在手术显微镜下解剖30侧成年尸体。发现侧胸区有稳定的轴型皮血管源。在其前部的胸前外侧区,有较恒定的副胸外测血管;在其后部的背阔——胸大肌区有胸外侧动脉和肩胛下—胸背动脉的皮动脉,以及腋动脉的直接皮动脉,它们在该区的分布,可一支为主、另一支为辅,或仅由一支分布。无论哪一种类型都有可供显微外科吻合用的血管蒂。测量了血管管径和可供游离皮瓣作为血管蒂的血管长度。对侧胸区皮血管的分布提出了整体概念,可作游离皮瓣设计的参考。 Anatomy of 30 adult cadavers under a surgical microscope. Found that the lateral chest area has a stable axial skin vascular source. In front of the anteroposterior area of ​​the chest, there is a more constant sub-thoracic blood vessels; in the back of the broad-pectoralis major area of ​​the thoracic artery and subscapular - thoracic artery arteries, and axils The arterial direct skin arteries, their distribution in the area, can be one of the main, the other is supplemented, or only by a distribution. No matter what type of vascular pedicle for microsurgical anastomosis. The vessel diameter and the length of blood vessels available for free flaps as the vessel pediclement were measured. Contralateral thoracic vascular distribution of the proposed the overall concept of the skin flap can be used as a reference design.
