Comparison of Intravascular Ultrasound-Guided vs. Angiography-guided Angioplasty and Dual-antiplatelet v. Triple-antiplatelet Therapy for Outcomes of Drug-coated Balloon in the Treatment of Femoropopliteal Artery Disease (IVUS-DCB)

Angioplasty using drug-coated balloon (DCB) will be performed in standard manner. IVUS evaluation will be performed before predilation and after DEB treatment. In cases of stent implantation, additional IVUS evaluation will be performed after stenting. All lesions will be predilated using a plain balloon with a diameter 1 mm smaller than vessel size. Selection of DCB diameter will be chosen on the basis of IVUS measurement. Implantation of stents will be left to the operator's decision after reviewing IVUS findings after the DCB treatment. Generally, in presence of ≥ 50% residual stenosis or flow limiting dissections, implantation of stents is recommended.
