Efficacy analysis of endovascular treatment for ruptured internal carotid artery pseudoaneurysm hemorrhage in patients with nasopharyngeal carcinoma after radiotherapy

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.
