Scanning electron microscopic study of microvascular anastomoses on irradiated vessels: long-term effect of irradiation.

A study was performed to determine the effect of preoperative irradiation on microvascular arterial anastomoses. The study focused on microthrombi and epithelial regeneration. Using scanning electron microscopy (SEM), a clear difference was seen comparing nonirradiated to irradiated vessels. No difference was found between short- and long-term effects of irradiation.
