Disclosures and question data

Which of the following statements regarding arterial embolisation for subdural haemorrhage is TRUE?

embolisation of the middle meningeal arteries is associated with approximately a third of patients needing further surgery.

microcatheter DSA of the middle meningeal artery branches in the setting of large chronic subdual haemorrhage demonstrates characteristic findings of hypervascularity and micro-aneurysms.

platinum coils are used to occlude the middle meningeal artery proximally, to avoid dangerous anastomoses with the ophthalmic artery.

randomised controlled trials have demonstrated that middle meningeal artery embolisation to treat subdural haemorrhage should only be carried out in patients who have failed surgical management.

subdural haemorrhage is characterised histologically by rupture of bridging veins into the border cell matrix on the inner aspect of the meningeal dura.
