Accurate prediction of aneurysm expansion is demanding for surgeons and remains difficult. METHODS AND RESULTS: We retrospectively analyzed 157 cases of EVAR for abdominal aortic aneurysm (AAA) using a bifurcated main-body stent-graft. There were 62 cases of aneurysm shrinkage after EVAR, 63 cases of stable aneurysm, and 32 cases of aneurysm expansion. Type I endoleaks were significantly increased in the aneurysm expansion group (EXP) compared with the stable (STB) and shrinkage (SHR) groups (EXP: 15.6% vs. STB: 4.8% vs. SHR: 0%, P=0.005). Type II endoleaks were also significantly increased in EXP (EXP: 65.6% vs. STB: 36.5% vs. SHR: 6.5%, P<0.001). Aneurysm wall enhancement (AWE) on imaging, however, was significantly decreased in the EXP group (EXP: 18.8% vs. STB: 23.8% vs. SHR: 53.2%, P<0.001). In multivariate analysis, the occurrence of type II endoleaks significantly decreased (P<0.001) and that of AWE significantly increased the likelihood of aneurysm shrinkage (P=0.032). CONCLUSIONS: AWE following EVAR may be associated with aneurysm shrinkage.","is_dataset_classified":null,"base_score":2.639057329615259,"endowment":2.639057329615259,"datacite_reuse_total":0,"file_count":0,"downloads":0,"views":0,"has_version_chain":false,"is_dataset":false,"is_oa":false,"pmid":"28954946","pmcid":null,"openalex_id":"https://openalex.org/W2757358183","authors":[],"funders":[],"total_grants":0,"fwci":0.4039,"citation_percentile":0.67594034,"influential_citations":0,"citation_trend":[{"year":2020,"count":2},{"year":2021,"count":3},{"year":2022,"count":1},{"year":2023,"count":3},{"year":2024,"count":2},{"year":2025,"count":2}],"oa_status":"gold","license":null,"oa_locations":[{"url":"https://www.jstage.jst.go.jp/article/circj/82/2/82_CJ-17-0786/_pdf","host_type":"journal"},{"url":"https://www.jstage.jst.go.jp/article/circj/82/2/82_CJ-17-0786/_pdf","host_type":"publisher"},{"url":"https://doi.org/10.1253/circj.cj-17-0786","host_type":"journal"},{"url":"https://pubmed.ncbi.nlm.nih.gov/28954946","host_type":"repository"}],"fields_of_study":["Aortic aneurysm repair treatments","Aortic Disease and Treatment Approaches","Intracranial Aneurysms: Treatment and Complications","Adult","Aged","Aged, 80 and over","Aortic Aneurysm, Abdominal","Aortic Rupture","Contrast Media","Endoleak","Endovascular Procedures","Female","Follow-Up Studies","Humans","Male","Middle Aged","Stents","Thrombosis","Tomography, X-Ray Computed","Treatment Outcome"],"mesh_terms":["Adult","Aged","Aged, 80 and over","Aortic Rupture","Contrast Media","Female","Follow-Up Studies","Humans","Male","Middle Aged","Thrombosis","Tomography, X-Ray Computed","Stents","Treatment Outcome","Aortic Aneurysm, Abdominal","Endovascular Procedures","Endoleak"],"keywords":["Aneurysm","Abdominal aortic aneurysm","Endovascular aneurysm repair","Medicine","Radiology","Computed tomography","Aortic aneurysm","Shrinkage","Materials science","Type Ii Endoleak","Retrospective Cohort","Aneurysm Wall Enhancement"],"sdg_mappings":[],"linked_datasets":[],"clinical_trials":[],"software_tools":[],"database_accessions":[],"source":"live","citation_network_status":"fetched"},"created_at":"2026-07-25T14:37:51.798785Z","pmid":null,"pmcid":null,"fwci":null,"citation_percentile":null,"influential_citations":0,"oa_status":null,"license":null,"views":0,"total_file_size_bytes":0,"version_count":0,"fair_f":null,"fair_a":null,"fair_i":null,"fair_r":null,"fair_zscore":null,"fair_rationale":null,"fair_model":null,"fair_agent_version":null,"fair_fulltext_source":null,"fair_has_llm":null,"fair_computed_at":null,"clinical_trials":[],"software_tools":[],"db_accessions":[],"linked_datasets":[],"topics":[]}
