title: A study on axillary artery and its branching pattern among the population of West Bengal, India.
abstract: Variations in the branching pattern of the axillary artery have paramount importance among anatomists, surgeons and radiologists. A study was conducted on this topic in Kolkata, among the people of West Bengal, a state of India. The upper limbs of 70 cadavers were dissected bilaterally at the Department of Anatomy, Calcutta National Medical College, Kolkata, between 2008 and 2011. Among the study population, 52 cadavers (74.3%) were male and the rest were female, with average age 62.01 years (standard deviation = 6.58) and average height 1.59 meter (standard deviation = 0.096) respectively. The mean length of the axillary artery was 10.15 cm (standard deviation = 1.056). The superior thoracic, thoracoacromial and subscapular arteries were found to be constant branches of the axillary artery while the other branches showed considerable variations. Among those constant branches a high, significant correlation was found between the distance of origin of thoracoacromial artery from the outer border of the 1st rib and the length of the axillary artery, for the right and respectively the left upper limb of male cadavers. In females it showed a moderate, albeit significant correlation only. Similarly, the length of the axillary artery established a moderate correlation with the distance of origin of the superior thoracic and of the subscapular arteries on the right side of female cadavers. No other significant correlation was obtained.
