Fenestration of the middle cerebral artery

Neuroradiology, 1977
Three 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.

Posterior Cerebral Artery-Posterior Cerebral Artery Bypass

2021
Reconstruction 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 ...

Morphology of cerebral arteries

Pharmacology & Therapeutics, 1995
A 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.

Anterior cerebral artery reconstruction

Neurosurgery, 1986
Abstract 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.

Unruptured Middle Cerebral Artery Aneurysm Associated With a Duplicated Middle Cerebral Artery and a Dolichoectasic Anterior Cerebral Artery

Journal of Stroke and Cerebrovascular Diseases, 2010
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 ...

Cerebral Autoregulation in Middle Cerebral Artery Territory Precedes That of Posterior Cerebral Artery in Human Cortex

Cerebrovascular Diseases, 2002
<i>Objective:</i> Cerebral autoregulation tends to compensate changes in arterial blood pressure. This mechanism of cerebral blood flow regulation appears to be insufficient in orthostatic dysregulation in which mainly vertebrobasilar symptoms occur.

Microanatomy of the anterior cerebral artery

Surgical Neurology, 1986
The microanatomic features of the anterior cerebral artery were studied in 30 unfixed human brains which were injected with tinted polyester resin via cannulation of the internal carotid arteries under microscopic dissection. The outer diameter, length, and number of perforating branches were measured for each of the following vessels: anterior ...

Dissection of Cervical and Cerebral Arteries

Current Neurology and Neuroscience Reports, 2017
We aimed to summarize recent findings in cervical (CeAD) and intracranial artery dissection (IAD) research.Considered a disease of the young- and middle-aged, an analysis on the largest CeAD-population to date (n = 2391) revealed that about 1 of 14 CeAD-patients was aged ≥60 years. Distinct genetic variants were associated with CeAD.

Middle Cerebral Artery Dissection

Neuropediatrics, 1996
A 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, 1987
AbstractWe 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.
