Arteriovenous fistulas (AVFs) are abnormal communications between the arterial and the venous systems. We describe two cases in which an aortocaval fistula (ACF) and a deep femoral AVF were diagnosed on dynamic computer tomography (CT) by early transient enhancement of the inferior vena cava (IVC). Awareness of the specific CT features found in central and peripheral AVFs and the effects on the arterial and venous systems may enable the radiologist to make the diagnosis.
动静脉瘘（AVF）是动脉系统与静脉系统之间的异常连通。我们描述了两例病例，其中通过动态计算机断层扫描（CT）下腔静脉（IVC）早期短暂强化诊断出主动脉腔静脉瘘（ACF）和股深动静脉瘘。了解中央型和周围型动静脉瘘的特定CT特征以及对动脉和静脉系统的影响，可能有助于放射科医生做出诊断。
