While endoscopic hemostasis remains prominent therapy, its efficacy is limited in emergency settings by poor bowel preparation and obscured visualization. Rectal arterial embolization (RAE) offers a viable alternative, however, detailed descriptions of its application for AHRU in literature are lacking. Thus, we report a single-center experience of RAE in six patients with massive AHRU-related bleeding. Technical success was achieved in 83% (5\/6) of cases, with clinical success was achieved in 100% cases (6\/6). Rebleeding after initial RAE procedure occurred in 33% (2\/6) of cases, one of which ultimately achieving hemostasis through transanal suturing after initial embolization failure. No major embolism-related complications were observed during follow-up. Moreover, complete embolization of rectal supplies demonstrated potential to reduce rebleeding risk, and empiric embolization may hold promise for managing refractory AHRU hemorrhage. These findings advocate for RAE as an effective alternative for AHRU hemorrhage, though further validation in larger cohorts is essential.<\/jats:p>","DOI":"10.1177\/00368504251344186","type":"journal-article","created":{"date-parts":[[2025,5,19]],"date-time":"2025-05-19T18:49:01Z","timestamp":1747680541000},"update-policy":"https:\/\/doi.org\/10.1177\/sage-journals-update-policy","source":"Crossref","is-referenced-by-count":2,"title":["Rectal
