Anomalous arterial pattern are having significant importance for anatomist, vascular reconstruction surgeons and radiologists. The present study was conducted on 22 formalin fixed cadavers. Out of which 4 cadavers showed variation in the course and branching pattern of superior thoracic artery. In 2 male cadavers, superior thoracic artery showed unusual course and other 2 cadavers showed variations in the branching pattern of lateral thoracic and subscapular arteries. Knowledge of these arterial patterns is useful in determining pathology of arteries, their proper surgical procedures and proper diagnostic interpretation.
