解剖了50具成年尸体,对背阔肌皮瓣的形态、大小、血管和神经进行了观察和测量。肩胛下动脉的长度为23.8±1.2mm,外径为3.7±0.2mm。胸背动脉的长度为92.2±1.9mm,外径为2.3±0.1mm。胸背神经的干长为75.9±1.9mm,外径为2.0±0.1mm。主要神经血管门约位于腋后襞下方10cm,背阔肌前缘后方2cm,相当于肩胛骨下角平面处。整个背阔肌表面的皮肤,除了肩胛骨下角平面稍上方的皮肤外,均可作为肌皮瓣提取。对背阔肌皮瓣、肌骨皮瓣和反转的岛状感觉肌皮瓣的临床应用作了讨论。
Fifty adult cadavers were dissected, and morphological, size, vascular and neural findings of latissimus dorsi flap were observed and measured. The subscapular artery has a length of 23.8 ± 1.2 mm and an external diameter of 3.7 ± 0.2 mm. Thoracodorsal artery length of 92.2 ± 1.9mm, an outer diameter of 2.3 ± 0.1mm. Thoracodorsal nerve dry length of 75.9 ± 1.9mm, an outer diameter of 2.0 ± 0.1mm. The main neurovascular door about 10cm below the axillae, behind the latissimus dorsi margin 2cm, equivalent to the lower blade angle plane. The entire surface of the latissimus dorsi skin, in addition to a little above the plane of the lower part of the shoulder blade skin, can be extracted as myocutaneous flap. The clinical application of latissimus dorsi flap, musculocutaneous flap and inverted island sensory myocutaneous flap were discussed.
