Appropriate intraoperative assessment is crucial for ensuring technical success and long-term patency. This study assesses intra-arterial pressure measurement (IAPM), and cone beam computed tomography (CBCT) for detecting residual stenosis during SMA stenting in CMI. Methods: This prospective study included 50 consecutive elective patients with symptomatic, significant SMA stenosis scheduled for EVT. The patients in this study were a subset of an ongoing randomized trial with a different primary objective. Intraoperative diagnostic tools\u2014digital subtraction angiography (DSA), IAPM and CBCT were performed after stent placement. Technical success was defined as &lt;30% residual stenosis on DSA, a residual pressure gradient of &lt;10 mmHg with IAPM and full stent expansion on CBCT. Results: Although there was a fair agreement between DSA and CBCT (Kappa 0.294, p = 0.024), the Odds ratio suggests that DSA detected fewer positive cases compared to CBCT (Odds ratio 0.176; 95% CI: 0.004\u20131.37; p = 0.13). DSA also differed significantly from IAPM (Kappa = 0.016, p = 0.882), (Odds ratio = 0.167; 95% CI: 0.018\u20130.749; p = 0.013), suggesting DSA under-detects residual stenosis (&gt;10 mmHg). No significant difference was found between CBCT and IAPM (Kappa = 0.201, p = 0.161) (Odds ratio: 2.25, 95% CI: 0.628\u201310.0%; p = 0.27) indicating comparable results. Conclusions: DSA overlooks clinically important residual stenosis that could be treated during the primary procedure. CBCT aids structural assessment of the stent and allows for on-table optimizing of the procedural outcomes.<\/jats:p>","DOI":"10.3390\/jcm14238507","type":"journal-article","created":{"date-parts":[[2025,12,8]],"date-time":"2025-12-08T16:20:29Z","timestamp":1765210829000},"page":"8507","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Intraoperative Diagnostic Methods for Superior Mesenteric Artery Stenting in Chronic Mesenteric Ischemia"],"prefix":"10.3390","volume":"14","author":[{"given":"Alexandra A.","family":"Brandtz\u00e4g","sequence":"first","affiliation":[{"name":"Department of Vascular Surgery, The Heart Center, Copenhagen University Hospital-Rigshospitalet, 2100 Copenhagen, Denmark"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7930-3842","authenticated-orcid":false,"given":"Jonas P.","family":"Eiberg","sequence":"additional","affiliation":[{"name":"Department of Vascular Surgery, The Heart Center, Copenhagen University Hospital-Rigshospitalet, 2100 Copenhagen, Denmark"},{"name":"Department of Clinical Medicine, Faculty of Health and Medical Sciences, University of Copenhagen, 2200 Copenhagen, Denmark"},{"name":"Copenhagen Academy for Medical Education and Simulation (CAMES), Centre for HR & Education, The Capital Region of Denmark, 2100 Copenhagen, Denmark"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mikkel","family":"Taudorf","sequence":"additional","affiliation":[{"name":"Department of Clinical Medicine, Faculty of Health and Medical Sciences, University of Copenhagen, 2200 Copenhagen, Denmark"},{"name":"Department of Radiology, Copenhagen University Hospital-Rigshospitalet, 2100 Copenhagen, Denmark"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2089-5211","authenticated-orcid":false,"given":"Lars","family":"Lonn","sequence":"additional","affiliation":[{"name":"Department of Clinical Medicine, Faculty of Health and Medical Sciences, University of Copenhagen, 2200 Copenhagen, Denmark"},{"name":"Department of Radiology, Copenhagen University Hospital-Rigshospitalet, 2100 Copenhagen, Denmark"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Timothy A.","family":"Resch","sequence":"additional","affiliation":[{"name":"Department of Vascular Surgery, The Heart Center, Copenhagen University Hospital-Rigshospitalet, 2100 Copenhagen, Denmark"},{"name":"Department of Clinical Medicine, Faculty of Health and Medical Sciences, University of Copenhagen, 2200 Copenhagen, Denmark"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2025,11,30]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"153","DOI":"10.1016\/j.ejvs.2025.06.010","article-title":"European Society for Vascular Surgery (ESVS) 2025 Clinical Practice Guidelines on the Management of Diseases of the Mesenteric and Renal Arteries and Veins","volume":"70","author":"Koelemay","year":"2025","journal-title":"Eur.
