Representative case showing intraprocedural guidance under image fusion. (A) The device was introduced along the true lumen of the abdominal aorta, clearly displayed with fused CTA imaging. (B) The device reached the aortic arch with contrast injection, which confirmed the accuracy of the fused image. (C) Deployment of graft stent and perforation under image fusion guidance at an optimal working angle (arch view). Image fusion showing the centre of the LSA ostium to facilitate the accurate positioning of perforation. (D) Deployment of graft stent and perforation under image fusion guidance (en face view). Real-time three-dimensional fusion guidance reduced repeated angiographies between two common working angles: (E) predilation of balloon under image fusion guidance (arch view); (F) predilation of balloon under image fusion guidance (en face view).
