Bovine pericardium retail preserved in glutaraldehyde and used as a vascular patch
BACKGROUND In this study we evaluated the performance of bovine pericardium preserved in glutaraldehyde used as a vascular patch. METHODS Fourteen young pigs, six females and eight males, weighting 10.3 - 18.4 kg were used in our study. We implanted three remnants in each pig, two in the abdominal aorta and one was juxtaposed to the peritoneum. The smooth face (SF) and rough face (RF) of each...
متن کاملComparison of Lyophilized Glutaraldehyde-Preserved Bovine Pericardium with Different Vascular Prostheses for Use as Vocal Cords Implants: Experimental Study
This study compared the use of lyophilized glutaraldehyde-preserved bovine pericardium (LGPBP), polytetrafluoroethylene (PTFE), polyethylene terephthalate (PET), and Teflon felt (TF) as implants for vocal cords (VC) medialization and aimed to assess the endoscopic, macroscopic, and microscopic VC changes after medialization in a canine model. In 18 mongrel dogs, the right VC were medialized wit...
متن کاملLyophilized glutaraldehyde-preserved bovine pericardium for experimental atrial septal defect closure.
A variety of patch materials has been used to close large atrial septal defects (ASD). Autologous pericardium and glutaraldehyde-preserved bovine pericardium are the most used. Lyophilized bovine pericardium has not been tested inside the cardiovascular system. The aim of this work was to study the behaviour and effectiveness of lyophilized glutaraldehyde-preserved bovine pericardium in ASD clo...
متن کاملAlkaline phosphatase activity of glutaraldehyde-treated bovine pericardium used in bioprosthetic cardiac valves.
Bioprosthetic valves fail frequently because of pathological mineralization, a process that begins in cell remnants of the glutaraldehyde (GLUT) fixed tissue. Other pathological cardiovascular calcification and physiological mineralization in skeletal/dental tissues are both largely initiated in cell-derived membranous structures (often called "matrix vesicles"), and the enzyme alkaline phospha...
متن کاملEffect of SDS-based decelullarization in the prevention of calcification in glutaraldehyde-preserved bovine pericardium: study in rats.
OBJECTIVE The aim of study was to investigate the SDS-based decellularization process as an anticalcification method in glutaraldehyde-preserved bovine pericardium in subcutaneous rat model. METHODS Pericardium samples with 0.5 cm² area were divide in four groups: group GDA: 0.5% glutaraldehyde-preserved pericardium (GDA); group GDA-GL: GDA + 0.2% glutamic acid (GL); group D-GDA: decellulariz...
