This study aims to compare the major anatomical aspects among anterolateral thigh, parascapular and lateral arm flaps.


Sixty flaps were dissected in 20 human cadavers, comparing their vascular pedicle length, flap thickness and arterial/venous pedicle diameters.


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).


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.
