Fluorescein test in the prediction of viability of skin flaps on pigs.
The fluorescein test is widely used in clinical and experimental studies for prediction of the viability of skin flaps. A thorough search of the literature revealed that the accuracy of this test had never been studied. Therefore, this study was designed to evaluate the accuracy of the fluorescein test in predicting the viability of skin flaps. A total of 212 unipedicle porcine skin flaps were used in this study. Statistical analysis demonstrated that the surviving area of the flap was significant greater than the staining area of the flap. We suggest that caution be exercised when the fluorescein dye test is used to assess skin flap viability and that the test be used for an approximate indication and not for an accurate prediction of the surviving flap area.
