What does endovascular angioplasty with a drug-coated balloon involve?

This is a minimally invasive catheter-based procedure to reopen narrowed or blocked arteries. A thin tube (catheter) is guided through a small incision in the groin or wrist to the affected vessel. A balloon at the tip is inflated to compress the plaque, and a drug-coated balloon (DCB) delivers medication (e.g., paclitaxel) directly to the artery wall to prevent re-narrowing. Unlike stenting, no permanent implant is left behind, which can be advantageous in certain cases.
