Objective: To investigate the treatment of ruptured pseudoaneurysm of internal carotid artery after radiotherapy for nasopharyngeal carcinoma.

Methods: From June 2012 to May 2019, 11 patients with pseudoaneurysmal hemorrhage of internal carotid artery diagnosed after radiotherapy for nasopharyngeal carcinoma were reviewed, including 8 males and 3 females, with an average age of 53.7 years.

Result: Three patients died of massive hemorrhage after nasal packing and not receiving DSA treatment in time. One patient died of massive hemorrhage during DSA treatment without nasal packing. Three patients underwent anterior and posterior nasal packing and DSA was implanted with covered stent to survive. Two patients were treated with DSA spring coil occlusion because they could not implant the covered stent after nasal packing. One patient survived and one died of brain edema. One case underwent DSA examination after anterior and posterior nasal packing. It was found that the pseudoaneurysm of internal carotid artery was ruptured and the covered stent could not be implanted. BOT test was positive. After superficial temporal artery bypass with middle cerebral artery, the internal carotid artery was embolized and survived.

Conclusion: Internal carotid artery hemorrhage after radiotherapy for nasopharyngeal carcinoma can be effectively treated by DSA implantation after nasal packing.
