Abstract:
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.
