Recognition, context, and distinction
What does it do, and where will I see it?
Use & procedural context
Detergent sclerosant (STS), often foamed, for treating venous malformations and varices. Typical procedural contexts include venous malformations, varicose veins, and pelvic venous disorders.
What most clearly distinguishes it from similar devices?
Key distinctions
STS is a detergent sclerosant rather than a mechanical embolic; it may be delivered as liquid or prepared foam depending on the target venous or malformation workflow.
