STUDY ON VARIATIONS IN THE BRANCHING PATTERN OF ARCH OF AORTA
Journal Title: International Journal of Pharmacy and Pharmaceutical Sciences - Year 2015, Vol 7, Issue 9
Abstract
The most common branching pattern of the aortic arch in humans comprises of three great vessels, during the routine dissection for 1st MBBS we encountered variations in the branches of arch of aorta, so the study was conducted to know the percentage and common type of variations. The study was performed on thirty hearts, among the 30 hearts 28 were adult formalin preserved cadavers and two were pre-dissected separate hearts with the aortic arches en-bloc. The sex and age of the cadavers were not assessed in the study. A study was conducted for a period of two years. The purpose of the study was to measure the percent of variation in the branching pattern of an arch of aorta. The most common branching pattern of the aortic arch in humans comprises of three great vessels; first, the brachiocephalic trunk, then the left common carotid artery and finally the subclavian artery. In the present study the most common aortic arch branching pattern was found in 86.67%, additional artery that is four branches were observed in 10% of the cases and two arteries from the arch of aorta, were noted in 3.33% of the case studied. Different branching patterns of the arch of aorta observed in this study and these can assist surgeons in performing safe and effective surgeries in the superior mediastinum.Â
