Rupture of an aortic aneurysm caused by Haemophilus influenzae type B infection

Abstract

A patient was operated for a contained rupture of an aortic aneurysm that appeared to be infected with Haemophilus influenzae type b. Reports on this species as a cause of infection and rupturation of an atherosclerotic aneurysm are extremely rare and we therefore describe this case. Apparently the risk of bacteraemia and the possible effects of it in patients with an aneurysm should be considered in surgical decision-making and management.
