Long-term storage of Ice-free preserved vascular allografts

Abstract

Objective: Arterial allografts are routinely employed for reconstruction of infected prosthetic grafts. The existing conventional frozen cryopreservation (CFC) demand complex and expensive infrastructure. Ice-free cryopreservation (IFC) might offer an attractive alternative resulting in a facilitated and cost-effective processing, storage and shipping method. Objective of this study was to determine structural integrity and haemocompatibility of long-term preserved IFC vascular allografts.
