Purpose To evaluate the feasibility of MRI for static and
dynamic assessment of the deployment of thoracic aortic
stent grafts after emergency implantation in trauma patients.
Methods Twenty patients initially presenting with a rupture
of the thoracic aorta were enrolled in this study. All patients
underwent thoracic endovascular aortic repair (TEVAR).
The deployment of the implanted stent graft was assessed
by CTA and MRI, comprising the assessment of the aortic
arch with and without contrast agent, and the assessment of
the motion of the stent graft over the cardiac cycle.
Results The stent graft geometry and motion over the
cardiac cycle were assessable by MRI in all patients. Flowmediated
signal variations in areas of flow acceleration
could be well visualised. No statistically significant differences
in stent-graft diameters were observed between CT
and MRI measurements.
Conclusion MRI appears to be a valuable tool for the
assessment of thoracic stent grafts. It shows similar
performance in the accurate assessment of stent-graft
dimensions to the current gold standard CTA. Its capability
of providing additional functional information and the lack
of ionising radiation and nephrotoxic contrast agents may
make MRI a valuable tool for monitoring patients after
TEVAR.
