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.

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 (< 24 h) was 83% because of two acute thromboses in the lumen of the stented abdominal aorta immediately after stent-graft placement. At 4 weeks, late thrombosis occurred in two pigs. Higher mean neointimal hyperplasia areas (23.5% vs. 16.2%;
P
= .047), neointimal hyperplasia thicknesses (545.5 μm vs. 422.2 μm;
P
= .001), and degrees of collagen deposition (2.71 vs. 2.33;
P
= .002) were observed at the bare-metal stent-graft compared with the proximal exoskeleton portion of the stent-graft, with no significant differences between the patent and occluded groups or among the four types of stent-grafts.
Conclusions
The exoskeleton stent-graft demonstrates 66% of patency rate during 1-month follow-up due to four cases of thromboses; however, the endothelialization on the junction of proximal graft showed no significant differences between the patent and occluded groups. Further studies should investigate long-term outcomes with prolonged neointimal hyperplasia.</description><identifier>ISSN: 0174-1551</identifier><identifier>EISSN: 1432-086X</identifier><identifier>DOI: 10.1007/s00270-019-02261-2</identifier><identifier>PMID: 31201508</identifier><language>eng</language><publisher>New York: Springer US</publisher><subject>Abdomen ; Animals ; AORTA ; Aorta, Abdominal - surgery ; Arterial Interventions ; Bifurcations ; Blood Vessel Prosthesis - statistics & numerical data ; Blood Vessel Prosthesis Implantation - methods ; Cardiology ; COLLAGEN ; CONNECTORS ; Coronary vessels ; EXOSKELETON ; Exoskeletons ; Feasibility Studies ; Grafting ; Grafts ; Hyperplasia ; Imaging ; Implants ; Laboratory Investigation ; LIMBS ; Male ; Medicine ; Medicine & Public Health ; Model testing ; Models, Animal ; Nuclear Medicine ; Prosthesis Design ; Radiology ; RADIOLOGY AND NUCLEAR MEDICINE ; Rank tests ; REGRESSION ANALYSIS ; Statistical analysis ; Stents ; Stents - statistics & numerical data ; Surgical implants ; SWINE ; Thromboembolism ; THROMBOSIS ; Ultrasound ; Vascular Patency</subject><ispartof>Cardiovascular and interventional radiology, 2019-09, Vol.42 (9), p.1331-1342</ispartof><rights>Springer Science+Business Media, LLC, part of Springer Nature and the Cardiovascular and Interventional Radiological Society of Europe (CIRSE) 2019</rights><rights>CardioVascular and Interventional Radiology is a copyright of Springer, (2019).

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.

The primary technical success rate (< 24 h) was 83% because of two acute thromboses in the lumen of the stented abdominal aorta immediately after stent-graft placement. At 4 weeks, late thrombosis occurred in two pigs. Higher mean neointimal hyperplasia areas (23.5% vs. 16.2%;
P
