Figure 4. Schematic rappresentation of a branched endoprosthetis designed with retrobranch for renal arteries (Innerbranch B and Innerbranch C) and anterograde inner branch for mesenteric superior artery (Innerbranch A). The diameter of the proximal extremity (40 mm), the middle tract (2 mm), and the distal extremity (28 mm) of the endoprosthesis are indicated. Moreover, the distance between the proximal neck and Innerbranch A is shown (100 mm), as well as the distance between Innerbranch A and Innerbranch B (37 mm), between Innerbranch A and Innerbranch C (39 mm), and between Innerbranch C and the distal neck of the device (70 mm). The radiopaque marker along the main body of the endoprosthesis and the inner branch are also indicated to ensure the correct orientation of the device during the deployment.
