Hemorrhagic stroke accounts for about 13% of stroke cases. It occurs when an artery in the brain leaks or ruptures, which causes bleeding in the surrounding area of the brain. The blood can then accumulate and compress the surrounding brain tissue. The two types of hemorrhagic stroke include intracerebral (within the brain) and subarachnoid hemorrhage. A hemorrhagic stroke can cause:

  • Cerebral Aneurysm
  • Arteriovenous Malformation

An ischemic stroke occurs when an artery supplying blood to an are of the brain becomes blocked by a blood clot. About 80% of all strokes are ischemic strokes. Acute ischemic stroke can cause:

  • Small Vessel Occlusion
  • Large Vessel Occlusion
