Abstract：Objective: To evaluate the application of color Doppler flow imaging(CDFI) in the medial sural artery perforator(MSAP) flap. Methods: CDFI and acoustic Doppler ultrasound were compared in evaluating the number, location, diameter of perforator and main vascular traveling by single-blind trials, the data were compared with intraoperative anatomical finding. Results: In this study eight flaps were transplanted, 24 perforating arteries were involved. Totally 22 MSAPs were found by preoperative CDFI, and 17 by acoustic Doppler ultrasound, 2 and 6 perforators were misdiagnosed respectively, 2 and 7 were missed respectively. There were significant statistical differences between these two methods(P＜0.05). The measurement of diameter by CDFI have no significant statistical difference with the finding in operation(P＞0.05), and 16 vascular bifurcation detected by CDFI was accordance with that found in intraoperative anatomy. Flap survived well with no significant postoperative complications in 8 cases. Conclusion: CDFI is very useful for preoperative planning of medial sural artery perforator flap and increase the reliability of the perforator flap.
