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

Thoracic endovascular aortic repair (TEVAR) is the preferred treatment for severe blunt thoracic aortic injuries (BTAI). Successful outcomes rely on accurate endograft sizing, but initial imaging may underestimate aortic diameters. This study examines the impact of intravascular ultrasound (IVUS) on endograft sizing and clinical outcomes in BTAI patients.
