During routine dissection for the undergraduate first MBBS students on the right upper limb of a 70 years old donated embalmed male cadaver in the Department of Anatomy, K.J. Somaiya Medical College, Sion, Mumbai, India, we observed a variant complete superficial palmar arch. The superficial palmar arch was formed by the ulnar artery on medial side and completed by the median artery on the lateral side. The photographs of the variant complete superficial palmar arch were taken for proper documentation and ready reference. There was no associated neuromuscular variations in the same specimen. The formation of the deep palmar arch was normal. The variation was unilateral and the arterial pattern of the left upper limb of the same cadaver was normal. The knowledge of variation in the persistence of median artery helps in planning and performance of surgical procedures in the forearm. The median artery is the only arterial supply to the median nerve. Damage to this artery therefore has clinical significance. Association of a persistent median artery with the median nerve should be considered in the evaluation of all patients with carpal tunnel syndrome. The variations of the vascular pattern of the hand gained more importance in microsurgical techniques, reconstructive hand surgeries, preoperative screening of radial artery harvesting for myocardial revascularization and also in arterial interventions that include radial artery cannulation and radial artery forearm flap.
