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 compositional types, branches and anastomoses of the superficial palmar arch and the deep palmar arch and to provide anatomical basis for clinical hand surgery. Methods: In 78 cases of cast specimens, we observed the composition, branching and anastomosis of the superficial palmar arch and the palmar deep arch. Results: (1) The superficial arch was divided into 5 types: Ⅰ. The ulnar artery type consisted of the terminal branch of the ulnar artery. The branch directly reached the index finger and thumb without the anastomosis of branches of other arteries, accounting for 19.2% (15 cases). Ⅱ. The radial ulnar artery was composed of radial artery branch and ulnar artery, accounting for 51.3% (40 cases). Ⅲ. The ulnar artery of the ulnar artery was composed of the terminal branch of the ulnar artery and the deep palmplar arch, accounting for 15.4% (12 cases). Ⅳ. The radial midline arteries are composed of the radial artery, the middle artery and the ulnar artery, accounting for 10.3% (8 cases). Ⅴ. There is no arched arch in the non-arch type. The thumb of the superficial branch of the palm of the radial artery, the semilunar of the index finger and middle finger, the middle finger of the ulnar artery and the middle finger of the ulnar artery, 3.8% (3 cases). ⑵ palm deep arch sub-type 2: I. complete palm deep arch by the radial artery and the ulnar ulnar artery or other branches, accounting for 93.6% (73 cases). Ⅱ. Incomplete palmar arch is the terminal branch of the radial artery does not match with other branches, accounting for 6.4% (5 cases). Palm shallow bow, palm deep bow coincide with each other and issue many branches. Conclusion: There are many branches of arched palms and deep palms of the palms, which are rich in anastomosis and large variations. Clinical knowledge should be mastered.
