Arterial graft preservation

Skin Graft Preservation

o. There are two different cryopreservation protocols used in skin preservation: slow freezing and quick freezing/snap frozen. Slow freezing can be achieved using a controlled-rate cooling apparatus (Blondet et al., 1982). There is an optimum cooling rate for any cell type that produces maximum cell survival. On either side of this optimum, the survival rate falls. In the presence of CPA, a coo...

Viable vein graft preservation.

Homologous vein grafts are becoming increasingly useful in patients without suitable autologous saphenous veins for peripheral arterial bypass procedures [4, 81. However, fresh veins are the only tissue that has been used successfully in homograft vascular reconstruction in terms of long-term patency [4]. The advantages of a reliable method of long-term storage of viable vein segments and the u...

Emerging concepts in liver graft preservation.

The urgent need to expand the donor pool in order to attend to the growing demand for liver transplantation has obliged physicians to consider the use of suboptimal liver grafts and also to redefine the preservation strategies. This review examines the different methods of liver graft preservation, focusing on the latest advances in both static cold storage and machine perfusion (MP). The new s...

Liver graft preconditioning, preservation and reconditioning.

Liver transplantation is the successful treatment of end-stage liver disease; however, the ischaemia-reperfusion injury still jeopardizes early and long-term post-transplant outcomes. In fact, ischaemia-reperfusion is associated with increased morbidity and graft dysfunction, especially when suboptimal donors are utilized. Strategies to reduce the severity of ischaemia-reperfusion can be applie...
