An Unruptured Anterior Communicating Artery Aneurysm with Bilateral Infraoptic Anterior Cerebral Arteries. Case Report and Review of the Literature
نویسندگان
چکیده
Variations of the anterior cerebral artery-anterior communicating artery complex are commonly identified in aneurysm surgery. An infraoptic course of the anterior cerebral artery is exceedingly rare. Robison first described this anomaly from an anatomic dissection in 1959. A unilateral anomalous infraoptic anterior cerebral artery is more common than anomalies of bilateral infraoptic anterior cerebral arteries. We present the case of an unruptured aneurysm at the anterior communicating artery in a patient with bilateral infraoptic anterior cerebral arteries, identified by computed tomography angiography and verified during surgery. Implications for aneurysm formation and surgical treatment are discussed.

Infraoptic Course of the Anterior Cerebral Artery: Case Report
(ACA)-anterior communicating artery (AComA) complex are commonly identified at imaging studies, an infraoptic ACA is extremely rare (1-4). In such cases, an anomalous vessel originates from the internal carotid artery (ICA) at the level of the ophthalmic artery, and then pursues an infraoptic and prechiasmatic path to supply the ACA. We describe a case of in which this anomaly coexisted with a ...

Infraoptic anterior cerebral artery (ACA) is an extremely rare congenital anomaly. This anomalous artery usually arises from the intradural internal carotid artery (ICA) near the level of the ophthalmic artery (OA) or rarely from the extradural ICA. This anomaly frequently harbors a cerebral aneurysm, and may involve other coexisting vascular anomalies. In the case of this anomaly, surgical tre...
متن کاملRecognition and importance of an infraoptic anterior cerebral artery: case report.
Although variations of the anterior cerebral artery (ACA)-anterior communicating artery complex are commonly identified on imaging studies, an infraoptic course of the ACA is exceedingly rare. What is believed to be the first case of an infraoptic course of the ACA discovered with MR angiography and further characterized with conventional angiography is presented. The high prevalence of associa...
متن کاملA Rare Embryologic Variation: Anterior Communicating Artery Aneurysm Associated with Carotid—Anterior Cerebral Artery Anastomosis or Infraoptic Course of the Anterior Cerebral Artery
Aneurysms of the complex of the anterior cerebral artery are frequently associated with anatomic variations of the circle of Willis. We describe a case of aneurysmal rupture of the anterior communicating artery, a variant of the anterior cerebral artery. The aneurysm appeared to be situated on this vessel proximal to the infered site of the AcoA. Surgery was performed at the 6th day after hemor...
