In reconstructive microsurgery, it is occasionally advantageous to use long recipient or donor vessels for optimal flap inset. These long vessels are prone to kinking or torsion along their longitudinal axis from vessel distension during blood inflow and rising blood pressure. More often than arteries, the veins can also be compressed by overlying tissue sutured under tension or by developing edema. Reanastomosis can no longer be feasible or desirable for several reasons, and the elongated vessels may have to be shifted to a curved course. To avoid detrimental kinking or torsion, fibrin glue can be administered along this new vessel course in order to ensure stabilization. In 20 such cases, we successfully avoided complications when the danger of kinking, torsion, or vein compression was evident after successful anastomosis. On the basis of this experience, we recommend the use of fibrin glue in microsurgical procedures, especially for vessels in intricate geometrical locations.
在重建显微外科手术中,为了实现皮瓣的最佳植入,偶尔使用较长的受区或供区血管是有利的。这些长血管在血液流入和血压升高导致血管扩张时,容易沿其纵轴发生扭结或扭曲。与动脉相比,静脉更常受到张力下缝合的覆盖组织或水肿的压迫。由于多种原因,再次吻合可能不再可行或可取,并且拉长的血管可能不得不改为弯曲的路径。为避免有害的扭结或扭曲,可以沿着这条新的血管路径应用纤维蛋白胶以确保稳定。在20例此类病例中,当吻合成功后扭结、扭曲或静脉受压的危险明显时,我们成功避免了并发症。基于这一经验,我们建议在显微外科手术中使用纤维蛋白胶,特别是对于处于复杂几何位置的血管。
