Comparison of Biografts and Artificial Fabrics for the Patch-graft of Diaphragmatic Defect in Cats

Abstract

Clinical usefulness of four different kind of patch grafts for the diaphragmatic defect was compared in the cat. We evaluated two biograf is (glutaraldehyde treated canine pericardium and denacol treated canine pericardium), and two artificial fabrics (polyester nonwoven fabric and chitin-polyester nonwoven fabric complex) in experimentally made diaphragmatic defects (3×3cm) using 12 healthy cats. One month after the grafting with biografts, graft materials and surrounding diaphragm tissue united well and minimum inflammation was investigated 12 months after the grafting. Artificial fabrics and surrounding diaphragm tissue also united well, however, inflammation had sustained 12 and 24 months after the grafting.
