The authors have studied the effects of various circulatory settings on flap survival. The dog model was used to study the survival of venous flaps without arterial inflow both as island and free flaps. Venous flaps were compared with arterial flaps without venous outflow and standard island flaps with arterial inflow and venous outflow. Attempts were made to study their vascular morphology and blood gas changes. The venous flaps without arterial inflow survived with normal hair growth and wound healing, as did the standard island flaps. These observations suggest that capillary diffusion can occur without the continuous flow of blood through a capillary. Several possible mechanisms to explain survival of the venous flaps without arterial inflow were discussed. These observations could be important in providing an animal model to study microcirculation and a possible new area for microsurgical transfer of a skin flap.
作者研究了各种循环条件对皮瓣存活的影响。采用犬模型研究了无动脉血流的静脉皮瓣作为岛状皮瓣和游离皮瓣的存活情况。将静脉皮瓣与无静脉流出的动脉皮瓣以及有动脉流入和静脉流出的标准岛状皮瓣进行了比较。试图研究它们的血管形态和血气变化。无动脉血流的静脉皮瓣与标准岛状皮瓣一样，毛发正常生长且伤口愈合良好。这些观察结果表明，即使没有血液持续流经毛细血管，毛细血管扩散也可能发生。讨论了几种解释无动脉血流静脉皮瓣存活的可能机制。这些观察结果对于提供一个研究微循环的动物模型以及皮瓣显微外科转移的一个可能新领域可能具有重要意义。
