Early rupture and degeneration of cryopreserved arterial allografts.
Arterial allografts are used in vascular surgery to solve a major problem: vascular reconstruction in the infected area. To palliate the unavailability and to reduce the risk of viral disease transmission, vascular allografts are currently cryopreserved and stored in tissue banks. In our recent clinical experience, we observed several cases of rupture and degeneration of cryopreserved arterial allografts. All indications are that current cryopreservation protocols are probably the cause for these degenerations.
