This article describes a complex variation in the pattern of blood supply to palm of hand encountered during routine dissection. in the present case : there was no communication between superficial palmar branches of the radial and ulnar arteries (incomplete superficial palmar arch [SPA]; the superficial palmar branch of radial artery coursed superficial to the thenar muscles supplying two common palmar digital arteries for adjacent sides of thumb and index finger ( thereby replacing the conventional arteria radialis indices; the branch supplying the lateral side of thumb was seen arising from the deep branch of radial artery; the superficial palmar branch of ulnar artery supplied a branch to medial side of little finger and two common palmar digital arteries for the adjacent sides for the adjacent sides of little and ring finger and ring and middle finger respectively. SPA has received substantial attention in the recent times as it is the major source of vascular supply of the hand, one of the most important tools of evolutionary advancements in humans. Familiarity regarding the variations in the vascular patterns resulting from a number of developmental errors remains the crucial issue for personnel engaged in reconstructive hand surgeries where these varied patterns act as pivotal points around which successful accomplishment of various advanced surgical procedures revolve. With the type of incomplete SPA encountered in the present study, the arterial supply shows increased vulnerability following trauma thereby raising the chances of development of ischemic changes in the distal hand, hence, prior examination of the vascular anatomy of hand in advance of a planned hand surgery is highly recommended.
