Cerebral aneurysm

1. CEREBRAL
ANEURYSM

2. • An aneurysm is a localized or diffuse dilation
of an artery with a diameter at least 50%
greater than the normal size of the artery

3. TYPES
• TRUE ANEURYSM
• FALSE ANEURYSM
According to morphology
• Fusiform
• Saccular
• Dissecting

4. Saccular
• rounded berrylike
outpouchings that arise
from arterial bifurcation
points, most commonly
in the circle of Willis.
• dilatations of a vascular
lumen caused by
weakness of all vessel
wall layers

5. • AN ELONGATED SPINDLE-SHAPED DILATION OF AN
ARTERY
• roughly cylindrical and affects the entire circumference of
the

6. DISSECTING
ANEURYSM
• Pseudoaneurysm
• should be used for encapsulated, cavitated,
paravascular hematomas that communicate with the
arterial lumen
MAY ARISE SPONTANEOUSLY
TRAUMA

7. LOCATION
• A common location of cerebral aneurysms is on
the arteries at the base of the brain, known as
the Circle of Willis.
• Approximately 85% of cerebral aneurysms
develop in the anterior part of the Circle of Willis,

9. • Weakness in blood vessel wall
• Atherosclerosis
• Hypertension
• Severe trauma
• Weakness in blood vessel wall.
• smoking
• Alcohol

10. • NO EARLY SIGNS (some)
• Sudden headache
• Nausea and Vomiting
• Vision impairment
• Loss of Consciousness
• Nuchal rigidity
• Seizures
• Dysphagia
• Pupillary changes

11. DIAGNOSIS
• CT SCAN
• MRI SCANNING
• CT ANGIOGRAPHY

16. MANAGEMENT
• SURGICAL MANAGEMENT
The goal is to eliminate blood flow into the aneurysm
ENDOVASCULAR ANEURYSM REPAIR
CRANIOTOMY + REPAIR

17. • Medical Therapy
smoking cessation and blood pressure control

18. • Surgical Clipping
a V-shaped, silver clip to the neck of an internal
carotid artery aneurysm.
A small metal clip (usually made from titanium) is then
applied to the neck (base) of the aneurysm

19. • Endovascular Coiling
Guglielmi detachable coils, known as GDCs,
are soft wire spirals originally made out of platinum
These coils are deployed (released) into an aneurysm via
a microcatheter that is inserted through the femoral artery
of the leg and carefully advanced into the brain.

20. • The microcatheter is selectively advanced into the
aneurysm itself, and the microcoils are released in a
sequential manner
• Once the coils are released into the aneurysm, the blood
flow pattern within the aneurysm is altered, and the slow
or sluggish remaining blood flow leads to a thrombosis
(clot) of the aneurysm.
• thrombosed aneurysm resists the entry of liquid blood,
providing a seal in a manner similar to a clip.
Endovascular coiling is an attract
