The purpose of this study is to measure flap thicknesses of anterolateral thigh (ALT) and medial sural artery perforator (MSAP) flaps in healthy subjects by Doppler ultrasonography and compare the results in relation to sex and body mass index (BMI).
The perforators of ALT and MSAP flaps were marked on 30 healthy subjects. The thickness of skin and subcutaneous tissue was measured in millimeters at the site of the perforator using Doppler ultrasonography.
The mean ± SD age of the participants was 36.4 ± 10.5, the mean ± SD BMI was 25.2 ± 3.9 (19.4-32.5). The mean ± SD flap thickness was 11.55 ± 4.38 mm for ALT and 8.31 ± 3.6 mm mm for MSAP (P < 0.01). Anterolateral thigh flap was significantly thicker than MSAP in both males (9.02 vs 6.11 mm) and females (14.07 vs 10.52 mm) (P < 0.05). The thickness of both MSAP and ALT flap had a positive correlation with BMI. The relationship was stronger for ALT in males (r = 0.66 for ALT, r = 0.59 for MSAP) and for MSAP in females (r = 0.70 for ALT, r = 0.83 for MSAP).
This study confirms that MSAP flap is thinner than ALT and the results correlate with BMI. Therefore, MSAP flap can be considered a good alternative to ALT, to avoid bulk, in reconstruction of shallower soft tissue defects.
本研究的目的是通过多普勒超声测量健康受试者的股前外侧（ALT）皮瓣和腓肠内侧动脉穿支（MSAP）皮瓣的厚度，并比较其与性别和体重指数（BMI）相关的结果。
在30名健康受试者身上标记ALT和MSAP皮瓣的穿支。使用多普勒超声在穿支部位以毫米为单位测量皮肤和皮下组织的厚度。
参与者的平均年龄±标准差为36.4±10.5岁，平均BMI±标准差为25.2±3.9（19.4 - 32.5）。ALT皮瓣的平均厚度±标准差为11.55±4.38毫米，MSAP皮瓣为8.31±3.6毫米（P < 0.01）。股前外侧皮瓣在男性（9.02对6.11毫米）和女性（14.07对10.52毫米）中均明显厚于MSAP皮瓣（P < 0.05）。MSAP和ALT皮瓣的厚度均与BMI呈正相关。在男性中，ALT的相关性更强（ALT的r = 0.66，MSAP的r = 0.59）；在女性中，MSAP的相关性更强（ALT的r = 0.70，MSAP的r = 0.83）。
本研究证实MSAP皮瓣比ALT皮瓣薄，且结果与BMI相关。因此，在修复较浅的软组织缺损时，为避免臃肿，MSAP皮瓣可被视为ALT皮瓣的良好替代方案。
