1 Geometrical consequences of kissing stents and the Covered Endovascular Reconstruction of the Aortic Bifurcation configuration in an in vitro model for endovascular reconstruction of aortic bifurcation  Erik Groot Jebbink, MSc, Frederike A.B. Grimme, MD, Peter C.J.M. Goverde, MD, Jacques A. van Oostayen, MD, Cornelis H. Slump, PhD, Michel M.P.J.

2 Fig 1 Still color photographs, Rontgen images, and bronchoscopic images of A, self-expandable nitinol kissing stents (KS); B, Balloon-expandable kissing covered (KC) stents; C, Covered Endovascular Reconstruction of the Aortic Bifurcation (CERAB)-1 with the limbs starting in the tapered part of the aortic cuff; D, CERAB-2 with the iliac limbs starting just above the tapered segment of the aortic cuff.

3 Fig 2 D-ratios of the four different configurations. A ratio of 1 indicates a circular conformation of the stent, whereas ratios higher than 1 indicate more elliptical conformation. Starting point of the graph is the proximal side of the iliac limbs. BMK, Bare metal kissing; CERAB, Covered Endovascular Reconstruction of the Aortic Bifurcation; KC, kissing covered.

4 Fig 3 Axial slices of the computed tomography (CT) scans of the inflow portions of the four models. A, Self-expandable nitinol kissing stents (KS); B, Balloon-expandable kissing covered (KC) stents; C, Covered Endovascular Reconstruction of the Aortic Bifurcation (CERAB)-1 with the limbs starting in the tapered part of the aortic cuff; D, CERAB-2 with the iliac limbs starting just above the tapered segment of the aortic cuff.

5 Fig 4 Geometric mismatch volumes of the four stent configurations as measured with a custom written script, used to segment the whole mismatch volume in each slice by hand, through the use of a polygon approximation. A, Self-expandable nitinol kissing stents (KS); B, Balloon-expandable kissing covered (KC) stents; C, Covered Endovascular Reconstruction of the Aortic Bifurcation (CERAB)-1 with the limbs starting in the tapered part of the aortic cuff; D, CERAB-2 with the iliac limbs starting just above the tapered segment of the aortic cuff.
