The use of SMI in surveillance of endovascular aneurysm repair (EVAR)

Introduction: Endovascular aneurism repair (EVAR) is the treatment of choice in the repair of abdominal aortic aneurysms. Re-intervention rate is higher for EVAR patients compared with open repair requiring lifelong surveillance. This usually consists of a combination of computed tomography angiography (CTA), colour Doppler ultrasound (CDUS) and plain projection radiography. Due to high cumulative radiation dose and nephrotoxicity of CTA and the poor sensitivity of CDUS, other imaging strategies have been proposed. This study reports the use of a new imaging modality (SMI) for the surveillance of EVAR. Methods:…
