Contrast-enhanced Ultrasound versus Computed Tomographic Angiography for Surveillance of Endovascular Abdominal Aortic Aneurysm Repair

Contrast-enhanced US may be an alternative to CT angiography in the follow-up of patients after EVAR. As US reduces exposure to the biologic hazards associated with lifelong annual CT angiography, including cumulative radiation dose and nephrotoxic contrast agent load, contrast-enhanced US might be considered as a substitute for CT angiography in the surveillance of patients after EVAR.
