From: Imaging of Patients with Complex Hemodialysis Arterio-Venous Fistulas using Time-Resolved Dynamic CT Angiography: Comparison with Duplex Ultrasound

Figure 4

Displayed is a 48-year old male patient with new onset of arm pain. The patient had revision surgery due to a failing arterio-venous failure two weeks prior to the examination. Time-resolved dynamic CT angiography displayed an early filling of the efferent vein and a delayed filling of the brachial artery (arrow head) indicating a high-flow shunt (see also supplementary video 1).
