Methods: From January 2006 to October 2010, 27 anastomosed arteries in 27 replanted digits were included in the study. The patients included nine males and four females. The patients received DSA at 48 to 96 h after digital replantation. Based on DSA image, the blood flow was classified into normal, slow-running, and flow-stopping types. The patients with normal digital blood flow were given continuous routine treatments; the patients with slow-running flow were given the conservative treatments, such as release of the tight dressings, removal of stitches, keeping warm, the use of massage, and the use of anticoagulants and anti-inflammatory drugs; the patients with flow-stopping received immediate surgical re-exploration. Results: In this series, 23 digits in 11 patients showed a normal blood flow, and these digits all survived. In one of 13 patients, two digits which displayed slow-running flow also survived after conservative treatments. In two of 13 patients, two digits showed flow stopping, with one surviving and one failing after re-exploration and arterial revision. Conclusions: The DSA can be used to assess the blood flow of the proper digital artery in the early stage after replantation. It provides essential information for salvaging the replanted finger.展开更多
