An experimental study : Transfer of a pedicled venous flap containing perivenous areolar tissue and nerve.

我们实验评估了带蒂静脉瓣与静脉周围的乳晕组织转移到异位的可行性，并研究了每条静脉、静脉周围的乳晕组织和神经在带蒂静脉瓣的生存能力中的作用。制作5组皮瓣，第1组（N=11）包含静脉周围乳晕组织和引流静脉；第二组：静脉周围乳晕组织（N=10），引流静脉和神经；第三组：（N= 10）仅静脉周围网状组织；第4组：静脉周围乳晕组织和神经；第5组（N=6）只引流静脉。移植后14天进行宏观、血管造影和组织学检查。1、2、3、4、5组包括浅表坏死的总生存面积分别为52.7%、825%、0%、225%、0%。1组与2组患者的平均生存面积及包括表面坏死在内的平均总生存面积差异均有统计学意义（p < 0.05）。di-substituted [O.O5)。第3组和第5组皮瓣全部坏死。这些数据表明，保留静脉是必要条件，通过保留的神经和网状组织内的小血管网络的额外动脉流动可能在皮瓣存活中起重要作用。

we evaluated experimentally the feasibility of transferring a pedicled venous flap with perivenous areolar tissue into an ectopic site, and investigated the role of each vein, the perivenous areolar tissue and nerve in the viability of pedicle venous flaps. Five groups of flaps were created Group 1 : (N=11) containing perivenous areolar tissue and a draining vein ; Group 2 : (N=10) perivenous areolar tissue, a draining vein and nerve ; Group 3 : (N=1O) only perivenous areolar tissue ; Group 4 : (N=6) perivenous areolar tissue and nerve ; Group 5 : (N=6) only draining vein.Macroscopic, angiographic and histological assessments were performed 14 days after transfer. Total survival area including superficial necrosis of Group 1,2,3,4 and 5 were 52.7%, 825%, 0%, 225% and 0% respectively. There were significant differences in mean survival area and mean total survival area including superficial necrosis between Group 1 and Group 2 (p(]SY.di-substituted right.[)O.O5). In contrast, all flaps in Group 3 and Group 5 became necrotic. These data suggest that a preserved vein is the necessary condition and additional arterial flow through the preserved nerve and a small vascular network within the areolar tissue may play an important role in flap survival.
