Abstract

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.
