Aortocaval fistulas are an uncommon complication of atherosclerotic aneurysms that can present with a variety of clinical symptoms. Many of these patients present with oliguric renal failure, a contraindication for the use of iodinated contrast in radiological studies. We present a case of an aortocaval fistula diagnosed by using carbon dioxide gas without the use of traditional contrast media.
主动脉腔静脉瘘是动脉粥样硬化性动脉瘤的一种罕见并发症，可表现出多种临床症状。这些患者中有许多表现为少尿性肾衰竭，这是放射学检查中使用碘化造影剂的禁忌证。我们报告一例通过使用二氧化碳气体而非传统造影剂诊断出的主动脉腔静脉瘘病例。
