoid this treatment until after childbirth.

Other factors such as age over 60 or high blood pressure can complicate treatment but are not absolute contraindications. Varicose veins themselves are actually the target of sclerotherapy, indicating that they are not a contraindication. Thus, pregnancy stands out as a condition that distinctly warrants caution against proceeding with sclerotherapy.
