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 ...

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.

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.

Morphology of cerebral arteries
Pharmacology & Therapeutics, 1995A comparison of the major cerebral arteries between humans and rats shows many similarities, including anomalies in their general organization, the structure of these vessels at the light and electron microscope levels and their morphological changes associated with cerebral vascular diseases.

Fenestration of the middle cerebral artery
Neuroradiology, 1977Three cases of angiographically demonstrated fenestration of the middle cerebral artery are reported. The incidence of demonstration of fenestration of the middle cerebral artery by angiography is 0.26%. Its clinical significance is discussed briefly.

Duplicated middle cerebral artery (DMCA) has been reported in 0.7%-2.9% of autopsy cases, and sme reports have described aneurysms in the MCA. Both ruptured and unruptured aneurysms in the MCA have been reported, often requiring surgical intervention. During surgery for aneurysm in DMCA, care must be taken to avoid damaging the MCA, which supplies the ...

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.

Cerebral Artery Bypass Surgery
AJN, American Journal of Nursing, 1980commonly caused by atherosclerosis of the cerebral arteries(l,2). Atherosclerosis, a form of arteriosclerosis, is an accumulation of lipid plaques in the intima of an artery. These plaques interrupt blood flow by narrowing the vessels and, in severe cases, totally occlude the artery.

Middle Cerebral Artery Fenestration
Neurosurgery, 1980Fenestration of the middle cerebral artery (MCA) is an unusual anomaly. We recognized and photographed MCA fenestration during an operation performed to clip an internal carotid artery aneurysm. The incidence of angiographic demonstration of this anomaly has been reported to be 0.26%.

The anterior cerebral artery (ACA) arises as a branch of the primitive olfactory artery which originates from the anterior cranial division of the ICA. The ACA develops replacing progressively the primitive olfactory artery which regresses. Later in the evolution from the ACA arises as a secondary branch the MCA (De Vriese 1905; Abbie 1934; Padget 1948;
