Background: The superficial palmar arch (SPA) is the main source of arterial supply to the palm. It is an arterial arcade formed mainly by the ulnar artery and is completed by the superficial palmar branch of the radial artery or princeps pollicis artery or radialis indicis artery or median artery. The knowledge about the variations in the formation of SPA is important in reconstructive hand surgery and in radial artery grafts.
Objective: The objective of the present study is to identify the arterial patterns in the formation of superficial palmar arch and classify according to its formative tributaries.
Material and Methods: The study conducted on 69 formalin fixed hands at Vydehi Institute of Medical Sciences and Research Centre, Bangalore. The vascular pattern of superficial palmar arch was recorded and classified according to the variations.
Results: It was found that 96% of SPA were complete and 4% incomplete. Based on Coleman and Anson classification, type A arch was identified in 39%, type B in 17%, type C in 9%, type E in 31% and type G in 4%. Another finding was in 35% cases, the ulnar artery was highly tortuous in its course in the palm. A thin collateral or additional branch was found in 31% of the SPA.
Conclusion: These findings on the variations of SPA is essential in microvascular surgery and radial artery harvesting in coronary artery bypass graft procedure.
