We report outcomes of patients undergoing UBE for AAP and AIOD.<\/jats:p>\n <\/jats:sec>\n \n Methods<\/jats:title>\n Patients (2016\u20132021) undergoing UBE were identified retrospectively at an academic institution. AAP included aneurysm\/pseudoaneurysm\/PAU. Chi-square and Kaplan-Meier analysis were used to evaluate outcomes by group.<\/jats:p>\n <\/jats:sec>\n \n Results<\/jats:title>\n \n 90 patients undergoing UBE were included with 39 patients undergoing AAP (43%) and AIOD treatment in 51 (57%). AAP patients were older (72.9 vs 62.5\u00a0years;\n p<\/jats:italic>\n = .01), with a lower prevalence of female patients treated than AIOD (36% vs 57%;\n p<\/jats:italic>\n = .04), diabetes (23% vs 45%;\n p<\/jats:italic>\n = .03) and current smokers (46% vs 69%;\n p<\/jats:italic>\n = .03). There were significant differences in arterial diameters with AAP patients exhibiting larger minimum aortic diameter (19\u00a0mm vs 15\u00a0mm;\n p<\/jats:italic>\n < .0001), iliac (12.5\u00a0mm vs 9.8\u00a0mm;\n p<\/jats:italic>\n < .0001), femoral (9\u00a0mm vs 6.9\u00a0mm;\n p<\/jats:italic>\n < .0001), SFA (6.8\u00a0mm vs 5.2\u00a0mm;\n p<\/jats:italic>\n < .0001) and profunda femoris (6\u00a0mm vs 4.9\u00a0mm;\n p<\/jats:italic>\n = .002). Shorter surgery duration was seen with AAP than AIOD patients (135\u00a0min vs 194\u00a0min;\n p<\/jats:italic>\n = .001). There were six major amputations in the overall cohort with two BKA and four AKA. There were no significant differences in unadjusted 30-day outcomes or mid-term outcomes between groups at a mean follow-up period of 20\u00a0months. Reinterventions over the follow-up period occurred in 9 limbs (5%) in the overall cohort with no significant associations between demographic or anatomic variables identified. Subgroup analysis of the whole cohort by sex revealed that female patients exhibited smaller minimum aortic diameter (14.9\u00a0mm vs 18.6\u00a0mm;\n p<\/jats:italic>\n < .0001), common iliac (9.3\u00a0mm vs 12.5\u00a0mm;\n p<\/jats:italic>\n < .0001), femoral (6.9\u00a0mm vs 8.7;\n p<\/jats:italic>\n < .0001), SFA (5.2\u00a0mm vs 6.6\u00a0mm;\n p<\/jats:italic>\n < .0001) and profunda femoris (4.9\u00a0mm vs 5.9\u00a0mm;\n p<\/jats:italic>\n = .0006). Logistic regression analysis revealed an independent association between minimum aortic diameter (OR 1.61; 95% CI 1.0\u20132.4) and surgery length (OR 1.02; 95% CI 1\u20131.03) and overall mortality. Kaplan-Meier estimated survival at 36 months was 94% for AIOD and 84% for AAP (\n p<\/jats:italic>\n = .23). At 36\u00a0months, primary patency was 78% for AIOD versus 100% for AAP (\n p<\/jats:italic>\n = .002), primary-assisted patency was 94% for AIOD versus 100% for AAP (\n p<\/jats:italic>\n = .12) and secondary patency for AIOD was 82% versus 100% for AAP (\n p<\/jats:italic>\n = .008).\n <\/jats:p>\n <\/jats:sec>\n \n Conclusions<\/jats:title>\n UBE can be safely and effectively used for treating aortic aneurysmal pathology as well as aortoiliac occlusive disease in selected patients. Despite the differing pathologies, outcomes are similar with a low reintervention rate and excellent mid-term patency of the intervention. Interestingly, an independent association between mortality and small minimum aortic diameter was seen, further reinforcing AIOD as a marker for overall mortality when compared with aneurysm patients.<\/jats:p>\n <\/jats:sec>","DOI":"10.1177\/17085381251360045","type":"journal-article","created":{"date-parts":[[2025,7,28]],"date-time":"2025-07-28T12:55:21Z","timestamp":1753707321000},"page":"330-341","update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":0,"title":["Outcomes of unibody endoprosthesis for treatment of aortic aneurysmal pathology and aortoiliac occlusive disease"],"prefix":"10.1177","volume":"34","author":[{"given":"Benjamin","family":"Liu","sequence":"first","affiliation":[{"name":"University of Missouri School of Medicine"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Caroline","family":"Chung","sequence":"additional","affiliation":[{"name":"University of Missouri"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Iman","family":"Mohammed","sequence":"additional","affiliation":[{"name":"University of Missouri School of Medicine"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Chase","family":"Schlesselman","sequence":"additional","affiliation":[{"name":"MU-Surgical Center for Outcomes and Research Effectiveness (MU-SCORE)"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7782-1593","authenticated-orcid":false,"given":"Todd R.","family":"Vogel","sequence":"additional","affiliation":[{"name":"MU-Surgical Center for Outcomes and Research Effectiveness (MU-SCORE)"},{"name":"University of Missouri"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Steven","family":"Cheung","sequence":"additional","affiliation":[{"name":"University of Missouri"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3143-5181","authenticated-orcid":false,"given":"Jonathan","family":"Bath","sequence":"additional","affiliation":[{"name":"MU-Surgical Center for Outcomes and Research Effectiveness (MU-SCORE)"},{"name":"University of Missouri"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"179","published-online":{"date-parts":[[2025,7,28]]},"reference":[{"key":"e_1_3_4_2_2","doi-asserted-by":"publisher","DOI":"10.1161\/CIRCULATIONAHA.122.062123"},{"key":"e_1_3_4_3_2","doi-asserted-by":"publisher","DOI":"10.1177\/1526602817730840"},{"key":"e_1_3_4_4_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jvs.2006.12.037"},{"key":"e_1_3_4_5_2","doi-asserted-by":"publisher","DOI":"10.1055\/s-0034-1393976"},{"key":"e_1_3_4_6_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.surg.2008.06.021"},{"key":"e_1_3_4_7_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.ejvs.2015.06.112"},{"key":"e_1_3_4_8_2","doi-asserted-by":"publisher","DOI":"10.5758\/vsi.200051"},{"key":"e_1_3_4_9_2","doi-asserted-by":"publisher","DOI":"10.1016\/j.jvs.2010.04.080"},{"key":"e_1_3_4_10_2","article-title":"Outcomes of endovascular reconstructive techniques in trans-atlantic inter-society Consensus II C-D aortoiliac lesions","author":"Zaca S","year":"2022","unstructured":"Zaca S, Desantis C, Di Stefano L, et al.
