The study aims to assess the postoperative hemostasis rate, postoperative rebleeding rate, complication rate, and 1-year postoperative survival rate.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>During the study period, 36 patients underwent endovascular treatment, of which 24 patients underwent embolization of the internal carotid artery and 12 patients underwent stenting of the internal carotid artery. The procedure success rate was 100%. The rebleeding rate at 1 year after the procedure was 5.6% (2\/36, one patient with stent placement and one patient with coil embolization), and the complication rate was 11.1% (4\/36, four patients with coil embolization patients). Two patients developed large-area cerebral infarction after the procedure, and two patients had different degrees of neurological impairment after the procedure. The 1-year survival rate was 91.7% (33\/36).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>Ruptured internal carotid artery pseudoaneurysm hemorrhage after radiotherapy is rare but life-threatening. Endovascular treatment with coil occlusion or stenting reconstruction of the internal carotid artery provides immediate hemostasis and elimination of the pseudoaneurysm with a low rate of recurrence, which may be effective in reducing patient mortality.<\/jats:p><\/jats:sec>","DOI":"10.3389\/fsurg.2024.1451570","type":"journal-article","created":{"date-parts":[[2024,8,20]],"date-time":"2024-08-20T04:44:33Z","timestamp":1724129073000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":0,"title":["Efficacy
