The anterior communicating artery is found on the underside of the human brain. Situated just in front of the spinal cord, this blood vessel links the left and right anterior cerebral arteries, which deliver oxygenated blood to the medial or inner aspects of the frontal lobe and upper parietal lobes.
What are the causes of iliac artery aneurysm?
A posterior communicating aneurysm is an out-pouching of the wall of a blood vessel located in the brain. The posterior communicating artery is part of the Circle of Willis, a ring or circle of arteries located at the base of the brain. Ruptured blood vessels caused by aneurysms may cause internal bleeding.
ICD-10 code I60. 2 for Nontraumatic subarachnoid hemorrhage from anterior communicating artery is a medical classification as listed by WHO under the range - Diseases of the circulatory system .
Anterior Communicating Artery Aneurysms. ACoA aneurysms arise within the complex of the two anterior cerebral arteries at their anastomosis via the ACoA. They are ensconced by the anterior cerebral arteries and branches leading to a complex and highly variable dissection (Fig. 67-19).
The anterior communicating artery complex consists of two anterior cerebral arteries (ACA), the anterior communicating artery (ACoA) and the recurrent arteries of Heubner [15, 16, 32].
Anterior communicating artery is especially located in close proximity to optic nerve. Aneurysm arising in this area can produce visual symptoms according to their direction while the size is small. Clinical importance of visual symptoms presented by aneurysmal optic nerve compression is stressed in this study.
The anterior communicating artery connects the one anterior cerebral artery to the other transversely across the longitudinal cerebral fissure. It is located within a small subarachnoid space called the cistern of the lamina terminalis.
The anterior cerebral artery (ACA) arises from the internal carotid at nearly a right angle. It sends deep penetrating branches to supply the most anterior portions of the basal ganglia.
Posterior communicating artery aneurysms (PCAs) are the common site of aneurysms, accounting for about 45.9% of all aneurysms, and have a high rupture rate. Oculomotor nerve palsy (ONP) is a common clinical manifestation of PCAs because of the adjacent anatomical relationship.
Endovascular treatment is an effective method for the treatment of anterior communicating artery aneurysms allowing late rebleeding prevention. Peri-treatment rebleeding warrants caution in anticoagulation management. This is a single center experience and the follow-up period is limited.
The Acom aneurysms at the bifurcation apex mostly deviated toward the smaller angle formed between the parent A1 and branches and toward the daughter artery with a smaller diameter. The Acom aneurysms were located mostly on the dominant anterior cerebral artery.
Anterior cerebral arteries supply blood to the frontal lobes' anterior (front) aspects, areas responsible for higher-level cognition, including judgment and reasoning. Blockages of these arteries can result in cerebral dementia and speech difficulties.

Can people live a long time with a brain aneurysm? Absolutely. Many aneurysms cause no symptoms at all.
About 75% of people with a ruptured brain aneurysm survive longer than 24 hours. A quarter of the survivors, though, may have life-ending complications within six months. Call 911 or go to an emergency room if you think you are having symptoms of a brain aneurysm or ruptured aneurysm.
So, surgery offers the best chance of survival after a rupture. The chance of survival is much better when you have surgery before a rupture. In that case, the chance of surviving aneurysm surgery is 95% to 98%.
