title: The effects of streptokinase on ischemic flaps.
abstract: Prolonged ischemic periods may inhibit success in microsurgical procedures. Impairment of fibrinolytic activity could be a factor contributing to this problem. Ischemic epigastric flaps in the rat were used as a model to measure the potential of streptokinase to improve blood flow and tissue survival. A moderate but statistically significant improvement in flap survival was observed and is felt to be due to the enhancement of fibrinolytic activity previously impaired by ischemia. Saline irrigation alone in control animals was found to be detrimental to flap survival. Streptokinase might prove beneficial when dealing with an ischemic replant or free flap.
