Ultrasound Velocimetry in the Abdominal Aorta Before and After Endovascular Aneurysm Repair

All patients will undergo an echoPIV measurement 6 to 8 weeks before and 6 to 8 weeks after endovascular aneurysm repair. These measurements will take place at the Vascular Center of Rijnstate Hospital. A venous cannula will be inserted to enable contrast administration. Ultrasound data will be collected at the caudal renal artery, infrarenal neck, aneurysm sac and both iliac arteries.

A 4D phase-contrast magnetic resonance imaging (4D flow MRI) scan of the abdominal aorta will be obtained 6 to 8 weeks before and 6 to 8 weeks after endovascular aneurysm repair.
