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.

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 ...

<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.

Dissection of Cervical and Cerebral Arteries
Current Neurology and Neuroscience Reports, 2017We 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.

Medullary Arteries in Cerebral Neoplasms
Acta Radiologica. Diagnosis, 1975In cerebral neoplasms, the visibility of long segments of the medullary arteries indicates white matter involvement by infiltrative or compressive disturbances. Relating the mass effect to the position of the medullary arteries should allow for differentiating a primary from a secondary avascular neoplasm. When the neoplasm is vascular, the presence of

Microanatomy of the anterior cerebral artery
Surgical Neurology, 1986The 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 ...

Aneurysms of the Posterior Cerebral Artery
Journal of Neurosurgery, 1969NEURYSMS of the posterior cerebral artery are unusual; their surgical treatment demands great care for the central perforating branches of this vessel irrigate the midbrain and thalamus while the main trunk nourishes the optic radiation and visual cortex. Experience has been gained with eight cases of which six were operated on, with one death (Table 1

Accessory middle cerebral artery associated with an accessory anterior cerebral artery
Surgical and Radiologic AnatomyAlthough both accessory middle cerebral artery (MCA) and accessory anterior cerebral artery (ACA) are not rare anatomical variations, their combination is rare and there are only a limited number of reports of such combinations.We report a case of accessory MCA associated with an accessory ACA diagnosed by magnetic resonance angiography (MRA).A 39-year-

Posttraumatic Cerebral Arterial Spasm
Journal of Neurotrauma, 1995Posttraumatic cerebral arterial spasm (vasospasm) has been demonstrated in the past by angiography, and recently by transcranial Doppler ultrasonography. Posttraumatic vasospasm is a delayed complication that involves the large basal intracranial arteries (e.g., internal carotid, middle cerebral, basilar) and occurs in 25-40% of head trauma patient ...
