^(99)Tc^m-MIBI肝动态显像评价断指再植术后静脉回流

Evaluation of the venous return in the replanted finger autograft by dynamic ^(99)Tc^m-MIBI imaging

目的 探讨99Tcm 甲氧基异丁基异腈 (MIBI)肝动态显像评价断指再植术后静脉回流的临床价值。方法 14例断指再植患者术后 72h于再植指末端组织内注射99Tcm MIBI74MBq(0 .1mL)后 ,以 30s/帧肝脏连续动态显像 10min。结果 根据肝脏放射性聚集程度和快慢将病例分为 0、Ⅰ、Ⅱ级 3类 ,需作减压手术分别为 4/ 4例、0 / 4例、0 / 6例 (χ2 =8.0、10 .0 ,P <0 .0 1)。结论 99Tcm

Objective To assess the venous return in the patients who had under gone replantation of completely cut off finger(RCCF) by dynamic 99Tc m-MIBI imaging. Methods 74 MBq (0.1 mL) 99Tc m-MIBI was injected in the tip of replanted finger 72 h after operation. Fourteen patients with RCCF were examined by liver dynamic imaging after injection. Results 0, Ⅰ and Ⅱ groups were classified according to the radionuclide accumulation in the liver, the ratios of the cases who were under the necessity of decompression surgery to the cases who were not in the groups were 4/4,0/4,0/6, respectively (χ 2=8.0, 10.0, P<0.01). Conclusion Dynamic 99Tc m-MIBI imaging is an objective and effective method for evaluation of the venous return in the replanted fingers.
