Reversible cerebral vasoconstriction syndrome
Internal Medicine Journal, 2015AbstractReversible cerebral vasoconstriction syndrome (RCVS) is a clinical‐radiological syndrome characterised by severe thunderclap headaches with or without other neurological symptoms and multifocal constriction of cerebral arteries that usually resolves spontaneously within 3 months.

Cold vasoconstriction and vasodilatation
The Irish Journal of Medical Science, 19511. When the finger is immersed in water between 0° and 6°C. the initial vasoconstriction is usually, and the subsequent vasoconstrictions are occasionally, sudden in onset and complete in degree. 2. The initial vasodilatation is usually rapid in onset. 3.

Reversible cerebral vasoconstriction syndrome
Neuropsychological Rehabilitation, 2016Reversible cerebral vasoconstriction syndrome (RCVS) is a relatively rare, non-progressive angiopathy frequently heralded by severe thunderclap headache. It is characterised by vasoconstriction of cerebral arteries which usually resolves within three months of onset.

Reversible Cerebral Vasoconstriction Syndrome
JAMA Neurology, 2014Sneddon's syndrome (SS) refers to an infrequent disorder combining skin and ischemic cerebral lesions in patients without a recognizable connective tissue or inflammatory or chronic infectious disease. As a rule, the transient ischemic attacks and strokes are multiple and recurrent in the same or different vascular territories.

Cerebral vasoconstriction in toxemia
Neurology, 1987Three patients with toxemia developed acute neurologic deterioration postpartum. In all, cerebral angiography revealed widespread arterial vasoconstriction. Cerebral vasoconstriction may be an important cause of neurologic complications in toxemia.

Reversible Cerebral Vasoconstriction Syndromes
2016Reversible cerebral vasoconstriction syndrome (RCVS) is a term used to describe a group of conditions characterized by reversible segmental narrowing and dilatation of multiple intracranial arteries. Most patients present with an explosive-onset, severe (thunderclap) headache. Thunderclap headaches frequently recur over days to weeks.

Cryoprotective properties of vasoconstriction
Cryobiology, 1974Abstract In standardized freezing experiments made on depilated rat skin, it was found that vasconstriction gives some cryoprotection, but, only if tissue temperatures do not drop below −30 °C. It is suggested that vasoconstriction, which is a well-known sequel to more moderate drops in tissue temperature, is in fact a physiological temperature ...

Various Vagaries of Vasoconstriction
Archives of Dermatology, 1974The standard vasoconstrictor assay has been of proven value in ranking the potencies of topically applied corticosteroids from alcoholic solutions. Shortening the time of application, omitting occlusion, and using multiple reading times has allowed valuable observations to be made on the effective delivery of corticosteroids from their vehicles.

Reversible cerebral vasoconstriction syndromes
Current Treatment Options in Cardiovascular Medicine, 2006Reversible cerebral vasoconstriction syndromes (RCVS) comprise a set of conditions having in common the apoplectic onset of headache mimicking subarachnoid hemorrhage, focal or multifocal neurologic deficits with a predilection for visual processing disorders, multifocal vasoconstriction on cerebral angiography, noninflammatory spinal fluid, and a ...
