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.
本研究旨在确定利用传入动静脉瘘的组织移植的存活机制。该研究采用兔耳腔法进行。在第一个实验（n = 34）中，兔耳用于制作带有中央传入动静脉瘘的皮瓣，其引流方式为双支（n = 28）或单支（n = 6）。在第二个实验（n = 6）中，如上所述制作带有中央动静脉瘘且单支引流的皮瓣。然后结扎皮瓣中的中央静脉，以研究中央静脉中健全静脉瓣的影响。在第一个和第二个实验中，均观察到毛细血管和小动脉中有血流。这一发现被解释为意味着带有传入动静脉瘘的皮瓣通过毛细血管循环获得营养。血流似乎可以绕过健全的静脉瓣，灌注耳部远端。
