Suzuki, "Anterior communicating artery
aneurysms with associated anomalies," Journal of Neurosurgery, vol.
of California, San Francisco) details the basic concepts and tenets of aneurysm microsurgery, various craniotomies and exposures for successful clipping, and microsurgical anatomy, dissection strategies, and clipping techniques for each of the seven most common aneurysm types: posterior and anterior communicating artery
, middle cerebral artery, ophthalmic artery, basilar bifurcation, pericallosal artery, and posterior inferior cerebellar artery aneurysms.

The primary routes of collateral circulation are the Willisian channels (anterior communicating artery
, posterior communicating artery, and the ophthalmic via the external carotid artery).
The patient presented with subarachnoid hemorrhage caused by an aneurysm of the anterior communicating artery
. He underwent surgical clipping and developed cerebral ischemia due to vasospasm.
When location was examined as a risk factor, only aneurysms in the anterior communicating artery
(ACoA) and posterior communicating artery (PCoA) were significantly more likely to be found among patients with ruptured aneurysms.
Left anterior and middle cerebral arterial flow was maintained through the anterior communicating artery
. The vertebral arteries and the right internal and external carotid arteries were patent and normal.
