Background
BackgroundRecently, it is common for Drug coated balloon (DCB) strategy of femoral popliteal artery disease．We retrospectively analyzed IVUS guided optimal balloon artery ratio（BAR）, and used a receiver operating characteristics (ROC).
Methods
Between January 2018 and Nov 2020, we treated 858 lesions with Endvascular therapy.We selected denovo 101 lesions for single DCB to one lesion. We excluded lesions in which multiple DCB were used for one lesion, and those in which the distance between lesions was closer than 5 cm. Clinical and procedural data of those lesions were analyzed ．The primary endpoint was CD-TLRat 1year.CD-TLR was defined as reintervention at the target lesion due to symptoms or decrease in ankle-brachial index (ABI) ≥20% or >0.15 vs the postproceduralABI.
Results
ResultsAccording to the ROC analysis of BAR for the primary endpoint, Cut off was 0.95 (AUC;0.67) and divided into two groups: Higher Group (>0.95; HG) and Lower Group(<0.95; LG). CD-TLR at 1year of HGand LG were （12% VS 32% ,P= 0.015)．
Conclusion
All lesions were treated with IVUS Guided in this study.Selecting a DCB size that is smaller than the reference vessel diameter measured by IVUS may lead to poor outcomes in the mid-term results.
