Abstract

Objective:This study aims to compare the major anatomical aspects among anterolateral thigh, parascapular and lateral arm flaps.Methods:Sixty flaps were dissected in 20 human cadavers, comparing their vascular pedicle length, flap thickness and arterial/venous pedicle diameters.Results:The vascular pedicle length (from the origin of the vascular pedicle to its entry into the skin flap) of anterolateral thigh flap (13.43 ± 3.92 cm, lateral circumflex femoral artery) was longer than parascapular (9.07 ± 1.20 cm, circumflex scapular artery) and lateral arm flap (8.90 ± 1.65 cm, posterior collateral radial artery) (P < 0.001). The thickness of lateral arm flap (6.32 ± 2.33 mm) was lesser than parascapular (8.59 ± 2.93 mm) and anterolateral thigh flap (9.30 ± 3.54 mm) (P < 0.001). The arterial/venous pedicle diameters of lateral arm flap (2.37 ± 0.69 mm / 2.61 ± 0.74 mm) were lesser than parascapular (3.46 ± 0.80 mm / 4.07 ± 0.87 mm) and anterolateral thigh flap (3.26 ± 0.74 mm / 3.87 ± 0.70 mm) (P < 0.001).Conclusions:The vascular pedicle length of anterolateral thigh flap was the longest and that lateral arm flap presented a pedicle with the smallest arterial and venous diameters, in addition to being the thinnest flap. © 2014 Wiley Periodicals, Inc.
