Since plastic surgeons are continually looking for new possibilities for the clinical transfer of tissue, they are very interested in investigating capillary blood flow. Recently, several authors have investigated the role of veins in experimental island venous flaps. In the present study, the authors attempt to clarify the importance of plasmatic imbibition and perivenous tissue as single nourishment sources in experimental island skin flaps deprived of arteries, and consisting of both axial and random zones. This study demonstrates the importance of perivenous areolar tissue in flap survival; the "initial plasmatic imbibition" was not able to keep the flaps viable. Due to the previously demonstrated presence of small arteries in the pedicle of "venous flaps," these flaps should no longer be considered as purely venous. In the reported rat model, it was not possible to harvest a flap without arterial inflow.
由于整形外科医生一直在寻找组织临床转移的新可能性，他们对研究毛细血管血流非常感兴趣。最近，几位作者研究了静脉在实验性岛状静脉皮瓣中的作用。在本研究中，作者试图阐明在没有动脉供应、由轴型和随意型区域组成的实验性岛状皮瓣中，血浆吸收和静脉周围组织作为单一营养来源的重要性。本研究证明了静脉周围疏松结缔组织在皮瓣存活中的重要性；“初始血浆吸收”无法维持皮瓣存活。由于先前已证实在“静脉皮瓣”的蒂部存在小动脉，这些皮瓣不应再被视为纯静脉皮瓣。在报道的大鼠模型中，不可能获取没有动脉血流的皮瓣。
