腋动脉第三段分支之一肩胛下动脉,在距起点4厘米处分为胸背动脉及旋肩胛动脉。后者走行到肩胛骨外侧缘时,再分为肩胛和肩胛旁两支皮肤终末支。根据此二支分布可形成肩胛区皮瓣与肩胛旁皮瓣。分别或同时应用此二瓣修复颌面部缺损,效果良好。肩胛下动脉及其伴随静脉恒定,以此作蒂,蒂长可达7～8厘米,管径在1.5毫米以上,有一定量的皮下或皮下与肌肉组织填充缺损。供皮区无功能及外观的影响。供皮区创面可直接缝合。其缺点是血管位置较深操作稍难,体位不同难以同时进行手术而时间加长。血管吻合方法采用国产73—2型小血管吻合器,方法简便,吻合快,效果好。
One of the third branch of axillary artery subscapular artery, at a distance of 4 cm at the beginning into the thoracodorsal artery and spinous artery. The latter walked to the lateral edge of the scapula, then divided into scapular and scapular two skin end branches. According to the distribution of these two branches can form scapular flap and scapular flaps. Using these two valves separately or simultaneously to repair maxillofacial defects, the effect is good. Subscapular artery and its accompanying venous constant, as pedicle, pedicle length of up to 7 to 8 cm, diameter of 1.5 mm or more, there is a certain amount of subcutaneous or subcutaneous and muscle tissue filling defects. Donor area without function and appearance. Donor area wounds can be directly sutured. The disadvantage is that the vascular position is slightly harder to operate at different positions difficult to operate at the same time and longer. Vascular anastomosis method using domestic 73-2 small vessel stapler, the method is simple, fast anastomosis, the effect is good.
