• 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

• rounded berrylike
outpouchings that arise
from arterial bifurcation
points, most commonly
in the circle of Willis.

• 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,

• 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
• 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are soft wire spirals originally made out of platinum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.
• The microcatheter is selectively advanced into the
aneurysm itself, and the microcoils are released in a
• 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
