【摘要】：目的为临床设计切取腕横纹皮瓣提供解剖学基础。方法选取6只新鲜手标本进行红色乳胶灌注,解剖观察桡动脉掌浅支的走行及皮支分布规律和特点。结果桡动脉掌浅支于桡骨茎突掌尺侧自桡动脉发出,起始处直径(1.26±0.36)mm,向鱼际肌走行。桡动脉掌浅支于舟骨结节近侧中间腕横纹处发出皮支,皮支发出处直径(0.23±0.06)mm,供养腕横纹皮肤。结论以桡动脉掌浅支腕横纹皮支供血,以腕横纹皮肤为供区切取游离皮瓣或带蒂转移可以修复手部皮肤软组织缺损,该术式具有血供可靠、不牺牲主干血管,切取安全等优点。
[Abstract]:Objective to provide anatomic basis for the clinical design of the transverse carpal flap. Methods six fresh hand specimens were perfused with red latex. The pattern and distribution of the superficial metacarpal branch of radial artery were observed. Results the superficial palmar branch of radial artery originated from the ulnar side of the metacarpal artery of the styloid process of the radius. The diameter of the starting point is 1.26 卤0.36 mm, and it runs towards the thenar muscle. The superficial palmar branch of the radial artery sends out a cutaneous branch at the middle transverse stripe of the wrist near the scaphoid tubercle, and the diameter of the cutaneous branch of the cutaneous branch is 0.23 卤0.06 mm to support the skin of the transverse carpal stripe. Conclusion the superficial branch of the radial artery provides blood supply for the cutaneous branch of the transverse stripe carpal of the superficial palmar branch of the radial artery. The free skin flap or pedicle transfer can be used to repair the soft tissue defect of the hand. The operation has the advantages of reliable blood supply, no sacrificing of the main blood vessels, and the removal of safety.
