Radiology
& Operative Images of Brain Aneurysms: |
|
This section
includes radiology and intraoperative images of brain aneurysms.
A brief description of each image is included alongside it.
Depending on your connection speed, these images may take
some time to download. There are three banks of 7 images.
This is the second of the three image banks.

Image 8.
This is a cerebral angiogram image of an aneurysm that
underwent apparently successful coiling (green arrowheads),
but on the followup study, the neck of the aneurysm
(yellow arrow) was found to have regrown. The parent
artery (P) from which the aneurysm
arose is also seen. |
| |
|
 |
Image 9. This
is a magnetic resonance angiogram (MRA) image of the
same aneurysm shown in Image 8. Again, the green arrowheads
show the coil mass in the aneurysm dome, while the yellow
arrow points to the regrown aneurysm neck. The parent
artery (P) is also seen here. |
| |
|
 |
Image 10. The
cerebral angiogram image shows another apparently successfully
coiled aneurysm (yellow arrow). The green arrowheads
point to the internal carotid artery as it makes its
way to the brain from the upper neck and through the
skull base. |
| |
|
 |
Image 11. This
magnetic resonance angiogram (MRA) image shows an aneurysm
that ruptured some time after coiling was carried out.
The parent artery is shown (P), as
is the neck of the aneurysm (black arrow) and the coils
(marked by the green arrowheads) sticking out of the
aneurysm's dome following rupture. |
| |
|
 |
Image 12. The
aneurysm shown in Image 11 is now seen intraoperatively
in Image 12. Here, you can see the coils (green arrowheads)
as they make their way through the thin aneurysm wall.
The neck of the aneurysm is marked by the black arrow,
and the parent artery (P) is also seen. |
| |
|
 |
Image 13. The
aneurysm shown in Images 11 and 12 is now being definitively
clipped. A small curved-tip titanium clip is being deployed
via a "clip applier" (CA).
The green arrowheads point to the jaws of the clip which
are applied in such a way to wrap around and compress
the aneurysm neck (black arrow), while not disturbing
any of the surrounding critical nerve and vascular tissue.
A surgical sucker tip (S) and retractor
blade (R) are also shown. Parent artery
(P) is also seen. |
| |
|
 |
Image 14. The
cerebral angiogram shows a large aneurysm arising from
the anterior communicating artery (the parent artery,
P, in this case). The dome is marked by the green arrowhead,
the neck by the yellow arrow. |
