摘要
目的探讨脉冲反向谐波声学造影诊断移植肾动脉狭窄的可行性。方法对15例临床疑诊移植肾动脉狭窄患者进行脉冲反向谐波声学造影,并经DSA血管造影证实。结果注射造影剂22～32s后移植肾动脉显影并呈带状增强,确诊移植肾动脉狭窄12例,移植肾动脉内均见造影剂局部充盈缺损。结论脉冲反向谐波声学造影能完整显示移植肾灌注血管床并增强移植肾动脉局部结构的显现,可能成为诊断移植肾动脉狭窄的又一简便、准确方法。
Objective: To study the feasibility of diagnosis of transplant renal artery stenosis(TRAS) with pulse inversion harmonic contrast imaging(PIHCI). Methods: Fifteen cases were examined with PIHCI who were suspected clinically to suffer from TRAS. The results were compared with those of DSA. Results: The images of transplant renal artery were enhanced at 22～32s after administration of contrast agents, and localized filling defect were seen in 12 cases with TRAS. Conclusion: The transplant renal arteries can be clearly showed by PIHCI, and PIHCI can be used as an accurate method to diagnose TRAS.
