Abstract For reconstruction of volar defects, an arterialised flow-through venous flap (A-A flap) can be used to restore the soft tissues and the digital artery at the same time. However, there have been reports that the circulation of this flap is inadequate. This study used a venous flap with only one venous anastomosis for the outflow of an A-A flap (A-A-V flap) to solve this problem. Six patients with defects of the finger soft tissues and digital artery after severe finger injuries were performed. The venous flap with a Y-shaped vein was harvested. The digital artery was reconstructed, after which the other proximal vein of this flap was anastomosed to the dorsal subcutaneous vein. The flap survived in all patients and histological examination of flap tissue showed a nearly normal architecture. This study describes the good results obtained with an A-A-V flap, and discusses the utility of our flap in comparison with previously reported venous flaps.
摘要 对于手掌缺损的重建，可使用动脉化穿支静脉皮瓣（A-A皮瓣）同时修复软组织和指动脉。然而，有报道称该皮瓣的血供不足。本研究采用一种仅通过单一静脉吻合口进行A-A皮瓣流出道引流的静脉皮瓣（A-A-V皮瓣）来解决这一问题。对6例严重手指损伤后手指软组织和指动脉缺损的患者进行了手术。切取带有Y形静脉的静脉皮瓣。重建指动脉，然后将该皮瓣的另一近端静脉与手背皮下静脉吻合。所有患者的皮瓣均存活，皮瓣组织的组织学检查显示结构近乎正常。本研究描述了A-A-V皮瓣取得的良好效果，并与先前报道的静脉皮瓣相比，讨论了我们这种皮瓣的实用性。
