ANEURYSM Flashcards
is a dilation of the walls of a cerebral artery that develops as a result ofweaknessin the arterial wall.
intracranialaneurysm
results from a ruptured intracranial aneurysm.
Subarachnoidhemorrhage
Types of Aneurysm
saccular
dissection
mycotic
pseudoaneurysm
cause of the aneurysm
Atherosclerosis
Congenital defect of the vessel wall
Hypertensive vascular disease
Clinical Manifestations of aneurysm
Severe headache
Increased ICP
Focalseizures
Sudden change in the level of consciousness
Nuchal rigidity
Visual disturbances
Possible complications of hemorrhagic stroke include:
Bleeding
Cerebral vasospasm
Acutehydrocephalus
Focal seizures
Surgical Management of aneurysm
Craniotomy
Endovascular treatment
Aneurysm coiling
This is thesurgicalmanagement for the occlusion of the parent artery.
Endovascular treatment
This is the obstruction of the aneurysm site with a coil.
Aneurysm coiling
is a bulge or ballooning in a blood vessel in the brain. An aneurysm often looks like a berry hanging on a stem
A brain aneurysm
also known as a cerebral aneurysm or intracranial aneurysm
A brain aneurysm
If the brain aneurysm leaks or ruptures, it causes bleeding in the brain, known as a
hemorrhagic stroke.
Most often, a ruptured brain aneurysm occurs in the space between the brain and the thin tissues covering the brain. This type of hemorrhagic stroke is called a
subarachnoid hemorrhage
This type of aneurysm looks like a berry hanging from a vine.
Saccular aneurysm
Saccular aneurysm, also known as a
berry aneurysm
It’s a round, blood-filled sac that protrudes from the main artery or one of its branches.
Saccular aneurysm
is the most common type of aneurysm.
A berry aneurysm
This type of aneurysm causes bulging on all sides of the artery.
Fusiform aneurysm
This type of aneurysm is caused by an infection.
Mycotic aneurysm
is the key symptom of a ruptured aneurysm.
A sudden, severe headache
is a procedure to close off an aneurysm.
Surgical clipping
involves accessing the aneurysm by threading a small plastic tube called a catheter through the artery. The catheter is advanced into the brain arteries. Then coils or stents may be placed.
Endovascular treatment
is a newer endovascular treatment option for treatment of a brain aneurysm. The procedure involves placing a stent in the blood vessel to divert blood flow away from the aneurysm.
