Haemorrhagic stroke

Most strokes are caused by a blockage in an artery leading to the brain (ischaemic stroke). However, approximately 15% of strokes are caused by bleeding, known as haemorrhagic stroke.

There are two main types of haemorrhagic stroke: bleeding around the brain (called subarachnoid haemorrhage) and bleeding in the brain (called intracerebral haemorrhage). The main cause of subarachnoid haemorrhage is an aneurysm, which may be treated by endovascular coiling or surgery. The main cause of intracerebral haemorrhage is high blood pressure, and patients are treated with medication to lower their blood pressure, and very occasionally they have brain surgery.
