The use of lyophilized bovine pericardium (Tutopatch®) in the management of third nerve palsy following prior conventional strabismus surgery – a case series

To study the secondary management of strabismus due to third nerve palsy using bovine pericardium (Tutopatch®) when previous conventional surgical therapy had failed. Review of our clinic records of selected patients with third nerve palsy, in whom residual deviation had been managed using Tutopatch® after previous surgical correction. The squint angle was measured preoperatively, and at 1 day, 3 months, and if possible 6 months postoperatively. Nine patients were enrolled in this study. One...

Infrared Spectroscopic Verification of a α-Helical Collagen Structure in Glutaraldehyde-Free Crosslinked Bovine Pericardium for Cardiac Implants

The degeneration of heart valve bioprostheses due to calcification processes is caused by the intercalation of calciumhydroxyapatite in pericardium collagen bundles. Variations of the protein secondary structure of biomaterials according to preparation are relevant for this mineralization process and thus the structural characterization of innovative bioprostheses materials is of great importance. The gold standard for prostheses preparation is glutaraldehyde (GA)-fixation of bovine pericardium...
