To evaluate the clinical value of color Doppler in monitoring graft flow in patients who underwent simultaneous pancreas-kidney (SPK) transplantation.
Totally 18 patients received color Doppler ultrasonography on day 1, 3, and 7 after SPK. Volumes and arteriovenous velocities of the kidney and pancreas grafts were recorded, and resistance index (RI) was calculated.
Color Doppler ultrasound clearly displayed the modality, size, and flow of the kidney and pancreas grafts. Compared with the single kidney grafts, the modality, volume, and arteriovenous velocity of kidney grafts in SPK was not significantly different. Although the volume of pancreas graft was remarkably larger than the normal control pancreas early after transplantation, no difference in artery velocity was found between pancreas graft and normal pancreas. The spectrum of the portal vein in pancreas grafts showed the typical spectrum of iliac veins.
Color Doppler ultrasound is sensitive in monitoring the graft flow of SPK recipients and can be used to identify postoperative vascular complications and evaluate tissue perfusion.
评估彩色多普勒在监测同期胰肾联合移植（SPK）患者移植器官血流中的临床价值。
18例患者在SPK术后第1、3和7天接受彩色多普勒超声检查。记录肾和胰腺移植器官的体积及动静脉血流速度，并计算阻力指数（RI）。
彩色多普勒超声清晰显示了肾和胰腺移植器官的形态、大小及血流情况。与单纯肾移植相比，SPK患者肾移植器官的形态、体积及动静脉血流速度无显著差异。虽然移植术后早期胰腺移植器官的体积明显大于正常对照胰腺，但胰腺移植器官与正常胰腺的动脉血流速度无差异。胰腺移植器官门静脉频谱显示为典型的髂静脉频谱。
彩色多普勒超声对监测SPK受者移植器官血流敏感，可用于识别术后血管并发症并评估组织灌注。
