Conclusion

- An in vitro study of cryopreserved and fresh human arteries: a comparison with ePTFE prostheses and human arteries studied non-invasively in vivo

The cryopreservation technique we used did not modify the viscous and elastic properties of fresh arteries. The cryopreserved segments maintained similar viscous and elastic properties when compared with the arteries of normotensive, ambulatory subjects. The viscous and elastic behaviour of ePTFE conduits is very different from those of arteries.
