Bypassing the atherosclerotic coronary arteries with autologous...

The shape of a bypass graft plays an important role on its efficacy. Here, we investigated flow through two vascular graft designs-with and without cuff at the anastomosis. We conducted Digital Particle Image Velocimetry (DPIV) measurements to obtain the flow field information through these vascular grafts. Two pulsatile flow waveforms corresponding to cardiac cycles during the rest and the exc...

Autologous fat grafting is commonly utilised to reconstruct soft tissue defects caused by ageing, trauma, chronic wounds and cancer resection. The benefits of fat grafting are minimal donor site morbidity and ease of availability through liposuction or lipectomy. Nonetheless, survival and longevity of fat grafts remain poor post-engraftment. Various methods to enhance fat graft survival are cur...

The anatomical and histological development of the graft union in splice grafting hazelnut (Corylus avellana L.) was examined. One-year suckers were used as rootstock scion materials. Grafting done manually first week December. grafted plants kept for 28 days at 26-28 °C 70-80% relative humidity conditions. cross longitudinal sections with a thickness 12-20 microns taken from area by rotary mic...

OBJECTIVE To study morphofunctional alterations induced by brief pressure increases in human saphenous veins utilized in coronary artery bypass grafting. METHOD Saphenous veins of 20 patients undergoing coronary artery bypass grafting, were distributed into four experimental groups, control, 100 mmHg, 200 mmHg and 300 mmHg, and submitted to pressure distention over 15 seconds using Krebs solu...

BACKGROUND The issue of superiority of single internal thoracic artery grafting versus bilateral internal thoracic artery grafting remains unresolved. The aim of this study was to compare the long-term outcome of single and bilateral internal thoracic artery grafting with concomitant saphenous vein grafting for multivessel coronary artery bypass grafting. METHODS Between March 1985 and April ...

Although vascular bypass grafting remains the mainstay for revascularization for ischemic heart disease and peripheral vascular disease, many patients do not have healthy vessels suitable for harvest. Thus, prosthetic grafts made of synthetic polymers were developed, but their use is limited to high-flow/low-resistance conditions because of poor elasticity, low compliance, and thrombogenicity o...

Abstract Polyethylene terephthalate (PET) fibers and fabrics are widely used for medical device applications such as vascular anterior cruciate ligament prostheses. Several years ago, we began functionalizing PET using anionic polymers to enhance their biocompatibility, cell adhesion, proliferation functional performance Polymer functionalization followed a grafting-from process from virgin sur...
