Objective:To study the types,courses,branches and anastomosis of superficial and deep palmar arches and provide anatomic basis for clinical application of hand surgery.Methods:The forming,branches and anastomosis of superficial and deeo palmar arches were observed and analyzed on 78 casting specimens of hand.Results:⑴ Superficial palmar arch could be divided into five patterns:ulnar artery pattern(Ⅰ),formed by terminal branches of ulnar artery and distributed to index finger and thumb,without any other anastomosis.This pattern was about 19.2%(15 cases);radial ulnar artery pattern(Ⅱ),formed by the branches of radial artery and ulnar artery.This pattern was about 51.3%(40 cases);the pattern of deep palmar arch of ulnar artery(Ⅲ),formed by branches of ulnar artery and deep palmar arch.This pattern was about 15.4%(12 cases);radial median ulnar artery pattern(Ⅳ),formed by radial,median and ulnar arteries.This pattern was about 10.3%(8 cases);.non-arch pattern(Ⅴ),with no superficial palmar arch.This pattern was about 3.8%(3 cases).⑵ Deep palmar arch could be divided into two patterns:complete pattern(Ⅰ),formed by branches of radial and ulnar arteries.This pattern was about 93.6%(73 cases);Incomplete pattern(Ⅱ),formed by branches of radial artery.This pattern was about 6.4%(5 cases).Superficial and deep palmar arches anastomosed with each other and given many branches.Conclusions:Superficial and deep palmar arches branch have extensive anastomosis,which is important anatomic features and should be cautioned during the hand surgery.
