Flashcards in Hemorrhagic Stroke Deck (17):
1

What two ethnic/racial groups are at higher risk of deep hemorrhagic stroke?

Asians and other non-white people

2

Which kind of stroke (deep or lobar) has a worse outcome?

Deep

3

Aneurysms often occur at _______ points. Why?

Branch points – because the tunica media is thinnest at branch points

4

Arterio-venous malformations account for what percentage of aneurysms?

15% - 20%

5

AVMs are thought to be ____________.

congenital

6

Compared to subdural hemorrhages, subarachnoid hemorrhages will have ____________ on CT.

finger-like projections into the parenchyma

7

Non-traumatic hemorrhages are most often due to _____________.

hypertension and age

8

Non-traumatic hemorrhages in what type of tissue warrant more investigation?

White matter

9

Smoking is not a risk factor for _____________.

subarachnoid hemorrhage

10

Describe the Hunt and Hess scale for rating subarachnoid hemorrhages.

Grade 1: asymptomatic
Grade 5: coma

11

What pattern of hemorrhage is associated with cerebral amyloid angiopathy?

"Lobar" (also stains Congo red)

12

What is hemorrhagic transformation?

A hemorrhage that is initially caused by an ischemic event; paradoxically, anti-thrombotics help prevent future hemorrhages of this type.

13

__________ hemorrhages are surprisingly well tolerated.

Lobar

14

Which two lobes are most commonly affected by lobar hemorrhages?

Frontal and parietal

15

What type of hemorrhage might be described as "the worst headache of my life"?

Subarachnoid hemorrhage

16

Berry aneurysms most often occur where?

The anterior communicating artery

17

What are arterio-venous malformations?

An abnormal connection between the arteries and the veins that bypasses capillaries
