Abstract
The patient was a 66-year-old woman on maintenance hemodialysis. One month after a hemodialysis shunt infection, a deep neck abscess was found in the right carotid sheath, and an incisional drainage of the abscess was performed. The local findings were relieved by daily treatment, but pulsatile bleeding was observed from the wound on the 14th postoperative day. Contrast-enhanced CT revealed an aneurysm at the right carotid bifurcation, and endovascular treatment was performed on the same day. Postoperatively, the abscess cavity disappeared with antimicrobial therapy, and the patient did not relapse. Since there was no evidence of infection in the oral cavity or pharynx, and the patient had a history of hemodialysis shunt infection prior to the onset of the abscess, a prior hematogenous infection was considered to be the cause of the deep neck abscess. We report this case in which endovascular treatment was effective in treating an infected carotid artery aneurysm associated with a deep neck abscess.
