Follow-up of endovascular aortic aneurysm repair: Preliminary validation of digital tomosynthesis and contrast enhanced ultrasound in detection of medium- to long-term complications

Figure 1 Simplified surveillance protocol for abdominal aortic stent grafts[4]. CTA: Computed tomography angiography.

Figure 2 Summarization of the findings according to the different imaging techniques of a type III endoleak after graft dislocation. (A) Computed tomography angiography with focal contrast-enhancement behind the graft main body during arterial phase contrast shows the presence of endoleak; computed tomography angiography multiplanar MIP reconstruction (B) and antero-posterior digital tomosynthesis of the abdomen (C) shows better visualization of the graft failure with complete dislocation and angulation of the graft main body (white harrows); Ultrasound image of the enlarged aneurismal sac in an axial scan (D) and the visualization of the endoleak with a contrast-enhanced ultrasound scan (arrow indicates the endoleak flux) (E).
