Objective: A case of common carotid artery pseudoaneurysm that developed after treatment for malignant neoplasm of the neck in which rupture could be prevented by covered stent placement is reported.
Case Presentation: A 51-year-old woman developed pseudoaneurysm of the common carotid artery after radiotherapy and surgery for hypopharynx cancer. Since direct surgery was considered difficult due to the risk of rupture, endovascular treatment was performed. The lesion disappeared after placement of a covered stent (Fluency Plus; Bard Peripheral Vascular, Tempe, AZ, USA) in the common carotid artery via the femoral artery. No perioperative complication was observed, and the lesion remained obliterated after 5 months. While the patient died due to recurrence of cancer half a year after surgery, no ischemic stroke or rupture of pseudoaneurysm was noted.
Conclusion: Endovascular treatment using a covered stent was useful for the prevention of rupture of pseudoaneurysm that occurred after treatment for malignant tumor of the neck.
