Lessons Learned Regarding Handling and Deployment of the Absorb Bioresorbable Vascular Scaffold in Infrapopliteal Arteries.

PURPOSE

To describe relevant technical details with which to facilitate safe and effective use of the Absorb coronary bioresorbable vascular scaffold (BVS) in lower extremity arteries.

TECHNIQUE

The Absorb BVS is a balloon-expandable, poly-l-lactide structure covered in a poly-d,l-lactide bioresorbable polymer that contains the antiproliferative drug everolimus. As a polymeric structure, it has a number of unique physical, handling, and imaging properties that may differ from metallic stents and pose a challenge to the interventionist. Attention must be paid to lesion selection, preparation, scaffold sizing, deployment, and postdilation to achieve optimal outcomes. A detailed description of these issues and deployment techniques is offered based on experience using this BVS in below-the-knee arteries.

CONCLUSION

The Absorb BVS may have application in the infrapopliteal circulation; however, its unique properties warrant careful consideration before use in the lower limb.
