Variations in the origin and distribution of Berrettini anastomosis between the digital branches of the ulnar and median nerves exist and are well described in the literature. During regular dissections by medical students, we encountered a rare variation in the left hand of an approximately 50-year-old male cadaver. Berrettini anastomosis connecting the third common palmar digital branch of the median nerve with the fourth common palmar and proper palmar digital branches of the ulnar nerve presented a plexiform nature. This communicating branch and the third common palmar digital branch of the median nerve were perforated by the superficial palmar arch. Further, the superficial palmar arch was incomplete, and it was solely formed by the superficial branch of the ulnar artery. The unusual relationship of Berrettini anastomosis with the superficial palmar arch is very rare, and knowledge about such a variation is important when performing carpal tunnel release, flexor tendon surgery, and Dupuytren's fasciectomy and when dealing with arterial repairs and vascular graft applications in the hand.
尺神经和正中神经指支之间的贝雷蒂尼吻合的起源和分布存在变异，且文献中有详细描述。在医学生进行常规解剖时，我们在一名约50岁男性尸体的左手中遇到了一种罕见变异。连接正中神经第三掌侧总指支与尺神经第四掌侧总指支和掌侧固有指支的贝雷蒂尼吻合呈丛状。该交通支和正中神经第三掌侧总指支被掌浅弓穿经。此外，掌浅弓不完整，仅由尺动脉浅支形成。贝雷蒂尼吻合与掌浅弓的这种异常关系非常罕见，了解这种变异在进行腕管松解术、屈肌腱手术、杜普伊特伦挛缩筋膜切除术以及手部动脉修复和血管移植应用时很重要。
