Hemorrhagic Stroke - Coggle Diagram

- - - - Acute thunderclap headache, acute loss of consciousness, nausea/vomiting, seizure
  - - - Catheter inserted into artery towards the aneurysm and coils are inserted into aneurysm until it is filled
  - - - Thunderclap headache, maximal at onset, predominant clinical feature, severe intensity, CT may be normal
      - Minor hemorrhage with rapid thrombus formation within the aneurysm
      - Clinical recognition allows for time window to detect aneurysms
      - If CT normal -> Lumbar Puncture
    - - Cranial nerve 3 palsy from posterior communicating artery aneurysm
- - - - Vasospasms: Can lead to ischemia -> Treated by avoiding hypotension and use CCB to limit vasoconstriction
- - - - Headache, vomiting, Progressive deterioration, Severe hypertension
    - - Blood will appear bright on CT immediately (Hemorrhagic), Decrease in tissue density (dark)
  - - - Hypertension most common cause
      - Cause of small vessel disease leading to microaneurysms in small arteries, responsible for lacunar ischemic infarcts
    - - Involving major lobes of the brain, hemorrhage extends out of cortex
      - Amyloid angiopathy, anticoagulant use or coagulopathy, hemorrhagic conversion of an ischemic infarct, metastic hemorrhage
      - AV Malformations
