A: Enhanced axial CT of the aorta, with an ulcer-like contour (arrow) corresponding to ostial avulsion of the right polar inferior artery (RPIA). B: Oblique coronal views of the right (B1) and the left (B2) arterial vascularization of the kidneys, with two main renal arteries (white arrows), a left polar inferior artery (LPIA – B2, black arrows) and avulsion of the RPIA (B1, black arrow) associated to an infarction of the lower pole of the right kidney (white star).
Figure 2
A: 3D(VR) c-arm cone-beam CT view of the aorta, for calibrated measurements, 3D-roadmap and planning of the stenting. The proximal avulsion of the RPIA looks like a 3.7 mm pseudo-aneurysm of the aorta. B: 18 × 56 mm self-expandable stent with 14-mm balloon remodeling. C: Final angiogram showing perfect positioning of the stent, covering both RPIA and LPIA, associated with non-enhancement of the lower pole of both left and right kidney.
