Cards

Term
What are the areas affected by HPTN Hemorrhage, presenting symptoms for each area, which has the worst prognosis
Definition

Basal Ganglia:

Hemiparesis,

Lateral ventical bleed

Subcortical White Matter:

Mental Status Change

Thalamus:

Headache

3rd ventricle bleed

Cerebellum:

Risk of Herniation

Compression of 4th ventricle

Pons:

Instant Death/Pin-Point Pupils, Hypothermia, **Worst Prognosis**

Term
How does HPTN cause intracerebral hemorrhage
Definition

Chronic HPTN causes fibrinoid necrosis of small vessels

Penetrating Vessels develop reduced tensile strength of the vessel wall (Charcot-Bouchard Aneurysms)

Transient BP increases cause hemorrhage

Term
Where do brain hemorrhages caused by Amyloid Angiopathy occur, how does it present, and what is the age group
Definition

Subcortical White Matter

Presentation: Alzheimer's-like Dementia

Age Group: >65

 

Term
How does amyloid angiopathy cause intracerebral hemorrhage
Definition
Amyloid deposition in media and adventitia weakening vessel wall
Term
What are the major causes of intracerebral hemorrhages
Definition

HPTN

Amyloid Angiopathy

AV malformations

Drug Use

Trauma

Term
What type of hemorrhage is caused by AV malformations
Definition
Intracerebral or Subarachnoid depending on the location
Term
How do AV malformations typically cause intracranial bleeding
Definition
Form Aneurysms that evenually rupture
Term
What are the drugs associated with causing intracerebral hemorrhages?
Definition

Sympathomimetic: Cocaine, Amphetimines

Antithrombolytics

IV Drugs: cause mycotic aneurysms from endocarditis

Term
What cerebrovascular pathology is cocaine likely to produce in the elderly and in younger adults
Definition

Elderly: Stroke

Younger Adults: Aneurysms

Term
What is the timeframe and progression of neurological deficits produced by intracerebral hemorrhage
Definition

Abrupt onset

Deficits evolve over 12-24 hrs

Term
How does an intracerebral hemorrhage typically present
Definition

Abrupt onset neurological deficits

Headache, Nausea, Vomiting

High BP from Cushing's Reflex

Term
What are the prognostic indicators for intracerebral hemorrhage and when is treatment indicated?
Definition

Progressive lethargy or coma-> BAD

Size of the hematoma

Treatment is only indicated in large cerebellar hemorrhages

Term
What are the major causes of subarachnoid bleeds
Definition

Saccular Aneurysm

Trauma

Vascular Malformations

Mycotic Aneurysms from endocarditis

Term
Where should you look for a subarachnoid bleed on MRI
Definition
Basal Cisterns
Term
Where are the most common site for aneurysms
Definition

ACOM, PCOM, MCA

Basilar tip, PICA

Term
What is the presentation of Subarachnoid Hemorrages
Definition

Nausea/Vomiting

Loss of Consciousness

Menigimus-Worst headache of my life

Stiff neck

PCOM->CNIII palsy

MCA->Hemiparesis

 

Term
What is the treatment for a cerebrovascular aneurysm?
Definition

Clip or coil: elderly should use coil

Prevent Vasospam: fluids, raise BP, nimodipine

Term
What are the complications of aneurysms and what are the treatment options for these complications?
Definition

Vasospasm: Angioplasty

Hydrocephalus: Ventricular drain

Term
What is the prognosis for subarachnoid hemorrhages
Definition

Persistant disability

Major Mortality
