摘要目的 探讨应用桡动脉掌浅支Flow-through 皮瓣桥接修复合并血管及软组织缺损的断指的手术方法及治疗效果.方法 2013年2月至2018年3月,对9例手指离断合并血管及软组织缺损的患者,采用桡动脉掌浅支Flow-through皮瓣进行桥接完成再植.皮瓣设计在腕横纹部近端, 切取面积为3.0 cm×1.5 cm~4.0 cm×2.2 cm,供区均直接缝合.皮瓣内桡动脉掌浅支桥接指掌侧固有动脉,皮下静脉桥接手指创面远、近端静脉;对指掌侧固有神经缺损者,采用皮瓣携带正中神经掌皮支桥接修复.术后定期随访,随访方法包括手指外观、感觉及手指关节功能.结果 术后9例皮瓣及断指全部成活,并获得7~33个月随访.皮瓣质地优良,外形满意,痛觉、温觉、触觉均有较好恢复,两点辨别觉达8~11 mm;再植指体外形及功能均恢复良好.供区仅留下线形手术瘢痕,无功能影响.按照Michigan手部功能问卷评定标准,9例患者对手部整体外观及功能非常满意.手指活动度按照TAM评定标准,优5例,良4例.结论 桡动脉掌浅支Flow-through皮瓣具有解剖恒定、切取方便、供区创伤小的优点;而且血管管径与手指血管匹配,便于吻合,是移植桥接合并血管及软组织缺损的断指的理想方法之一.

abstractsTo evaluate the surgical technique and clinical effect of applying Flow-through flap pedicled with superficial palmar branch of radial artery for bridging finger replantation complex defect of soft tissue and vessel. Methods From February, 2013 to March, 2018, 9 cases of severed fingers composited defect of soft tissue and vessel were treated with Flow-through flap pedicled with superficial palmar branch of radial artery.The flap was designed from the proximal end of rasceta and the donor sites were sutured directly. The size of flaps was 3.0 cm ×1.5 cm-4.0 cm×2.2 cm. The superficial branch of the radial artery in the flap was used to bridge the finger artery. And the vein of proximal and distal ends in the finger was bridged by the subcutaneous vein. The proper palmar digi-tal nerve defect was bridged by palm skin graft of median nerve. The appearance, feeling and joint function of fingers was followed-up regularly after operation. Results All transfering flaps survived and all cases were followed-up for 7 to 33 months. The donor sites got primary healing with straight scars. The appearance and texture of the flaps were satisfactory. Two-point discrimination ranged from 8 to 11 mm. The pain sensation, warmth sensation and touch sen-sation of the flaps got better. And the appearance and functions of severed fingers recovered well. Conclusion The Flow-through flap pedicled with superficial palmar branch of radial artery is easy to harvest and anastomose, which is masked and a small incision for the donor site. It is an ideal method for bridging severed fingers and repairing of fin-ger wound.
