Bovine pericardium (Tutopatch) wrap for hydroxyapatite implants

Abstract

Purpose To evaluate bovine pericardium (Tutopatch s ) as a wrapping material for hydroxyapatite implants in patients undergoing enucleation for uveal melanoma. Method Prospective cohort study of patients who had enucleation for uveal melanoma between January 2003 and August 2003 were included in the study. Any patient with less than 3 months follow-up was excluded. Enucleation was performed under general anaesthesia followed by insertion of hydroxyapatite implants wrapped in bovine pericardium (Tutopatch). The recti muscles were sutured directly to the wrap. The tenon's capsule and conjunctiva were closed in two layers. A conformer was inserted at 1 week and artificial eye at 2-3 months. The patients were followed up regularly and were assessed for cosmetic result, exposure of implant, and the need for any further surgical procedures. Results A total of 19 patients (seven male and 12 female) were included in the study. Median age at diagnosis was 63 years (range 38-80 years). Median follow-up was 26 months (range 22-30 months). No patient developed postoperative complications of wound dehiscence. The overall cosmetic result was excellent in all the patients. The rate of postoperative complications compared favourably with published data using other wrapping materials/implants. Conclusion Tutopatch s is a safe wrapping material for hydroxyapatite orbital implants in patients undergoing enucleation for uveal melanoma.

Bovine Pericardium Membrane (Tutopatch) Combined With Solid Platelet-Rich Plasma for the Management of Perforated Corneal Ulcers

“…21 The wrap of hydroxyapatite implants with Tutopatch has been suggested as a safe alternative in patients who undergo enucleation for uveal melanoma, with a low rate of complications and a decreased surgical time compared to the wrap with autologous tissue that needs to be harvested. 22 In glaucoma surgery, a double layer of Tutopatch has been suggested to be useful for the implantation of an Ahmed valve in a patient with anterior necrotizing scleritis. 23 Although perforations were small (0.5-1.5 mm) and the standard treatment for them could be corneal gluing with bandage contact lens, we preferred to use the Tutopatch because of the big area of corneal melting surrounding the perforation.…”

Complications due to bovine pericardium used to cover acrylic implants after enucleation and tubes of aqueous devices

“…Complications due to bovine pericardium used to cover acrylic implants after enucleation and tubes of aqueous devices Bovine pericardium has been described for wrapping of hydroxyapatite implants [1][2][3][4][5] and Ahmed devices. Owing to a shortage of human scleral graft (HSG), we decided to switch to tutopatch for coverage of acrylic implants after enucleation and aqueous devices.…”
