Colour Doppler sonography in the preoperative assessment of the vascular pedicle from the anterolateral thigh flap: proposal for a mathematical formula to predict pedicle length

Abstract: IntroductionThe anterolateral thigh flap (ALT) is one of the most commonly used grafts in head and neck reconstructive surgery. In this type of surgery, it is essential that the vascular pedicle be long enough to ensure proper vascular anastomosis. However, it is difficult to accurately estimate the pedicle length preoperatively. In this context, the current study had two aims: (1) to assess the value of colour Doppler sonography (CDS) in the preoperative assessment of the vascular pedicle and (2) to develop a… Show more

“…One study examined the use of preoperative color Doppler sonography with mathematical models to estimate the length of the pedicle, and differentiate anatomical variations. The calculated minimum pedicle length and actual length was congruent in about 75% of cases, and sonography recognized the two anatomical variants of the ALT vasculature in nearly all cases [8]. The experiment reaffirmed the significance of Doppler sonography for ALT flap reconstruction.…”

“…Łuczewski et al propose a mathematical formula based on preoperative Doppler sonography to predict the length of the pedicle of the ALT flap. The authors claim that the intraoperatively measured pedicle length was equal or larger than the estimated length in 73.9% of the cases [ 16 ]. However, the estimated length agreed with intraoperative findings only in 14.54% of the cases.…”

“…A perforator with septocutaneous type is also preferred for faster, safer, and less traumatic dissection 16 . Besides, the vascular pedicle must be long enough to ensure proper vascular anastomosis within the vessels 21 and careful preoperative assessment may avoid the need for later vessel grafting to lengthen the pedicle 22 . What is more, the critical step for preoperative design of ALT flaps is to map the surface location of cutaneous perforators 23 .…”
