High-Frequency Ultrasound in DIEP Flap Breast Reconstruction: Anatomical Insights Without Perfusion Predictive Value

High-frequency ultrasound (HFUS) noninvasively visualizes midline crossing-over vessels critical for DIEP flap vascularization.
All patients showed presence of these crossing-over vessels on HFUS examination preoperatively.
No significant correlation was found between HFUS vascular parameters and indocyanine green (ICG) angiography measures of flap perfusion intraoperatively.
HFUS offers detailed anatomical characterization but currently lacks predictive value for DIEP flap perfusion and outcomes.
