Location of Berry aneurysms

  • Berry aneurysms commonly arise at the bifurcation of major arteries. Approximately 85% of intracranial aneurysms arise on the anterior circulation, mostly on the circle of Willis.
  • Three most common locations are: (Ref.- Harrison 17/e)

– the terminal internal carotid artery

– middle cerebral artery bifurcation

– top of the basilar artery

AIIMS 11

 A

Degeneration of internal elastic lamina

 B

Degeneration of media/muscle cell layer

 C

Deposition of mucoid material in media

 D

Low grade inflammation of vessel wall

Q. 4

Most common site for berry aneurysm rupture

 A

Anterior circulation of brai

 B

Posterior circulation of brain

 C

Ascending aorta

 D

Descending aorta

Q. 4

Most common site for berry aneurysm rupture

 A

Anterior circulation of brai

 B

Posterior circulation of brain

 C

Ascending aorta

 D

Descending aorta

Ans. A

Explanation:

Ans. is ‘a’ i.e., Anterior circulation of brain

The most common sites in descending order of frequency are –

  • Li Proximal portion of anterior communicating artery (at the junction of anterior communicating artery with cerebral artery)
  • At the origin of the posterior communicating artery from the stem of the internal carotid artery.
  • At the first major bifurcation of middle cerebral artery.
  • At the bifurcation of internal carotid into middle and anterior cerebral arteries.
  • Vertibrobasilar bifurcation (3%)

Most common cause of subarachnoid hemorrhage   Trauma
Most common cause of spontaneoussubarachnoid hemorrhage  Rupture of Berry aneurysm

(or Saccular aneurysm)

Also know

Mycotic aneurysm ‑

  • Mycotic aneurysm is caused by a septic embolus that weakens the wall of the vessel in which it lodges.
