مرض الشرايين الطرفية

A DCB delivers paclitaxel to the arterial wall during angioplasty, inhibiting smooth muscle proliferation causing restenosis. Unlike stents, DCBs leave no permanent implant.

Rotational atherectomy is used for heavily calcified peripheral lesions that resist balloon dilatation. The high-speed burr removes hard plaque as vessel preparation before stenting or DCB.
