Cerebral arterial fenestration
Computerized Radiology, 1987Fenestration or duplication of a cerebral vessel is a rare congenital variation which most commonly involves the vertebral artery and is usually of no clinical significance. Fenestrations may have associated aneurysms remote to the anomaly or involving the proximal bifurcation of the fenestration.

Anterior Cerebral Artery-Radial Artery-Anterior Cerebral Artery Bypass
2021For a complex intracranial aneurysm originating from the A2 and beyond, in situ side-to-side bypass may be sufficient for cerebral revascularization with aneurysm trapping. Reanastomosis and reimplantation may also be considered alternative treatment modalities. However, in some specific cases with contradictions to all abovementioned bypass techniques,

THE ROLE of vasomotor nerve fibers in the regulation of the caliber of intracranial arteries remains an important clinical and experimental problem. Numerous clinical reports have attested to the benefits of cervical sympathectomy by surgical or chemical means in the treatment of demonstrable or presumed cerebral circulatory disorders.

Anterior Cerebral Artery-Anterior Cerebral Artery Bypass
2021The anterior cerebral artery (ACA) can be defined as two main parts by the anterior communicating artery (ACoA): the horizontal part/the precommunicating segment and the vertical part/the postcommunicating segment. The bilateral ACAs run in parallel in the interhemispheric fissure beyond the ACoA, providing the advantage of an intracranial (IC)-IC ...

Summary Report is made of the investigation of a patient suspected of having a vascular lesion in the posterior fossa. Pneumo-encephalographic and angiographic studies showed this to be an ectatic basilar artery with ‘berry’ aneurysm formation at its bifurcation deforming the floor of the third ventricle.

Middle Cerebral Artery-Middle Cerebral Artery Bypass
2021In this in situ bypass technique, a side-to-side anastomosis of the arteries distal and adjacent to the aneurysm is achieved. The advantages of this method include avoiding the radial artery as the donor artery and subsequent cervical incision, achieving complete restoration of the skull bone flap, and obtaining a similar diameter between the donor and

Posterior Cerebral Artery-Posterior Cerebral Artery Bypass
2021Reconstruction of posterior cerebral artery (PCA) could be performed with superficial temporal artery-PCA (STA-PCA) bypass, in situ PCA-superior cerebellar artery (PCA-SCA) bypass, or P2-P2 reanastomosis. The PCA and SCA are anatomically parallel; however, the PCA caliber is typically double that of the SCA, which limits the utility of PCA-SCA bypass ...

Anterior cerebral artery reconstruction
Neurosurgery, 1986Abstract Anterior cerebral artery end-to-end, end-to-side, and side-to-side anastomoses and grafting procedures including bypass and interposition using segments of the posterior cerebral artery harvested from the same specimen were performed.

Middle Cerebral Artery Dissection
Neuropediatrics, 1996A 12-year-old girl had minor head trauma, with resultant mild headache, one day prior to onset of an apparently generalized tonic clonic seizure, right hemiparesis and dysphasia. A cranial CT scan showed evidence of a left middle cerebral artery infarct.

Posterior cerebral artery stenosis
Annals of Neurology, 1987AbstractWe analyzed the clinical features of symptomatic posterior cerebral artery (PCA) stenosis in 6 patients selected from 15 patients with angiographically documented PCA atherostenosis occurring during a 7‐year period. Transient ischemic attacks (TIAs) were the major presentation in 5 patients.
