Histologic Analysis with the Newly Designed Exoskeleton Seal® Stent-Graft in the Porcine Abdominal Aorta

Purpose To investigate the technical feasibility of a novel exoskeleton Seal ® stent-graft and analyze early histologic changes in the porcine abdominal aorta. Materials and Methods Six pigs received an abdominal stent-graft (Group I), and six received an iliac branch stent-graft (Group II). Groups...

Description
Summary:Purpose To investigate the technical feasibility of a novel exoskeleton Seal ® stent-graft and analyze early histologic changes in the porcine abdominal aorta. Materials and Methods Six pigs received an abdominal stent-graft (Group I), and six received an iliac branch stent-graft (Group II). Groups were subdivided as follows: Group Ia, which received three bifurcated main-body stent-grafts; Group Ib, which received three bifurcated main-body stent-grafts with both iliac graft-stents; Group IIa, which received three simple uni-iliac tapered stent-grafts; and Group IIb, which received three uni-iliac tapered tapered stent-grafts with right straight limb and left branched limb. Statistical analyses were performed with the Wilcoxon signed-rank test and mixed-model regression analysis. Results The primary technical success rate (
