Treatment of a Brain Aneurysm
with Detachable Platinum Coils
Tiny platinum coils are threaded through a microcatheter
and pushed into the aneurysm. The coils are flexible
enough to conform to the aneurysm shape.
|
|
|
The aneurysm is filled in with
coils, obstructing the flow of blood into the
aneurysm. Each coil is attached to a delivery
wire, allowing the physician to reposition or
withdraw the coil to ensure ideal placement. Once
properly positioned within the aneurysm, the coil
is detached from the delivery wire using an electrolytic
detachment process (electrical charge).

Angiograms of Aneurysms Pre and Post Treatment
|
|
|
Angiogram of an aneurysm before
treatment. The aneurysm is the dark bulge on the
vessel.
|
|
|
Angiogram of an aneurysm after
endovascular coiling treatment. The aneurysm has
been filled in with coils, so blood can no longer
flow into the aneurysm. The aneurysm now appears
as a silver bulge on the angiogram.

3-D angiography picture of a brain
aneurysm. The aneurysm is the bulge on the vessel
in the middle of the picture. 3-D angiography
is used to determine the dimensions and shape
of aneurysms.
