Abstract

In a Greek Caucasian male cadaver, a combination of the following arterial variations were observed: an aberrant right subclavian artery originating as a last branch of the aortic arch and coursed posterior to the esophagus, a right non-recurrent laryngeal nerve, an atypical origin of the left suprascapular artery from the axillary artery, an unusual emersion of the lateral thoracic artery from the subscapular artery and a separate origin of the left thoracodorsal artery from the axillary artery. According to the available literature the corresponding incidences of the referred variants are: 0.7% for the aberrant right subclavian artery, 1.6-3.8% for the origin of the suprascapular artery from the axillary artery, 3% for the origin of the left thoracodorsal artery from the axillary artery and 30% for the origin of the lateral thoracic artery from the subscapular artery. Such unusual coexistence of arterial variations may developmentally be explained and has important clinical significance.
