Upon autopsy of a 25-year-old, abnormalities in the media of the arterial wall and degenerative changes were detected. Which of the following would most likely accompany this finding?
a. Fusiform aneurysm
b. Saccular aneurysm
c. Arteriovenous malformation
d. Thrombotic stroke
ANS: B
Saccular aneurysms (berry aneurysms) occur frequently (in approximately 2% of the population) and likely result from congenital abnormalities in the media of the arterial wall and degenerative changes. Fusiform aneurysms (giant aneurysms) occur as a result of diffuse arteriosclerotic changes and are found most commonly in the basilar arteries or terminal portions of the internal carotid arteries. Arteriovenous malformation (AVM) is a tangled mass of dilated blood vessels creating abnormal channels between the arterial and venous systems. Thrombotic stroke would show signs of necrotic tissue, not degenerative changes.
