چکیده

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 treatment of the aneurysm at the proximal ACA or anterior communicating artery (ACoA) may sometimes be difficult, because the veiled proximal ACA by the optic nerve would make proximal control inconvenient and the vertical midline segment of the proximal ACA would frequently form a superiorly directing aneurysm with a relatively high position. We report on an extremely rare case of a ruptured aneurysm at the infraoptic azygous ACA, possibly having an extradural origin, accompanied by contralateral ICA agenesis, and also introduce a feasible method for treatment by Y-stent assisted coil embolization.

Dual diagnostic catheter technique in the endovascular management of anterior communicating artery complex aneurysms

BACKGROUND The configuration of the anterior communicating artery (AcomA) complex is important in the endovascular treatment of AcomA complex aneurysms. In cases of codominant anterior cerebral arteries (ACA), coil embolization may result in inadvertent occlusion of the contralateral ACA due to poor visualization. A second diagnostic catheter in the contralateral carotid artery may help with vi...

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...

A case of anterior communicating artery aneurysm successfully treated after a stent migration during stent assisted endovascular coil embolization

Stent migration is a complication associated with endovascular coil embolization of intracranial aneurysms. We report a case of anterior communicating artery (ACoA) aneurysm that was successfully treated after stent migration during endovascular coil embolization without retrieval of the stent. A 47-year-old man presented with sudden onset severe headache. Patient was noted to have subarachnoid...
