When is a drug-eluting balloon used, and how does it differ from a stent?

• A. Used for all lesions to avoid any implant; releases antiproliferative drug and leaves a scaffold.
• B. Placed for immediate stent placement.
• C. Used for lesions that still require a permanent metallic framework.
• D. Used for certain lesions to avoid leaving a permanent implant; releases antiproliferative drug but does not leave a scaffold, unlike a stent.

Answer: (D)

Drug-eluting balloons are used when you want to treat a lesion with antiproliferative therapy but without leaving a permanent implant behind. The balloon is coated with an antiproliferative drug and, during inflation, the drug transfers to the vessel wall to suppress neointimal hyperplasia and reduce restenosis. After the balloon is deflated and removed, there is no metallic scaffold left in the artery. This is different from a stent, which provides immediate mechanical scaffolding to hold the vessel open and leaves a permanent metal framework in place. The DEB’s advantage is avoiding a lasting implant in select situations, such as small vessels, bifurcations where a stent might complicate future interventions, or scenarios where adding another layer of metal is undesirable.
