A large extrarenal pseudoaneurysm, originating from the arterial anastomosis of a renal allograft, occurred spontaneously 7 years after transplantation in a 29-year-old diabetic patient. Although the scintigraphic examination was diagnostic of a pseudoaneurysm, pulsed Doppler and color coded Doppler ultrasound failed to demonstrate a Doppler signal, suggesting erroneously a nonvascular fluid collection. The role of scintigraphy combined with duplex ultrasound in this rare but potentially fatal complication of renal transplantation is discussed.
一名29岁的糖尿病患者在肾移植7年后，自发出现了一个源于同种异体肾动脉吻合处的巨大肾外假性动脉瘤。尽管闪烁扫描检查诊断为假性动脉瘤，但脉冲多普勒和彩色编码多普勒超声未能显示多普勒信号，错误地提示为非血管性液体积聚。本文讨论了闪烁扫描结合双功超声在这种罕见但可能致命的肾移植并发症中的作用。
