ABSTRACT

SUMMARY:

The axillary artery is a continuation of the subclavian artery and transitions into the brachial artery. Variations in the axillary artery are not uncommon. During the upper-limb dissection of a 95-year-old Korean female cadaver, assorted anatomical variations of the axillary artery branches were identified. On the right side, no branches emerged from the first part of the axillary artery. The thoracoacromial artery (excluding the pectoral branch) and the common subscapular trunk arose from the second part, with the common subscapular trunk giving origins to the pectoral branch, lateral thoracic artery, and subscapular artery. The subscapular artery is divided into the thoracodorsal artery, circumflex scapular artery, and accessory posterior circumflex humeral artery. Additionally, the superior thoracic artery arose from the lateral thoracic artery. The third part of the axillary artery gave rise to the anterior and posterior circumflex humeral arteries, accessory acromial branch, and accessory thoracodorsal artery. On the left side, the thoracoacromial artery (excluding the pectoral branch) and the superior thoracic artery arose from the first part. The common subscapular trunk arose from the second part, which included the pectoral branch, lateral thoracic artery, and subscapular artery. The subscapular artery is divided into the thoracodorsal artery, circumflex scapular artery, accessory posterior circumflex humeral artery, and accessory lateral thoracic artery. The third part gave rise to the anterior and posterior circumflex humeral arteries and the accessory acromial branch. This study presents variations of the axillary artery, emphasizing their rarity, considering their embryologic basis, and highlighting their importance not only for educational purposes but also surgical and radiological applications.
RESUMEN
La arteria axilar es una continuación de la arteria subclavia y luego esta continua como arteria braquial. Las variaciones en la arteria axilar no son infrecuentes. Durante la disección de los miembros superiores de un cadáver de una mujer coreana de 95 años, se identificaron diversas variaciones anatómicas de las ramas de la arteria axilar. En el lado derecho no se originaban ramas de la primera parte de la arteria axilar. La arteria toracoacromial (excluyendo la rama pectoral) y el tronco subescapular común surgieron de la segunda parte, y el tronco subescapular común dio origen a la rama pectoral, la arteria torácica lateral y la arteria subescapular. La arteria subescapular se dividía en arteria toracodorsal, arteria circunfleja escapular y arteria humeral circunfleja posterior accesoria. Además, la arteria torácica superior se originaba de la arteria torácica lateral. La tercera parte de la arteria axilar dio origen a las arterias circunflejas humerales anterior y posterior, la rama acromial accesoria y la arteria toracodorsal accesoria. En el lado izquierdo, de la primera parte surgían la arteria toracoacromial (excluyendo la rama pectoral) y la arteria torácica superior. De la segunda parte se originaba el tronco subescapular común, que incluía la rama pectoral, la arteria torácica lateral y la arteria subescapular. La arteria subescapular se dividía en arteria toracodorsal, arteria circunfleja escapular, arteria circunfleja humeral posterior accesoria y arteria torácica lateral accesoria. La tercera parte daba origen a las arterias circunflejas humerales anterior y posterior y a la rama acromial accesoria. Este estudio presenta variaciones de la arteria axilar, enfatizando su rareza, considerando su base embriológica y destacando su importancia no sólo para fines educativos sino también para aplicaciones quirúrgicas y radiológicas.
