Slide 213: Berry aneurysm
 |
It’s called a berry aneurysm because it
looks like a little berry. It’s not named for Thadeus J. Berry. Very thin
walled, you can imagine what will happen when this thing ruptures.
See this slide with the
virtual microscope. |

It’s easy to see the aneurysm expanding off
the edge of this elastic artery. Where in the vascular system do you
anticipate seeing such a aneurysm? What would be the outcome of a ruptured
berry aneurysm? The insert image
shows changes of atherosclerosis. Note the cholesterol slits in the fragmented
plaque. |
