Hosoyama K, et al. - This study sought to evaluate the safety and durability of basic fibroblast growth factor-incorporated biodegradable polyglycolic acid (PGA) felt. findings suggested that for reinforcement in aortic surgery, this biodegradable felt was as safe and durable as conventional felt. PGA felt reinforcement resulted in attenuation of juxta-anastomotic aortic dilatation that could provide more beneficial effects on long-term outcomes.
