Impact of Baseline and Postprocedural Intravascular Ultrasound Findings on 1-Year Primary Patency After Drug-Coated Balloon Treatment of Femoropopliteal Lesions.

Restenosis after DCB treatment was shown to correlate with CTO, circumferential calcification, and postprocedural MLA as evaluated by IVUS. Moreover, smaller vessel sizes might represent a particular challenge to the DCB strategy due to the difficulty of restoring a sufficient postprocedural lumen area by balloon dilatation.
