这项研究是为了确定利用传入动静脉瘘的组织移植的存活机制。这项研究是使用兔耳室方法进行的。实验一(n=34)用兔耳制作双引流(n=28)或单引流(n=6)的中央动静脉瘘皮瓣，实验二(n=6)制作中心动静脉瘘单次引流的皮瓣。在第一次和第二次实验中，观察了毛细血管和小动脉的血流情况。这一发现被解释为有传入动静脉瘘的皮瓣是通过毛细血管循环进行营养的。似乎血液流动可以绕过正常的静脉瓣膜，进入耳朵的远端。
This study was conducted to determine the survival mechanism of tissue transfers which make use of an afferent arteriovenous fistula. The study was carried out using a rabbit ear chamber method. In the first experiment (n = 34), the rabbit ear was used to create a flap with a central afferent arteriovenous fistula with either dual (n = 28) or single (n = 6) drainage.In the second experiment (n = 6), a flap with a central arteriovenous fistula with single drainage was created as above. The central vein was then ligated in the flap to investigate the influence of the competent venous valve in the central vein.In both the first and second experiments, blood flow was noted in the capillaries and arterioles. This finding was interpreted as meaning that a flap with an afferent arteriovenous fistula is nourished through capillary circulation. It appears that the blood flow can circumvent the competent venous valve to perfuse the distal part of the ear.
