The aim of this study was to confirm the morphometry of the anterolateral thigh (ALT) pedicle and the location of the perforators in the adult Vietnamese population.
Forty dissections of the thigh were carried out in 20 Vietnamese dedicate cadavers. Including 13 cadavers were fixed by Formalin and 7 cadavers were fixed by fridge. The number, origin, location of the perforators and the diameter of the ALT pedicles were studied and measured.
The length of the thigh was 39.9 ± 2.8 cm. 39/40 cases (97.5%) were a perforator of a 4 cm circle drawn at the midpoint thigh. There were 161 perforators. In 82.7% of perforators were musculocutaneous perforators and 17.3% perforators were septocutaneous perforators. There were 5 types of vascular pedicles. Type 1: the perforators originated from the descending branch were 65%; Type 2: from the oblique branch were 22.5%; Type 3: from the transverse branch were 5%; Type 4: from profunda femoris were 5%; Type5: from femoral artery were 2,5%. The average length of the flap pedicle was 11.6 ± 2.4 cm, the diameter of the artery was 2.51 ± 0.52 mm, the vein was 2.95 ± 0,56 mm and 2.18 ± 0,46.
The ALT flap is a constant vascular supply, a long pedicle with a suitable diameter for anastomoses. The ALT can be harvest widely and reliable with a perforator of a 4 cm circle drawn at the midpoint thigh.
本研究的目的是确定成年越南人群中股前外侧（ALT）蒂的形态测量以及穿支的位置。
对20具越南捐献尸体的大腿进行了40次解剖。其中13具尸体用福尔马林固定，7具尸体用冰箱固定。研究并测量了穿支的数量、起源、位置以及ALT蒂的直径。
大腿长度为39.9±2.8厘米。40例中有39例（97.5%）在大腿中点绘制的4厘米圆圈内有一个穿支。共有161个穿支。82.7%的穿支为肌皮穿支，17.3%为隔皮穿支。有5种类型的血管蒂。1型：穿支起源于降支的占65%；2型：起源于斜支的占22.5%；3型：起源于横支的占5%；4型：起源于股深动脉的占5%；5型：起源于股动脉的占2.5%。皮瓣蒂的平均长度为11.6±2.4厘米，动脉直径为2.51±0.52毫米，静脉直径为2.95±0.56毫米和2.18±0.46毫米。
ALT皮瓣有恒定的血管供应，蒂长且直径适合吻合。在大腿中点绘制的4厘米圆圈内有一个穿支时，ALT可以广泛且可靠地切取。
