摘　　要：目的总结肾移植术后可疑移植肾动脉狭窄(TRAS)患者肾动脉吻合口血流速度恢复特点。方法经彩色多普勒超声检查诊断为肾移植术后可疑TRAS的患者149例,肾移植术后6个月时复查彩色多普勒超声,观察不同性别(男、女)、不同年龄[青中年(15~45岁)、中老年(46~75岁)]、不同治疗措施的患者肾动脉吻合口血流速度恢复情况,其中肾动脉吻合口收缩期峰值血流速度<150 cm/s者判定为血流速度恢复正常。结果肾移植术后6个月时,149例肾移植术后可疑TRAS患者中,128例肾动脉吻合口血流速度恢复正常,占比85.9%。其中男性患者肾动脉吻合口血流速度恢复正常者占80.2%,女性患者肾动脉吻合口血流速度恢复正常者占92.6%,两者相比,P<0.05。青中年男性患者肾动脉吻合口血流速度恢复正常者占76.0%,中老年男性患者肾动脉吻合口血流速度恢复正常者占87.1%,青中年女性患者肾动脉吻合口血流速度恢复正常者占100.0%,中老年女性患者肾动脉吻合口血流速度恢复正常者占88.0%,其中青中年女性患者肾动脉吻合口血流速度恢复者比例最高(P均<0.05)。17例进行介入治疗干预的患者中,12例患者肾动脉吻合口血流速度恢复正常,占比70.6%;132例未进行介入治疗干预的患者中,116例患者肾动脉吻合口血流速度恢复正常,占比87.9%;两者相比,P>0.05。结论肾移植术后可疑TRAS患者肾动脉吻合口血流速度恢复情况较好,其中女性患者肾动脉吻合口血流速度恢复正常比例高于男性,特别是青中年女性患者肾动脉吻合口血流速度恢复正常比例最高。肾移植术后可疑TRAS患者肾动脉吻合口血流速度恢复情况与是否进行介入治疗无关。Objective To summarize the characteristics of blood flow velocity recovery at the renal artery anastomotic site in patients with suspected transplant renal artery stenosis(TRAS)after kidney transplantation.Methods A total of 149 patients diagnosed with suspected TRAS by color Doppler ultrasound after kidney transplantation were re-examined with color Doppler ultrasound at 6 months postoperatively.The recovery of blood flow velocity at the renal artery anastomosis site was observed across different genders(male,female),age groups[young and middle-aged(15-45 years),middleaged and elderly(46-75 years)],and treatment measures.A peak systolic blood flow velocity<150 cm/s at the anastomosis site was defined as normalized blood flow velocity.Results At 6 months postoperatively,128 out of 149 patients(85.9%)achieved normalized blood flow velocity at the renal artery anastomosis site.The normalization rate was significantly higher in female patients(92.6%)than in male patients(80.2%)(P<0.05).Among male patients,normalization rates were 76.0%in the young and middle-aged individuals versus 87.1%in the middle-aged and elderly individuals.Among female patients,the rates were 100.0%in the young and middle-aged individuals versus 88.0%in the middle-aged and elderly individuals,with the highest proportion observed in the young and middle-aged females(all P<0.05).Of the 17 patients who underwent interventional therapy,12(70.6%)achieved normalization.Among the 132 patients who did not receive interventional treatment intervention,the blood flow velocity at the renal artery anastomosis of 116 patients returned to normal,accounting for 87.9%,and there was no significant difference between these two groups(P>0.05).Conclusions Patients with suspected TRAS after kidney transplantation showed favorable recovery of blood flow velocity at the renal artery anastomosis site.Female patients,particularly young and middle-aged females,exhibited higher normalization rates compared to males.The recovery of blood flow velocity was not associated
