===== Definition =====

An [[anterior communicating artery]] aneurysm is a [[intracranial aneurysm]] localized, abnormal dilation or ballooning of the anterior communicating artery.

===== Epidemiology =====

===== Clinical features =====
see [[Anterior communicating artery aneurysm clinical features]].




===== Diagnosis =====

[[Anterior communicating artery aneurysm diagnosis]].

===== Management =====

The [[management]] of an anterior communicating artery (ACoA) aneurysm involves a multidisciplinary approach and may include medical, endovascular, or surgical interventions. The specific treatment plan depends on various factors, including the size and location of the aneurysm, the patient's overall health, and the presence of any symptoms.

==== Q11597 ====

A 44-year-old patient arrives at the [[Emergency Department]] brought in by the Emergency Medical Service ([[SAMU]]) following a deterioration in the level of [[consciousness]] at home. Apparently, they were found at the foot of the bed with [[sphincter]] relaxation. Their companions (not present during the examination) were able to lift them onto the bed, and SAMU was called. On assessment, the patient has a [[Glasgow Coma Scale]] (GCS) score of 13, along with hypertensive crisis, and is brought in receiving [[Urapidil]] 50 mg + 50 mg in infusion.

Vital signs:

Blood pressure: 190/98 mmHg
Heart rate: 80 beats per minute
Oxygen saturation (SpO2): 98% (ambient air)
Neurological examination according to the Glasgow Coma Scale:

Eye opening (E): 2
Verbal response (V): 2
Motor response (M): 5
Total score: 9

Extensive [[subarachnoid hemorrhage]] distributed throughout [[perimesencephalic cistern]]s (predominantly in the [[chiasmatic cistern]]), [[prepontine cistern]], both [[Sylvian fissure]]s, and [[interhemispheric fissure]], with a component of bifrontal parasagittal [[intraparenchymal hematoma]] with mild adjacent [[vasogenic edema]]. The hemorrhage also extends into the [[ventricular system]] ([[third ventricle]] and [[lateral ventricle]]s). Findings consistent with modified Fisher grade IV subarachnoid hemorrhage.

This extension is compatible with an [[aneurysmal subarachnoid hemorrhage]] pattern.

Erasure of cerebral [[sulci]], predominantly frontotemporal, in relation to diffuse [[cerebral edema]].

Increased ventricular size for the patient's age.
