Abstract
Histopathological features of the anastomotic vessels
were studied after microsurgical anastomoses in the
femoral vessels of 40 rats.
The observation performed under light and electron
microspes were summarized as follows
1. Endothelial linings were absent at the anastom
。ti c sites and adjacent regions although the internal
elastic membranes remained intact below the missing
intimal layer. No endothelial recovery was seen during
the 2-week follow-up period in this study.
2. The anastomotic vessels suffered some degree of
medial necrosis, and it occured usually along the cut
vessel edge or around the suture of the anastomotic
sites. The necrotic area consisted of the bulk of
degenerating smooth muscle cells with a few of
macrophages and fibroblasts, and it was then replaced
by collagenous fibers and fibroblasts.
3. Incorrect apposition of the cut vessel edge were
often associated with the mural thrombus. Repair
then with organization occured by the ingrowth of
small capillary loops from the vessel wall, and recanalization
commenced
