Abstract

Introduction: The superficial palmar arch (SPA)is a major source of blood supply to much of the hand and is conventionally formed by the anastomosis of the ulnar artery with the superficial branch of the radial artery. The SPA has been classified into complete or incomplete based on the presence or absence of anastomosis between the arteries contributing to the formation of this palmar arch. Case report: Reported here is a unilateral presentation of incomplete superficial palmar arch. The ulnar artery (UA)gave off one proper palmar digital artery, which supplied the ulnar side of the little finger, and two common palmar digital arteries, which supplied the little, ring, and the middle finger. The superficial palmar branch of the radial artery gave off a proper palmar digital artery to the thumb, and two common palmar digital arteries, which supplied the thumb, index, and middle fingers. Apart from the presence of the incomplete SPA, persistent median arteries were also observed bilaterally in this cadaver. Discussion: The prevalence of incomplete SPA has been reported to vary between 3.6–54.76%. To the best of our knowledge, this is the first case report describing an incomplete palmar arch and bilateral persistent median artery in a cadaver. Conclusion: Patients should be screened for the presence of complete or incomplete SPA before harvesting the radial artery either for myocardial revascularization or for radial artery forearm flap to prevent ischemic complications in the hand.
