A case Report on Variant Blood Supply of Hand and its Clinical Significance

Dr. Sharadkumar Pralhad Sawant

Abstract :

During routine dissection for the undergraduate first MBBS students on the left 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 superficial palmar arch. The superficial palmar arch was formed by the ulnar artery on medial side and was completed by the median artery on the lateral side. The photographs of the variant left superficial palmar arch were taken for proper documentation and ready reference. There was no associated neuromuscular variations. The formation of the deep palmar arch was normal. The variation was unilateral and the arterial pattern of the right upper limb of the same cadaver was normal. The knowledge of variations of vascular pattern of 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.
