Abstract
Aim: To measure various dimensions of ligamentum arteriosum as well as observe postnatal anatomical changes of ligamentum arteriosum and discuss clinical significance of it.Methods: 35 heart specimens were studied in Department of Anatomy of Akash medical college. Different shapes as well as length and width of ligamentum arteriosum was measured. Ligamentum arteriosum, aortic arch and pulmonary trunk were incised and looked for ridges, dimples, calcification and atherosclerotic patch. Histological examination of ligamentum arteriosum was also studied in 2 specimens.
Results: cylindrical shape was observed in all specimens of ligamentum arteriosum. The average length and width was measured as 12.02mm and 3.73mm respectively. Ligamentum arteriosum was found to be obliterated in 7 specimens whereas calcified in 3 specimens. Dimples and atherosclerotic patch was observed in luminal surface of pulmonary trunk and aorta respectively. Ligamentum arteriosum was presented as muscular artery in microscopic examination.
Conclusion: ligamentum arteriosum is clinically important structure. Details about its characteristics and clinical co relations may be helpful to the clinicians.
