The bird beak configuration has no adverse effect in a magnetic resonance functional analysis of thoracic stent grafts after traumatic aortic transection.

Background: This study used magnetic resonance imaging (MRI) to analyze functional long-term outcome after endovascular repair of blunt aortic injury.

Methods: This prospective study enrolled 27 of 53 patients who were treated between 1999 and 2008. Patients underwent functional multidimensional contrast-enhanced MRI with flow analysis or compliance measurements of the aorta, or both.
