• Three groups of rats were studied. Group 1 rats received 6,000 R of irradiation, group 2 rats received 4,000 R, and group 3 rats acted as a control. Four weeks following irradiation, the femoral artery of each rat was cut and reapproximated using microvascular surgical techniques. Four weeks after surgery, the same femoral artery was evaluated for patency. There was no notable effect of irradiation on the patency of subsequently performed anastomosis of these small (1 mm in diameter) muscular arteries. Radiation effects were obvious on histological examination, but the anatomical and physiological alterations apparently were not severe enough to cause early thrombosis after microsurgical manipulation of these vessels.
