ABSTRACT:

Background: The functional importance of hand is revealed by its rich vascularity contributed by superficial and deep palmar arches (SPA and DPA). The efficiency of collateral circulation in hand by SPA and DPA is essential in certain peripheral vascular diseases like Raynaud’s disease and in harvesting radial artery for coronary artery bypass graft (CABG). Knowledge of variations in the arterial supply of hand is important while performing microsurgical procedures like arterial repair, vascular graft and flap application.

Objective: To study the morphology of the Superficial Palmar Arch and variation in its formation.

Materials and methods: We have dissected 30 cadaveric hands at Department of Anatomy of Medical College and Hospital, Kolkata.

Result and conclusion: Out of 30 specimens, variations were observed in 14 specimens. Out of 14 specimens in 11 specimens SPA was formed alone by Ulnar Artery, in two specimens SPA was incomplete formed by superficial palmar branches of Ulnar and Radial Artery, in one specimen there was presence of Persistent Median Artery with incomplete SPA. All the variations found were present unilaterally. In rest 16 specimens SPA was complete classical radio-ulnar type.

KEY WORDS: Superficial palmar arch (SPA), Ulnar artery (UA), Radial artery (RA), Persistent Median artery (PMA).
