Objective: Fenestrated and branched endovascular aortic aneurysm repair has revolutionized the treatment of complex aortic aneurysms. These improvements, however, have come at the cost of increased radiation exposure and contrast agents use. The purpose of this video is to describe a fast, simple, and reliable imaging guiding technique that effectively facilitates and verifies the catheterization of target vessels, inner branches and contralateral gates using live intravascular ultrasound (IVUS). Methods: We use live IVUS during F-EVAR procedures to confirm branch catheterization and dimeter and length of target vessel, verify discrepancies of the 3D fusion overlay, guide septum perforation in aortic dissection and confirm patency of the branches. Results: Technical success was 100%. We identified a significant decrease in contrast volume and radiation exposure during the procedures using those techniques. Conclusion: The use of IVUS results in reduced contrast and radiation doses to the patient and the operating team.
