Duplex ultrasound allows accurate preoperative flap planning through mapping of perforator
location and anatomy. In the hand and upper extremity, where thickness of the subcutaneous
fat is less compared with other areas of the body, color Doppler ultrasound is particularly
sensitive for analyzing the location and characteristics of perforators. In this study,
we will first review evidence on use of ultrasound in flap planning. Second, we will
provide a technical guide on ultrasound settings for preoperative flap planning. Finally,
we will discuss case examples that show the use of ultrasound for accurate perforator
mapping to facilitate rapid flap harvest. Color Doppler ultrasound is inexpensive
and readily available to be incorporated into the armamentarium of the hand surgeon
for preoperative flap planning.
