Massive bleeding from an infected pseudoaneurysm in an arteriovenous graft that resulted in death: A case report.

We report an autopsy of a death due to a ruptured infected pseudoaneurysm; a man in his 70s was found dead with massive bleeding from the shunt of his right arm. Autopsy and pathological examination revealed that the cause of death was hemorrhagic shock due to rupture of an infected pseudoaneurysm. Ruptured aneurysms and pseudoaneurysm are a complication of dialysis, and death is rare because they are treated immediately on discovery. However, these ruptures often occur in non-medical facilities and could result in death if the patient does not have knowledge of first aid. Thus, patient education is important. Approximately only half of the deaths due to massive bleeding from a shunt are autopsied. In Japan, autopsies or partial autopsies are considered necessary to determine whether a bleeding was traumatic and to prevent medical errors from being overlooked.
