The following article has been retracted at the request of the Editor and Publisher:
Liang H-L, Chen MC-Y, Su I-L, Chiang C-L, Chen C. In-valve stent graft placement to reduce edge stenosis for recoil venous anastomotic stenosis in arteriovenous graft hemodialysis patients. The Journal of Vascular Access. 2025;0(0). doi:10.1177/11297298251364334
Following publication, Sage was contacted by a reader who raised concerns about the participant's consent and ethical approval in the study.
When contacted, the corresponding author stated that informed consent for treatment had been obtained from patients or their families and that consent for retrospective review had been waived by an institutional review board (IRB). The authors provided ethical approval documents; however, these did not demonstrate approval covering the full study period. One of the approvals cited in the article was issued to a researcher not listed as an author. An additional approval document provided by the authors was dated after the article’s online publication.
Given the concerns regarding the ethical approval, the Editor and Publisher retract this article.
The authors did not respond when notified of the retraction.
