First-in-man results of a novel vascular graft coated with resorbable polymer for aortic reconstructions--a multicenter, non-randomized safety study.

Objectives: The purpose of this "first-in-man" study was to investigate the safety of a novel vascular polyester prosthesis coated with a resorbable polymer and free of any animal-based coating agents such as gelatin or collagen.

Methods: In a nonrandomized first-in-man multicenter safety study, the frequency of perigraft seroma (PGS) as the primary endpoint was studied in consecutive patients undergoing aortic reconstructions. The follow-up control to study the primary endpoint was intended at 3 months under routine clinical conditions.
