abstract

  • This study compares the effects on intimal hyperplasia of different methods of manipulating a vein graft before using it as an arterial substitute. Grafts that were denuded of endothelium showed the most intimal hyperplasia, while those that were washed with saline, dilated with saline or crushed did not differ appreciably from each other with respect to the degree of intimal hyperplasia. The hyperplasia was well developed and stabilized at 3 weeks, which coincided with restoration of the endothelial surface. The similarity between the last three methods of graft manipulation suggests that minor endothelial disruption produced at the time of harvesting the vein is equalized after insertion of the vein into the arterial circulation.
