In 2001 a 13-year-old girl was taken to hospital after car accident, injured by multiple traumas, including an aortic rupture loco typico. Bleeding was brought under control via an endovascular approach with a Gore (W. L. Gore and Associates, Flagstaff, Ariz, USA) iliac limb 14-16-7. Follow-up CT scans showed over the years a relevant, but constant, bird-beak configuration of the stent graft. In 2009 the patient developed progressive arterial hypertension with a secondary hyperparathyroidism. For further investigation a conventional angiography with pressure gradient measurement and a four-dimensional magnetic resonance imaging was performed. The quantitative flow measurements were obtained by means of a retrospective ECG gated cardiacphase resolved three-dimensional T1 weighted fast gradient echo acquisition
