The superficial palmar arch incredibly provides hand with the blood supply, which is normally formed by the ulnar artery and superficial palmar branch of the radial artery. In the current case, the unilateral absence of superficial palmar arch with the rare presence of the median artery was reported, which was noticed in the right hand of a male cadaver during a routine educational dissection. The awareness of particular variations in hand blood supply during hand operations leads in preventing surgical mistakes.</span></span></p> Hand, Persistence Median Artery (PMA), Superficial Palmar Arch (SPA) 57 61 http://journal.zums.ac.ir/browse.php?a_code=A-10-5099-1&slc_lang=en&sid=1 Behnaz Valipour behnaz.valipour1@gmail.com 5200319475328460052940 5200319475328460052940 Yes Dept. of Anatomical Sciences, Faculty of Medicine, Tabriz University of Medical Sciences, Tabriz, Iran Hamid Tayefi Nasrabadi Tayefih@yahoo.com 5200319475328460052941 5200319475328460052941 No Dept. of Anatomical Sciences, Faculty of Medicine, Tabriz University of Medical Sciences, Tabriz, Iran Kobra Velaei kobravelaei@gmail.com 5200319475328460052942 5200319475328460052942 No Dept. of Anatomical Sciences, Faculty of Medicine, Tabriz University of Medical Sciences, Tabriz, Iran Ahad Ferdowsi Kh a.ferdosi.kh@gmail.com 5200319475328460052943 5200319475328460052943 No Dept. of Anatomical Sciences, Faculty of Medicine, Tabriz University of Medical Sciences, Tabriz, Iran Khadijeh Dizaji Asl Kh.asli2013@gmail.com 5200319475328460052944 5200319475328460052944 No Dept. of Anatomical Sciences, Faculty of Medicine, Tabriz University of Medical Sciences, Tabriz, Iran
