維持透析中に感染を契機に生じた頭蓋外頸動脈仮性動脈瘤の4症例

抄録

Aneurysm of extracranial carotid artery unusually occurs, especially pseudoaneurysm caused by infection. Whereas we face this disease rarely, it can be life-threatening with a high mortality rate. We describe 4 cases of infectious pseudoaneurysm of extracranial carotid artery. All of them had been undergoing hemodialysis, so we recognized that hemodialysis was a risk for infectious pseudoaneurysm.

Some authors have mentioned about the immunodeficiency of hemodialysis patients as the cause of infectious pseudoanyeurysms, but the recurrent shunt-puncture and heparization can be also risk factors.
