Tc-99m-DTPA renal scintigraphy was performed before and after transcatheter coil embolization in a patient with renal arteriovenous fistula (AVF). Before embolization, scintigraphy showed a characteristic accumulation pattern compatible with the hemodynamics of an aneurysmal type of AVF in the vascular phase. After embolization, the effects of treatment, such as a change in the split renal function on the treated-side and the disappearance of the shunt flow through the fistula were evident. It was concluded that dynamic renal scintigraphy was very useful for patients with an aneurysmal type of renal AVF scheduled for transcatheter embolization.
在一名肾动静脉瘘（AVF）患者中，于经导管弹簧圈栓塞术前后进行了锝-99m-二乙三胺五乙酸（Tc-99m-DTPA）肾闪烁显像。栓塞术前，闪烁显像在血管期显示出与动脉瘤型AVF血流动力学相符的特征性积聚模式。栓塞术后，治疗效果明显，如患侧分肾功能的变化以及经瘘管分流血流的消失。得出结论，动态肾闪烁显像对于计划行经导管栓塞术的动脉瘤型肾AVF患者非常有用。
