Although the autogenous vein graft is the most reliable in the fields of microvascular
reconstruction, the microvascular allograft and microvascular prosthesis have been
developed to be substitute for autogebous vein because it has many problems. In many
experimental study have been reported highly variable patency rate and its
thrombogenitic property of microvascular allogragt. Especially, antigenicity of the
homogenous vessels and immune reaction-induced thrombosis are main cause of
homogenous microvascular anastomosis failure. For thant reason, several investigators
have attempted to reduce the antigenicity and improve the patency rate of microvascular
allograft.
The purpose of this study was to observe the healing process in applying frozen
arterial allograft in the rats. In order to perform this study, 27 Sprague-Dawley rats,
weighing 300gm or more selected. 12 carotid arterial anastomoses were performed in the
rats by suing microvascular end-to-end anastomosis as control group and 15
frozed(-196¡É) arterial allografts were implanted into the carotid artery in the rats by
using microvascular anastomosis as experimental group.
The experimental rats were sacrificed on the 1st, 3rd, 7th, 14th, 28th, 56th day after
operations. For scanning electron microscopic study fixation was performed by perfusion
of 2.5% glutaraldehyed-2% paraformaldehyed in 0.1M phosphate buffer at pH7.3. The
specimens were post-fixated in 1% osmium tetraoxied for 2 hours, washed with
cacodylate buffer, dehydrated in a series of ascending ethanol baths, critical point critical
point dried, coated with gold in a vacuum evaporator, and observed sith a scanning
electron microscope(JEOL, JSM-840-A, 20kV).
For histologic examination taken specimens were embedded in paraffin, sectioned 6-8
¥ìm in thickness. The specimens were stained with hematoxylin-eosin stain method,
examined under light microscope.
The results were as follows :
1. The patency rate of control group was 92% and experimental group was 86%.
2. Endothelial cells regeneration at the anastomosis site of both group was partially
appeared on the 1st week after experiment.
3. On the 2nd week after experiment, anastomosis site was completely covered with
regenerated endothelial cell in both group, and the endothelial cell proliferated toward the
graft at experimental group.
4. On the 4th, 8th week after experiment, the grafted artery was partially covered
with endothelial cell at experimental group.
