Thrombosis of the Azygos Anterior Cerebral Artery

Case Reports in Radiology, 2017
The azygos anterior cerebral artery is a rare variant, characterized by the absence of the anterior communicating artery and the union of two proximal segments of the anterior cerebral artery, forming a single trunk and ascending through the ...

Bilateral vertebral artery dissection extending to the left posterior cerebral artery: A case report

Radiology Case Reports, 2023
Intracranial artery dissection accounts for a small percentage (1%-2%) of all ischemic strokes. Vertebral artery dissection sometimes extends to the basilar artery but very rarely to the posterior cerebral artery.

Four simultaneous anterior cerebral artery aneurysms (three initially unsuspected) with surgical treatment

Radiology Case Reports, 2019
Distal anterior cerebral artery aneurysms are rare, comprising approximately 6% of all intracranial aneurysms. These aneurysms tend to be smaller in size, broad-based, associated with additional aneurysms and at arterial branching sites, which can make ...

The slope of cerebral oxyhemoglobin oscillation is associated with vascular reserve capacity in large artery steno-occlusion

Scientific Reports, 2021
Inadequate cerebral perfusion is a risk factor for cerebral ischemia in patients with large artery steno-occlusion. We investigated whether prefrontal oxyhemoglobin oscillation (ΔHbO2, 0.6–2 Hz) was associated with decreased vascular reserve in patients ...

Clinical Characteristics and Outcome of Patients with Distal Anterior Cerebral Artery Aneurysms

Journal of Nepal Health Research Council
Background: Distal anterior cerebral artery aneurysms account for 3% to 7% of intracranial aneurysms. They have increased risk of premature rupture during surgery and tend to have a higher morbidity.

Distal anterior cerebral artery aneurysm with bilateral fetal posterior cerebral arteries and trifurcation of anterior cerebral artery

Indian Journal of Pathology and Microbiology, 2020
Developmental vascular anomalies of brain are non-modifiable risk factors for the development of aneurysms and are prone for rupture. We report one such association in a 44–year-old gentleman who succumbed to subarachnoid hemorrhage (SAH) secondary to ...

Multiple cerebral fusiform aneurysms involving the posterior and anterior circulation including the anterior cerebral artery: a case report

Folia Neuropathologica, 2017
Multiple fusiform aneurysms occurring in a single patient are very uncommon. Fusiform aneurysms affecting the anterior circulation are extremely rare and reported cases involve the middle cerebral artery and internal carotid artery. We report here a case

Management of Ruptured and Rapidly Progressive Mycotic Cerebral Aneurysms in the Setting of Unilateral Carotid Occlusion and Endocarditis with Valve Failure

Journal of Neurological Surgery Reports, 2015
Mycotic cerebral aneurysms can present unique neurosurgical challenges. We report a patient with left carotid occlusions, a ruptured left middle cerebral artery mycotic aneurysm, and a rapidly appearing unruptured left anterior cerebral artery/anterior ...
