A best evidence topic in thoracic surgery was written according to a structured protocol. The question addressed was: 'Is storage of saphenous vein grafts in autologous whole blood prior to coronary artery bypass grafting (CABG) more effective than storage in saline in preserving graft function?' Altogether more than 580 papers were found using the reported search, of which, 10 represented the ...
Objective: Autologous osteochondral transplantation (OCT) is an option to treat articular cartilage defects. However, poor graft integration at the cartilage defect/graft interface and secondary graft degeneration limit the use of autologous OCT. Cell sheet engineering offers hope in regenerative medicine. The purpose of this study was to evaluate the effect of synovium derived mesenchymal stem...
A highly osteogenic hybrid bioabsorbable scaffold was developed for bone reconstruction/augmentation. Through the use of a solid free-form fabrication technology, a bioabsorbable polycaprolactone (PCL) cage scaffold with a desired size and shape was produced and then filled with osteogenic bone graft particles, that is, morselized autologous bone chips. A rabbit total lamina defect model was ch...
Biosynthetic nerve grafts are desired as alternative to autologous nerve grafts in peripheral nerve reconstruction. Artificial nerve conduits still have their limitations and are not widely accepted in the clinical setting. Here we report an analysis of fine-tuned chitosan tubes used to reconstruct 10 mm nerve defects in the adult rat. The chitosan tubes displayed low, medium and high degrees o...
Treatment of large bone defects poses a real challenge to the orthopaedic surgeon. The surgeon often times calls on creativity in the form of bone graft substitutes to help mend large bone defects. The bone graft substitutes used today include inorganic compounds such as calcium phosphate, osteoconductive composites which act as a scaffold to allow for new bone growth, and some may include oste...
Cardiovascular disease is the leading cause of morbidity and mortality in Western society. More than 1 million arterial bypass procedures are performed annually in the United States, where either autologous veins or synthetic grafts are used to replace arteries in the coronary or peripheral circulation. Tissue engineering of blood vessels from autologous cells has the potential to produce biolo...
Advances in regenerative therapy have sparked significant interest the field of auricular reconstruction for congenital microtia. Congenital microtia is a rare deformity characterized by underdevelopment or absence external ear. Traditional surgical approaches using autologous grafts artificial implants limitations. Regenerative offers innovative solutions leveraging tissue engineering, biomate...
