Variations in formation of the superficial palmar arch are common. A classic superficial palmar arch is defined as direct continuity between the superficial branch of the ulnar artery and superficial palmar branch of the radial artery. During routine dissection classes to undergraduate medical students we have observed formation of superficial palmar arch solely by superficial branch of ulnar artery without any contribution from the radial artery or median artery. Knowledge of the anatomical variations of the arterial pattern of the hand is crucial for safe and successful hand surgery.
掌浅弓形成的变异很常见。典型的掌浅弓被定义为尺动脉浅支与桡动脉掌浅支直接延续。在给本科医学生上常规解剖课时，我们观察到掌浅弓仅由尺动脉浅支形成，桡动脉或正中动脉没有任何贡献。了解手部动脉模式的解剖变异对于安全、成功地进行手部手术至关重要。
