Hemorrhagic- Intracerebal

Question 1

What is an intracerebral haemorrhage

Answer 1

Bleeding within the substance of the brain

Question 2

What are the causes

Answer 2

Hypertension 
Trauma
Bleeding disorder 
Vascular malformation 
Amyloid angiopathy 
Drug abuse

Question 3

Describe the vascular system branching structure

Answer 3

Arteries divide into smaller branches
Into capillaries
Where red blood cells go through single file 
Capillaries interface with tiny venules
Which join together to form veins

Question 4

What is the blood pressure in this structure

Answer 4

Steady decline in blood pressure at each level

Question 5

Why is the blood pressure low at capillary level

Answer 5

If capillaries were exposed to much higher pressures they would rupture

Question 6

So what happens in arteriovenous malformation?

Answer 6

This normal branching structure is absent
Instead there is a large feeder artery entering a nidus of small abnormal arterioles and on the venous side is one large vein

Question 7

What does this malformation cause?

Answer 7

High blood flow through the nidus
Hematoma forms and grows until the pressure surrounding it limits expansion or it decompresses itself by rupturing into the csf system

Question 8

What effect does an intracerebral haemorrhage have

Answer 8

Can have a devastating effect

Can rupture neurons irreversibly
