Summary:Polyurethane sheet (Thoratec Laboratories Corporation, USA) is compliant material. It is composed of three layer and has high tensile strength and absolute tightness for air and fluids. In eight mongrel dogs chest wall defect (6×6 cm) was created by resecting 2 or 3 ribs. Then chest wall was reconstructed with the sheet. After implantation, paradoxical movement of the chest wall was not observed. One to nine months after implant, these sheets were harvested. Adhesion of the sheets to the lung was slight to moderate. On light microscopic examination, smooth fibrous tissue with collagen, mild foreign-body reaction and mild scar formation were observed. On scanning electron micrograph, mesothelial cells were not detected. In conclusion polyurethane sheet is cosidered to be applicable to chest wall reconstruction.
