Intravascular Ultrasound May Not Impact Graft Sizing in Endovascular Repair of Blunt Thoracic Aortic Injury.

IVUS is not associated with significant changes in endograft sizing compared to sizing based on CT scan alone in BTAI patients. IVUS was not associated with differences in mortality but was associated with a decrease in delayed hemorrhagic and ischemic stroke. Routine IVUS in BTAI patients may not be necessary for accurate sizing, but there may be a relationship between IVUS and stroke.
