Why is it important?
Introduction: Abnormalities of great vessels of heart, especially arch of aorta, are of embryological interest and have already been described in many text books of anatomy. The embryological development of aortic arch is very complex that finally results in the formation of three branches: 1) brachiocephalic trunk 2) left common carotid artery and 3) left subclavian artery. In the present study we have found a case of abnormal aortic arch giving rise to four branches and also ligamentum arteriosum. We also found three more cases of ligamentum arteriosum. During the foetal life, Ductus arteriosus provides communication between pulmonary and systemic circulations. This normal anatomical structure closes soon after birth and undergoes fibrosis which is termed as ligamentum arteriosum that persists up to 3 months of post natal life. Aims and Objectives: The clinicians and surgeons should be aware of wide range of congenital anomalies of great vessels of heart during the management of such cases. Therefore the present study focuses on reporting of such cases to reduce the risk of iotrogenic injuries. Materials and Methods: We had studied 80 embalmed cadavers for a period of 3 years for the presence of anomalous great vessels of heart. Results: We have found four hearts with anomalous great vessels. One of the hearts had abnormal aortic arch that had given rise to four branches. It also had persistent ligamentum arteriosum. In the other three cases, we found only persistent ligamentum arteriosum. Conclusion: Knowledge of variations in great vessels of heart is important for the practitioners to reduce the disastrous vascular complications.
