Adoption in neuroendovascular procedures has been slower due to anatomical challenges, a steeper learning curve, and reliance on transfemoral devices. Shapiro et al. reported a 4.6% total and 1.6% major complication rate with transfemoral mechanical thrombectomy (MT). While transradial MT aims to reduce such risks, small radial arteries pose concerns such as vasospasm and catheter entrapment. For large-bore access sites (&gt;8F), available percutaneous closure options are limited. Vascular closure devices offer immediate hemostasis\u2014even in anticoagulated patients\u2014but data are limited on off-label use in oversized arteriotomies. We present a single-center retrospective experience using a 7F CELT closure device on 9F arteriotomies in MT.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Materials\/Methods<\/jats:title>\n                    <jats:p>We retrospectively reviewed patients from January 2021 to 2023 who underwent endovascular procedures using 9F femoral sheaths closed with a 7F CELT device.
