We report a case of aortocaval fistula demonstrated with gadolinium-enhanced magnetic resonance (MR) angiography. Specific radiographic features of this rare complication, such as early and intense enhancement of the inferior vena cava, are underlined with MR imaging. The exact location of the fistula can also be assessed with this noninvasive imaging technique. Moreover, the absence of iodinated contrast media makes it particularly suited for stable patients with renal insufficiency. A complete preoperative assessment of abdominal aortic aneurysm can be performed with MR imaging.
我们报告了一例通过钆增强磁共振（MR）血管造影显示的主动脉腔静脉瘘病例。这种罕见并发症的特定影像学特征，如下腔静脉早期和强烈强化，在MR成像中得到凸显。瘘管的确切位置也可通过这种非侵入性成像技术进行评估。此外，不含碘化造影剂使其特别适用于肾功能不全的稳定患者。利用MR成像可对腹主动脉瘤进行完整的术前评估。
