The thermic vascular anastomosis (TVA). III. Analysis by histology.

In 48 Sprague Dawley Wistar rats Thermic Vascular Anastomoses were analyzed by histology 1, 10, and 30 days, 6 and 18 months postoperatively. Fibrin glue turned out to be a valuable additional fixative, effective in preventing ruptures of the anastomoses. It did not modify the formation of a pseudo-intimal layer of connective tissue between the original vascular ends. The healing process of TVAs is worked out; references to earlier studies describing microvascular procedures with fibrin glue application are made.
