摘　　要：目的:研究掌浅弓、掌深弓的组成类型、分支及吻合,为临床手外科提供解剖学基础。方法:在78例手的铸型标本上观察掌浅弓、掌深弓的组成、分支及吻合。结果:⑴掌浅弓分5型:Ⅰ.尺动脉型由尺动脉的终支构成,其分支直接到示指、拇指,不与其它动脉的分支吻合,占19.2%(15例)。Ⅱ.桡尺动脉型由桡动脉分支与尺动脉构成,占51.3%(40例)。Ⅲ.尺动脉掌深弓型由尺动脉的终支和掌深弓构成,占15.4%(12例)。Ⅳ.桡正中尺动脉型由桡动脉、正中动脉和尺动脉构成,占10.3%(8例)。Ⅴ.无弓型没有掌浅弓,桡动脉掌浅支分支营养拇指、示指及中指桡侧半,尺动脉分支营养中指尺侧半、无名指、小指,占3.8%(3例)。⑵掌深弓分2型:Ⅰ.完全型掌深弓由桡动脉的终支与尺动脉或其它分支构成,占93.6%(73例)。Ⅱ.非完全型掌深弓是桡动脉的终支不与其它分支吻合,占6.4%(5例)。掌浅弓、掌深弓互相吻合且发出许多分支。结论:掌浅弓、掌深弓分支众多,吻合丰富,变异大,临床手术时应熟练掌握相关知识。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： （1） 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 pattem（Ⅱ）, formed by the branches of radial artery and ulnar artery. This pattern was about 51.3% （40 cases）; the pattem 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）. （2） Deep palmar arch could be divided into two patterns： complete pattern （Ⅰ）, formed by branches of radial and ulnar arteries. This pattem 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.
