Methods: A prospective study with 15 pigs divided into a control group (G0, n = 5) undergoing arteriography only, and a triple stent group (G3, n = 10) undergoing arteriography and three stent implantations in the thoracoabdominal aorta. After an eight-day observation, arteriography, euthanasia, and en bloc gastrointestinal harvesting were performed. Lesions were graded using the Park\/Chiu classification, and serum markers were analyzed pre- and post-procedure.  Results: Arteriography confirmed mesenteric artery patency in all animals. Histological analysis showed ischemic lesions in 88.9% of G3, mainly in the colon (89%), compared to 60% in G0, primarily in the colon (60%) and stomach (40%). Most G3 lesions were grade 1, while G0 had higher-grade lesions. Serum markers showed no significant intergroup differences.  Conclusion: Triple stent interposition did not significantly increase gastrointestinal injury, indicating its safety for maintaining gastrointestinal perfusion in this model.<\/jats:p>","DOI":"10.1590\/acb402425","type":"journal-article","created":{"date-parts":[[2025,3,11]],"date-time":"2025-03-11T22:47:18Z","timestamp":1741733238000},"source":"Crossref","is-referenced-by-count":0,"title":["Gastrointestinal
