Fatal subdural haemorrhage following lumbar spinal drainage during repair of thoraco‐abdominal aneurysm

Abstract
A 63‐year‐old male patient collapsed and died from a major subdural haemorrhage 5 days after elective repair of a Type III thoraco‐abdominal aortic aneurysm. The anaesthetic technique had included the use of a lumbar cerebrospinal fluid drain. The management of the patient is described, and the association between subdural haemorrhage and cerebrospinal fluid drainage is discussed.
