Abstract:
Objective To explore feasibility of monitoring the extremital arterial blood supply and venous blood circulation in rabbits with replanted limb by Na~(99m)TcO_4 trace imaging(TTI). Methods TTI was performed on 6 normal control rabbits and 30 rabbits with replanted limb at 24~36h after replantation. The radioactivity uptake ratio of replanted limb/normal limb(T/NT) was analyzed. Imaging was classified into ?,Ⅰ,Ⅱand Ⅲ scales according to the accumulation amount of extremital radionuclide. Then an exploratory operation was performed on each rabbit. Results Rabbits with ?,Ⅰ,Ⅱand Ⅳ scales had 8,6,15(including 6 normal control rabbits),and 7 animals, respectively, and their T/NT were 0.178?0.072, 0.461?0.046, 0.816?0.074, 1.14?0.086(P1.05) may serve as a qualitative and semiquantitative diagnostic standard for venous blood circulation block. Conclusion TTI was feasible in monitoring the extremital arterial blood supply and venous blood circulation in patients with replanted limb(finger).
