Hughes suffered a catastrophic bleed in his brain in the freak cricket accident, in which his skull was fractured after he was struck by a ball in a vulnerable part of his head not protected by his helmet.
The fracture occurred near the large vessels that transport blood to the brain, damaging one, which quickly caused heavy bleeding.
Such subdural haematomas are dangerous not only because the pressure caused by the blood pooling in one place can crush the brain, but also because it blocks blood from entering to provide the brain with the oxygen it needs to survive.
Questions remain about why it took more than an hour from when Hughes was struck by the ball at 2:23pm until he arrived at St Vincent's Hospital for emergency surgery.
A leading Sydney emergency doctor, who declined to be named, said it appeared a substantial amount of time was spent stabilising Hughes at the site of the accident, rather than getting him to hospital where he could be treated.
