Haemorrhagic Stroke

Question 1

Types

Answer 1

Intracerebral- bleed in cerebrum

Subarachnoid- between pia and arachnoid mata

Question 2

2 types of intracerebral

Answer 2

Intrapaernchymal- just brain tissue

Intraventricular- extends into ventricles

Question 3

Cerebral artery supplies

Answer 3

Frontal
Parietal
Temporal

Also anterior cerebral artery supplies frontal and parietal

Question 4

Vertebral artery supplies

Answer 4

Occipital and brain stem

Posterior cerebral artery - occipital, temporal, thalamus

Question 5

Reasons for stroke

Answer 5

Hypertension leasing to hyaline arteriosclerosis - causes stiff and brittle arteries so more likely to rupture

Microaneurysms-

Charot- bonchard

Likely to be found in small arteries (lenticulostriate vessels)

Question 6

Haemorrhagic stroke associated with

Answer 6

Arteriovenius malformations

Question 7

Arteeiovenus malformations are

Answer 7

Connect artery to veins

Can burst and cause a stroke

Question 8

Stroke associated with conditions damaging arteries in the cerebrum like

Answer 8

Vasculitis : inflammation of blood vessel walls

Vascular tumours

Cerebral amyloid angiography: protein deposits in walls of arterioles

Question 9

How can haemorrhage be secondary to ishemic stroke

Answer 9

Repercussion to damaged brain tissue
There is a chance of rupture/haemorrhage

Leads to bleeding into dead tissue = haemorrhagic conversion

Question 10

What follows a haemorrhagic stroke

Answer 10

Pool of blood that puts pressure on

Skull
Brain tissue
Blood vessels

Less blood flowing downstream so healthy cells die due to lack of 02 and pressure

Question 11

Increased-pressure leads to herniation of

Answer 11

Fall cerebral
Tentorium cerebelli
Forsaken magnum

Question 12

Treatment drugs

Answer 12

Hypertension

Relieve intracranial pressure

Question 13

Treatment surgery

Answer 13

Craniotomy- part of skull removed to drain blood and relieve pressure

Stereotactic aspiration

Aspirate off blood and relieve pressure
