Iliac Anastomotic Stenting With a Biodegradable Poly-L-Lactide Stent: A Preliminary Study After 1 and 6 Weeks

Abstract

Biodegradable PLLA stents showed higher thrombogenicity and reduced patency compared to metal stents during early follow-up. Although ASA and clopidogrel prevented thrombotic occlusion, the increased inflammatory response and neointima formation remain major concerns of PLLA stents. A solution to this problem might be the incorporation of anti-inflammatory drugs into the PLLA stent.
