Superficial palmar arch completion at the first interdigital cleft: A case report

Knowledge of variations in the formation of superficial palmar arch is beneficial for successful vascular surgery in the hand as well as for plastic surgeons. The authors describe an unusual completion of superficial palmar arch by first dorsal metacarpal branch of radial artery at the first interdigital cleft which was encountered during routine upper limb dissection for undergraduates. The arteria princeps pollicis and arteria radialis indicis also were the branches of first dorsal metacarpal artery at the first interdigital cleft.
