在局部血管不足的受体部位附近建立临时动静脉分流（TAVS）可能有助于随后的游离皮瓣血运重建。在9名患者中，在转移游离皮瓣之前构建了TAVS。适应症是缺乏血管或受体血管不足。9例患者中有8例成功建立了分流。在1例患者中，由于感染引起的血栓形成，需要重新建立分流。另一例患者的分流管血栓形成，无法进行进一步的微血管手术。TAVS的建立增加了游离皮瓣转移更广泛应用的可能性。如果建立分流证明是徒劳的，供体皮瓣仍然可以挽救进一步的应用。在初次建立TAVS后，分期转移游离皮瓣可为皮瓣提供最佳的血管化改变，并降低血栓形成的风险。
The establishment of a temporary arteriovenous shunt (TAVS) near a recipient site with inadequate local vessels may facilitate the subsequent re-vascularization of a free flap. In nine patients a TAVS was constructed prior to the transfer of free flaps. The indication was either the absence of vessels or inadequate recipient vessels. In eight of the nine patients the establishment of the shunt proved successful. In one patient a re-creation of the shunt was necessary owing to thrombosis caused by infection. In another patient the shunt thrombosed and no further microvascular surgery was possible. The construction of a TAVS increases the possibility of more extensive application of free flap transfer. Should the creation of the shunt prove futile, the donor flap may still be salvaged for further application. A staged transfer of a free flap after the primary establishment of a TAVS gives the best changes for adequate vascularization of the flap and reduces the risk of thrombosis.
