Variation of bilateral superficial palmar arch – A case report with its clinical significance
Journal Title: Medpulse International Journal of Anatomy - Year 2017, Vol 4, Issue 2
Abstract
The anastomoses between radial and ulnar arteries in the palm play a significant role in diseases of the palm through collateral circulation. During routine dissection of the upper limb of a 45-year-old male cadaver, we observed the bilateral incomplete superficial palmar arch (SPA), where both the superficial branches of radial and ulnar artery were present but completely fails to join with each other to form a complete SPA. In right hand, the superficial palmar branch of the radial artery entered the hand above the thenar muscles and provided palmar digital branches to the radial side of the index finger and the ulnar side of the thumb, without any contribution to the SPA. The superficial branch of the ulnar artery gave origin to three common palmar digital arteries to supply the contiguous sides of the index, middle, ring and little fingers. In left hand, both the arteries did not give any branches and ends in the straight course without anastomosis.
