Conclusion 　It is not important to know w hether radial or ulnar artery ha s the dominance in supply ing bloo d to the hands.T he key point is whether r adial or ulnar artery can supply sufficient blood to the hands solely . 【Key words】　　Radial artery;Ulnar artery;Bloo d supply of hands [Jiangsu Med J, March 2006, 32(3):223-224.] 　　, (radial artery , RA )、 。 (ulnar artery , UA ), , 10 min , 、 、,。 , , 2 cm , , , ,; Allen , CDFI , 。、 , 。 ,, ;, 、 , 32 、64 , 17 , , 60 ; 21～51 ; 15 ,24 ～47 , Doppler ;, 。 5 , 。 、 :、 D、 Acuso n-512 ,
