A scanning electron-microscopic study of the healing of microvascular anastomoses made by invagination.
Anastomoses were prepared on the superior mesenteric artery of rats with invagination technique. The healing process was monitored by scanning electron microscopy. After the thrombotic and degenerative signs of the first three days, significant endothelial regeneration was observed by the end of the first postoperative week. Consequently, the denuded media surface was covered by endothelium by the 3rd week.
