Reconstructive microsurgery is now in a new stage of supermicrosurgery. With this technique, very tiny (0.3mm) vascular anastomoses are possible. In this paper, we describe two cases of successful fingertip replantations employing arteriole (terminal branch of digital artery) anastomoses, the arteriole graft being obtained from the same fingertip defect, reverse arteriole flow to subdermal venule, and delayed venular drainage for venous congestion. These atypical tiny vascular anastomoses were successfully carried out under digital block.
重建显微外科目前正处于超显微外科的新阶段。借助这项技术，非常微小（0.3毫米）的血管吻合成为可能。在本文中，我们描述了两例成功的指尖再植病例，采用了小动脉（指动脉终末分支）吻合，小动脉移植物取自同一指尖缺损处，小动脉逆向血流至皮下小静脉，并采用延迟静脉引流来处理静脉淤血。这些非典型的微小血管吻合在指神经阻滞下成功完成。
