- Abstract
Objectives: External color Doppler ultrasonography is reported to be a useful monitoring technique that is simple and noninvasive; however, details of imaging of the transferred free jejunal flap have not been reported. We reviewed our experience using external color Doppler ultrasonography to monitor a transferred free jejunal flap and examined its utility. Study Design: Retrospective study. Methods: Subjects were 43 patients who underwent total pharyngolaryngectomy, reconstruction with a free jejunal flap, and color Doppler ultrasonography before, during, and after surgery between September 2017 and December 2021. Results: During surgery, arterial thrombosis was detected up to 100% with the loss of continuous color signals in the entire circumference. After surgery, the positive predictive value was 100% for each of wiggling movement, dynamic intestinal movement, and continuous color signals in the entire circumference on color Doppler ultrasonography for detecting flap viability. Their negative predictive value was 100%, 7.1%, and 50%, respectively. Conclusions: During surgery, the continuous color signals in the entire circumference sign were useful with 100% negative predictive value for detecting the arterial thrombosis. After surgery, the wiggling movement sign very was useful with 100% positive and negative predictive values, enabling salvage surgery to be performed soon after detection of flap failure.
