CVA Hemorrhagic Flashcards
What are the primary Hemorrhagic strokes?
Intracranial and subarachnoid bleeds
Which type of stroke usually has more severe deficits: ischemic or hemorrhagic?
Hemorrhagic
What area of the brain has a bleed if there is subarachnoid bleeding?
the back of the head
What are 80% of hemorrhagic strokes related to: big vessels or small?
Most are from spontaneous rupture of small vessels that can turn into big bleeds
What is the chief cause of hemorrhagic stroke?
Hypertension - a lot of patients don’t know or they are not compliant with care.
second is brittle vessels
How can you tell someone is hypertensive?
Bright red face with popping vessels
Fatigued
Overweight
What is a major cause for subarachnoid bleeds specifically?
Aneurysm due to the bulging breaking in 50% of subarachnoid cases
Why are diabetics at high risk for hemorrhagic stroke?
Their vessels are brittle
What causes symptoms to show for a hemorrhagic stroke?
Pressure on the cranial nerves due to the bleeding, the feeling of the aneurysm, or AVM
What happens to ICP during hemorrhage?
What does this cause?
Exposure of blood causes an increase in ICP - which in turn causes ischemia from the pressure and vasospasms.
What BP do we want for someone with a hemorrhagic stroke?
High. 160-180
Why do we want to maintain a high BP of someone with a hemorrhagic stroke?
Their body is used to that high pressure. And if we were to drop it too low, we would cause vasospam tightening that makes it worse.
What are the most common locations for bleeding with a hemorrhage?
Cerebral lobes Basal ganglia Thalamus Brain stem (mostly pons) Cerebellum
Why is it that a hemorrhage patient could end up with the intra-ventricular hemorrhage on top of their already existing hemorrhage (in the ventricles)?
Why is this important to avoid?
Rupture of the lateral ventricle can occur and cause more pressure on the ventricles and then the bleed is even bigger.
If it gets to this point, they will be losing a lot of blood and its very fatal.
How long does it take for an aneurysm vessel to dilate?
Can go on for a while. Maybe even a week to months. And you can have multiple ones growing at a time.
