We were challenged by the experience of one patient reoperation for a bioprosthetic bovine pericardium degenerative stenosis, 24 years after implantation. This bioprosthesis was implanted due to tricuspid valve bacterial staphylococcal endocarditis after septic abortion.

BACKGROUND Despite marked improvements in pancreatic surgery, the high incidence and morbidity of pancreatic leak after resection has remained unchanged. The current study investigated the safety and efficacy of bovine pericardium wrapping stump after distal pancreatectomy in a porcine model. METHODS Thirty-two swine were randomly assigned to control and experiment groups to undergo conventio...

Many different materials are available for grafting during surgery for Peyronie's disease (PD). To study the outcomes associated with the use of a lyophilized bovine pericardium graft (Peri-Guard®) to repair tunical defects in patients with PD, descriptive study of 43 patients with disabling penile curvature was performed. Curvature was measured before and after the intervention using a standar...

Scientific progress shall ultimately boost the current acceptance level for conservative aortic valve surgery. The present text aimed to report the 23-year long-term follow-up of one patient operated with bovine pericardium cusp extension. Growing confidence in the efficacy of the operation will allow a more expeditious indication for surgical treatment, as is already the case in mitral valve r...

Certain styrenic thermoplastic block copolymer elastomers can be processed to exhibit anisotropic mechanical properties which may be desirable for imitating biological tissues. The ex-vivo hemocompatibility of four triblock (hard-soft-hard) copolymers with polystyrene hard blocks and polyethylene, polypropylene, polyisoprene, polybutadiene or polyisobutylene soft blocks are tested using the mod...

Heart valve prostheses are used to replace native heart valves which that are damaged because of congenital diseases or due to ageing. Biological prostheses made of bovine pericardium are similar to native valves and do not require any anticoagulation treatment, but are less durable than mechanical prostheses and usually fail by tearing. Researches are oriented in improving the resistance and d...

Gunshot wound injury to the external genitalia is relatively uncommon. However, if a testis isaffected in such a case, early surgical exploration should be carried out. A 16-year-old boy presented with right testicular rupture. Tunica albugineal defect could not be closed primarily. We used a Tutoplast® processed bovine pericardium to repair the defect of tunica albuginea. At his 3-month follow...
