To determine systematically the pattern of the cutaneous perforator of the lateral circumflex femoral artery (LCFA) in anterolateral thigh perforator (ALT) flap.
Sixty dissections of the LCFA were carried out in 30 preserved cadavers. The number; type, origin, and location of the cutaneous perforators of the LCFA were studied and measured.
There were 169 perforators. In 79.3%, the perforators originated from the descending branch, 18.3% from the transverse branch. The perforator of the medial descending and the ascending branch were found in 1.8% and 0.6%, respectively. The most cutaneous perforators were concentrated in the middle third (14 to 28 cm from the ASIS) of the anterolateral thigh region.
The perforator of the descending branch, which was located ranging from 21 to 35 cm, was appropriate for flap designing to avoid the perforator of the transverse branch, which was difficult to harvest.
系统确定旋股外侧动脉（LCFA）在股前外侧穿支皮瓣（ALT）中的皮穿支分布模式。
对30具防腐尸体的LCFA进行60次解剖。研究并测量LCFA皮穿支的数量、类型、起源和位置。
共有169个穿支。79.3%的穿支起源于降支，18.3%起源于横支。内侧降支和升支的穿支分别占1.8%和0.6%。大多数皮穿支集中在大腿前外侧区域的中1/3（距髂前上棘14至28厘米）。
位于21至35厘米范围内的降支穿支适合皮瓣设计，可避开难以获取的横支穿支。
