Dissecting Aneurysm at the Proximal Segment of the Anterior Cerebral Artery Associated with Infraoptic Course Anterior Cerebral Artery
A 48-year-old man presented a subarachnoid hemorrhage caused by a rupture of a dissecting aneurysm at the proximal segment (A1 segment) of the right anterior cerebral artery (ACA). He also had an anomalous artery named infraoptic course ACA and an agenesis of the contralateral ACA A1 segment. Balloon occlusion test at the bifurcation of the right internal carotid artery demonstrated that the di...
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...
متن کاملInfraoptic 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 ...
متن کاملBilateral anomalous anterior cerebral artery and infraoptic aneurysm.
A CT scan demonstrated a subarachnoid hemorrhage. A followup four-vessel cerebral angiogram demonstrated bilateral anomalous ACAs, with the origin at the level of the ophthalmic artery proximal to the posterior communicating and anterior choroidal arteries. The proximal portion of each ectopic proximal segment was horizontal , suggesting that both ACAs coursed below the optic nerves (Figs . 1 A...
متن کاملAzygos anterior cerebral artery aneurysm associated with fenestration of the anterior cerebral artery.
Azygos ACA (Alpers et al. 1959; Bap tista et al. 1963; Pool et al. 1965), triple ACA (Baptista et al. 1963) and A1 fenestration (A1 pers et al. 1959; Crompton, 1962; Baptista et al. 1963; Teal et al. 1973; Ito et al. 1981; Krayenbuhl et al . 1982) are known as anomalies related to the anterior cerebral artery (ACA). Each of them is a rare vascular anomaly, and only a few reports have been prese...
