目的分析移植肾急性排异反应不同时期的血流动力学特征。 方法对 31例肾移植术后发生急性排异反应病人不同时期多普勒超声检查资料作回顾分析。 结果在血肌酐升高前 2 4h内 ,多普勒参数阻力指数(RI)和搏动指数 (PI)增高的为 1 9例。急性排异反应中 ,多普勒参数RI和PI与血肌酐有一定的相关性 ;在急性排异反应治愈过程中 ,多普勒参数RI和PI的恢复与血肌酐的恢复并不同步。 结论彩色多普勒观察移植肾有一定的临床意义 ,但要注意观察时机
Objective To analyze the hemodynamic characteristics of acute rejection in different stages of renal allograft. Methods 31 cases of acute rejection after renal transplantation patients at different stages of Doppler ultrasound data for retrospective analysis. Results Within 24 hours before the rise of serum creatinine, the Doppler parameters index of RI and PI were increased in 19 cases. Acute rejection, Doppler parameters RI and PI and serum creatinine have a certain correlation; acute rejection in the healing process, the recovery of Doppler parameters RI and PI and serum creatinine recovery is not synchronized. Conclusion Color Doppler renal transplantation has some clinical significance, but should pay attention to the timing
