This study explored the role of advanced CT angiography (CTA) in diagnosing and managing AVM-related OGIB in 100 patients. CTA identified AVMs in 12% of cases where standard endoscopy failed (p &lt; 0.001) and guided successful surgical control of bleeding in 95% of these cases. The sensitivity of CTA (92%) was significantly higher compared to other imaging modalities (68%; p = 0.002), particularly for small or inaccessible lesions. These findings underscore CTA's crucial role in improving diagnostic accuracy and enabling targeted therapeutic interventions for challenging cases of OGIB.<\/jats:p>","DOI":"10.6026\/9732063002001917","type":"journal-article","created":{"date-parts":[[2025,2,3]],"date-time":"2025-02-03T10:24:32Z","timestamp":1738578272000},"page":"1917-1921","source":"Crossref","is-referenced-by-count":0,"title":["Advanced CT angiography in detecting rare arterio-venous malformations: Addressing diagnostic challenges in obscure gastrointestinal bleeding"],"prefix":"10.6026","volume":"20","author":[{"name":"Department of Medicine, Royal Albert Edward Infirmary, Wigan Wrightington and Leigh Teaching Hospitals NHS Foundation Trust, Wigan, United Kingdom","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Swathi Tapaswi","family":"Kanna","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Kaushik","family":"Rajavel","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"name":"Department of Orthopaedics, Madras Medical College, Chennai, Tamil Nadu, India","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shoa","family":"Nayyer","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"name":"Department of Surgery, Kasturba Medical College, Manipal, Manipal Academy of Higher Education, Manipal Karnataka, India","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Pritika","family":"Gnanasekaran","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"name":"Department of Medicine, Global Medical Centre, Salem, Tamil Nadu, India","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Priyadarshini","family":"Ramesh","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"name":"Department of Obstetrics & Gynaecology, Madras Medical College, Chennai, Tamil Nadu, India","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Anshuman Kumar","family":"Panda","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"name":"Department of Critical Care (ICU), Asian Institute of Medical Sciences, Faridabad, Haryana, India","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"4070","published-online":{"date-parts":[[2024,12,31]]},"container-title":["Bioinformation"],"original-title":[],"deposited":{"date-parts":[[2025,2,3]],"date-time":"2025-02-03T10:24:46Z","timestamp":1738578286000},"score":1,"resource":{"primary":{"URL":"https:\/\/www.bioinformation.net\/020\/9732063002001917.htm"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2024,12,31]]},"references-count":0,"journal-issue":{"issue":"12","published-online":{"date-parts":[[2024,12,31]]},"published-print":{"date-parts":[[2024,12,31]]}},"URL":"https:\/\/doi.org\/10.6026\/9732063002001917","relation":{},"ISSN":["0973-8894","0973-2063"],"issn-type":[{"value":"0973-8894","type":"print"},{"value":"0973-2063","type":"electronic"}],"subject":[],"published":{"date-parts":[[2024,12,31]]}}}
