| Summary: | Anatomical variation of the branching pattern of axillary artery is very common. The knowledge of this variation is often useful during
different surgical and interventional procedures. Variations include typically of Lateral Thoracic Artery (LTA) and Posterior Circumflex
Humeral Artery (PCHA). The present case has been reported to document the variation of LTA and PCHA. The axilla of a 65-yearold embalmed female cadaver was routinely dissected for educational purpose in the Department of Anatomy, AIIMS, New Delhi,
India. Cunnighams Manual of Dissection was followed during the whole dissection procedure. We found that the third part of axillary
artery gave rise to a common trunk which divided into PCHA and LTA. The PCHA curved backwards around the humeral neck and
made anastomosis with the anterior circumflex humeral artery. The LTA supplied serratus anterior and the pectoral muscles and made
anastomosis with intercostal arteries. The axillary nerve accompanied PCHA while the thoracodorsal nerve accompanied LTA. The rare
anatomical variation of the branching pattern of axillary artery is assumed to be helpful in the surgical procedures and various therapeutic
interventions of the upper limb. |
