drug-coated balloon
Also written as: DCB — Drug-Coated Balloon
Specialized balloon catheter coated with antiproliferative medication to prevent restenosis.
Full Definition
A drug-coated balloon (DCB) is an angioplasty balloon catheter with its surface coated with antiproliferative drugs, typically paclitaxel or other cytostatic agents. When inflated during angioplasty, the drug is transferred directly to the vessel wall to inhibit smooth muscle cell proliferation and reduce the risk of restenosis. DCBs are particularly useful for treating in-stent restenosis, small vessel disease, and bifurcation lesions where stent placement may be problematic. The technology allows for drug delivery without leaving a permanent metallic implant in the vessel.
Usage
Usage note: May be abbreviated as DCB after first use; hyphenate the compound adjective.
