Evaluation of properties for Carbothane™ 3575A-based electrospun vascular grafts in vitro and in vivo.
Bioengineered vascular grafts have emerged as a promising alternative to the treatment of damaged or occlusive vessels. It is thought that polyurethane-based scaffolds possess suitable hemocompatibility and biomechanics comparable to those of normal blood vessels. In this study, we investigated the properties of electrospun scaffolds comprising various blends of biostable polycarbonate-based polyurethane (Carbothane™ 3575A) and gelatin. Scaffolds were characterized by scanning electron microscopy, infra-red spectroscopy, small-angle X-ray scattering, stress-loading tests, and interactions with primary human cells and blood. Data from in vitro experiments demonstrated that a scaffold produced from a blend of 5% Carbothane™ 3575A and 10% gelatin has proven to be a suitable material for fabricating a small-diameter vascular graft. A comparative in vivo study of such vascular grafts and ePTFE grafts implanted in the abdominal aorta of Wistar rats was performed. The data of intravital study and histological examination indicated that Carbothane-based electrospun grafts outclass ePTFE grafts and represent a promising device for preclinical studies to satisfy vascular surgery needs.
