Drug eluting balloons (DEBs) represent an important advance in the endovascular treatment of peripheral arterial disease. Unlike conventional angioplasty balloons, DEBs are coated with an antiproliferative agent, most commonly paclitaxel, which is released directly into the arterial wall during balloon inflation. This local drug delivery suppresses neointimal hyperplasia, the healing response responsible for restenosis, offering improved long-term patency compared to plain balloon angioplasty.
At Perth Vascular Clinic, drug eluting balloon angioplasty is used selectively for lesions at high risk of restenosis, including those in the superficial femoral and popliteal arteries. The technique combines the immediate lumen gain of conventional angioplasty with a sustained biological effect that continues to protect the vessel wall after the balloon is removed. For carefully selected patients, this approach can reduce the need for repeat intervention and support durable outcomes in symptomatic peripheral vascular disease.

Frequently Asked Questions
Drug-eluting balloon angioplasty is an endovascular technique used to treat narrowed peripheral arteries. A balloon coated with an antiproliferative drug (typically paclitaxel) is inflated at the site of the blockage. The drug is transferred to the artery wall as the balloon inflates, inhibiting the scar tissue response that can cause re-narrowing after standard angioplasty.
