Abstract
We herein report a case of carotid artery pseudoaneurysm following intensive treatment for hypopharyngeal carcinoma. An
81-year-old male had undergone surgery and concurrent chemoradiotherapy to treat hypopharyngeal carcinoma (T4aN1M0).
This treatment led to a complete response, but pseudoaneurysms were formed at the external carotid artery in a contaminated
wound. One of the pseudoaneurysms was located close to the bifurcation and thus caused intractable hemorrhaging. We performed
endovascular treatment to achieve hemostasis. One year after the embolization, surgical removal of the endovascular
devices from the infected area was performed. Three years have passed since the removal, and the patient is still alive without
any complications. Primary endovascular treatment of an infected pseudoaneurysm could be an effective option for the treatment
of acute lethal hemorrhaging.
