摘要
目的：应用二维及三维超声研究移植肾排异反应时形态学特点、血流情况，定量分析体积及血管指数（VI）。方法：发生排异反应的移植肾30例，对照组30例，行移植肾二维及三维超声检查，脱机后行肾脏结构及血流的三维图像重建及显示，二维图像测量肾脏的长、宽、厚径，三维重建后用VOCAL法精测移植肾的体积，结合三维能量多普勒计算VI。结果：三维重建图像测得的移植肾体积改变有统计学意义（P<0.05），与二维测得的长、宽、厚径相比更敏感。VI改变有统计学意义（P<0.05）。结论：在发生排异反应时三维超声体积精测较二维超声显示移植肾大小改变更敏感，VI可以定量反应移植肾灌注减少。
Abstract
Objective: To explore the characteristics of the transplanted kidneys’ morphology, blood flow perfusion when rejection occurred by 2D and 3D ultrasound. The volume and the vascularization index(VI) were analyzed quantitatively. Methods: Thirty transplanted kidneys with rejection and thirty normal transplanted kidneys were examined by 2D and 3D ultrasound. 3D ultrasound imaging was reconstructed off-line. The length, width and height were measured on 2D imaging. The volume and VI were calculated by 3D imaging. Results: The volume of transplanted kidneys in rejection group is significantly different from that of control group(P<0.05). It is more sensitive than the length, the width and the height. There is significant difference of VI between the rejection and the control group(P<0.05). Conclusion: When rejection occurred, the volume of the transplanted kidneys obtained by 3D is more sensitive than the size obtained by 2D. VI can describe the decrease of transplanted kidneys’ blood flow perfusion.
