Abstract：
Anatomic variations of axillary artery branches are commonly encountered during radiological investigation and surgical operations. Their existence can confuse interpretation of radiological results and lead to undesired complications during surgery. In this report authors describe a rare case of a subscapular arterial trunk that gave origin to thoracodorsal, circumflex scapular, posterior humeral circumflex, and lateral thoracic artery. Such a variation might cause undesired sequelae during trauma management and a variety of common flap harvesting operations including latissimus dorsi, scapular and parascapular flaps. Furthermore it presents embryological interest as it gives insight to embryologic development of axillary area.
摘要：
在放射学研究和外科手术中通常会遇到腋下动脉分支的解剖变化。它们的存在会混淆放射学结果的解释，并导致手术过程中不希望的并发症。在这份报告中，作者描述了一种罕见的肩胛骨下动脉干的病例，旋肩胛骨,肱骨后回旋，和胸外侧动脉.这种变化可能会在创伤处理和包括背阔肌在内的各种常见皮瓣收获手术中引起不希望的后遗症，肩胛骨和副肩胛骨皮瓣。此外，它还具有胚胎学意义，因为它可以洞悉腋窝区的胚胎发育。
