A few hours later, facial swelling and massive bleeding appeared near the extraction socket involving the posterolateral wall of the maxillary sinus. Angiography showed a pseudoaneurysm involving the posterior superior dental artery, and the lesion was selectively embolized with an N-butyl cyanoacrylate (NBCA)-lipidiol mixture. The second patient underwent removal of the left upper third molar, and massive bleeding occurred from the extraction socket involving the greater palatine foramen. Angiography revealed the pseudoaneurysm of the greater palatine artery, and the lesion was selectively embolized with an NBCA-lipiodol mixture. Both patients were discharged uneventfully, and no recurrent bleeding was observed during the 82- and 5-month follow-up periods.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>LESSONS<\/jats:title>\n                    <jats:p>Massive arterial bleeding after a third molar extraction occurs from either the posterior superior dental artery or the greater palatine artery, which is associated with the location of the extraction socket. Selective transarterial glue embolization is a useful option for the treatment of arterial bleeding after the removal of the upper third molars.<\/jats:p>\n                  <\/jats:sec>","DOI":"10.3171\/case23118","type":"journal-article","created":{"date-parts":[[2023,7,25]],"date-time":"2023-07-25T09:55:19Z","timestamp":1690278919000},"source":"Crossref","is-referenced-by-count":7,"title":["Selective transarterial embolization for arterial hemorrhage after upper third molar extraction: illustrative cases"],"prefix":"10.3171","volume":"6","author":[{"given":"Kohei","family":"Tokuyama","sequence":"first","affiliation":[{"name":"Departments of Radiology and"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hiro","family":"Kiyosue","sequence":"additional","affiliation":[{"name":"Department of Diagnostic Radiology, Kumamoto University Faculty of Life Sciences, Kumamoto, Japan; and"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ryuichi","family":"Shimada","sequence":"additional","affiliation":[{"name":"Departments of Radiology and"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Satomi","family":"Miyamoto","sequence":"additional","affiliation":[{"name":"Department of Radiology, Hamanomachi Hospital, Fukuoka, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ayaka","family":"Abe","sequence":"additional","affiliation":[{"name":"Oral and Maxillofacial Surgery, Oita University Faculty of Medicine, Yufu City, Oita, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kenji","family":"Kawano","sequence":"additional","affiliation":[{"name":"Oral and Maxillofacial Surgery, Oita University Faculty of Medicine, Yufu City, Oita, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yoshiki","family":"Asayama","sequence":"additional","affiliation":[{"name":"Departments of Radiology and"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1754","reference":[{"issue":"1","key":"b1","series-title":"Oral Maxillofac Surg Clin North Am","first-page":"117","article-title":"Complications of third molar surgery","volume":"19","author":"Bouloux GF","year":"2007","unstructured":"Bouloux GF, Steed MB, Perciaccante VJ.
