Abstract

The CIVILIAN study prospectively compared Chocolate balloon (CLP), conventional balloon (CP), and sequential balloon pre-dilation (SEP) in 435 patients with femoropopliteal occlusive disease treated by DCB. Results showed CLP significantly reduced bailout stenting rates (18.1% vs. 30.1%, p=0.011) and simplified procedures compared to SEP.

Introduction

Optimal vessel preparation is critical for DCB efficacy. This registry analyzed CLP’s ability to minimize dissection and stent dependency while maintaining procedural simplicity.

Case Studies

Bailout Stenting

CLP: 18.1% vs. CP: 30.1% (p=0.011).

Maximal Pre-dilation Balloon Diameter

CLP: 4.74±0.52 mm vs. CP: 4.36±0.64 mm (p<0.001).<>

12-Month MAE

13-CLP: 7.8% vs. SEP: 9.7% (p=0.436).

Conclusion

1.CLP reduces bailout stenting and offers procedural simplicity.

2.SEP provides larger lumens but requires complex techniques.

3.Long-term follow-up will clarify DCB sizing benefits.
