The purpose of this study was to investigate the viability of two types of unconventional flaps: 1) the arterialized venous perfusion (AVP) flap; and 2) the prefabricated flap. Four experimental groups were studied: an AVP flap group with assessment of the viability of single and paired flaps nourished by the same vascular pedicle; a prefabricated flap group with the abdominal flap pedicled on the epigastric artery and vein; a prefabricated flap group in which the flap was supplied by an arterialized vein graft (A-V shunt), and paired flaps of different designs, but based on the same vascular pedicle, were investigated; and a free composite graft group. Survival of the skin flaps exceeded 92 percent in each group, except in the free composite group which showed complete necrosis. Results of the study validated that flap viability was independent of flap size (large or small), type (AVP flap or prefabricated flap), and the number of flaps on each vascular pedicle (single or paired).
1）动脉化静脉灌注（AVP）皮瓣；2）预制皮瓣。研究了四个实验组：一个AVP皮瓣组，评估由同一血管蒂滋养的单蒂和双蒂皮瓣的可行性；一个预制皮瓣组，其腹部皮瓣以腹壁上动静脉为蒂；一个预制皮瓣组，其中皮瓣由动脉化静脉移植（动静脉分流）供血，并研究了基于同一血管蒂的不同设计的双蒂皮瓣；以及一个游离复合移植组。除游离复合组皮瓣完全坏死外，每组皮瓣存活率均超过92%。研究结果证实，皮瓣的可行性与皮瓣大小（大或小）、类型（AVP皮瓣或预制皮瓣）以及每个血管蒂上的皮瓣数量（单蒂或双蒂）无关。
