How is reversible cerebral vasoconstriction syndrome diagnosed?
The diagnosis of RCVS is based on a person’s medical history, symptoms, a complete physical exam, and the results of vascular brain imaging. Such imaging may be in the form of an angiogram, MRA, or CTA scan that can show spasms in blood vessels that are narrowed.
What is reversible cerebral vasoconstriction syndrome?
Reversible cerebral vasoconstriction syndrome (RCVS) is a group of disorders characterized by severe headaches and a narrowing of the blood vessels in the brain. RCVS is reversible and patients often recover within three months; the condition is frequently missed and is more common than most physicians realize.
Is RCVS life threatening?
Background: A fatal outcome occurs in 2% of patients with Reversible Cerebral Vasoconstriction Syndrome (RCVS). Due to its rarity, guidelines for the management of the most severe forms of RCVS are lacking.
Can RCVS recur?
The main result is that RCVS can hit twice. Recurrence occurred in a minority of cases (9 of the 168 patients, 5%) with a delay from the first to the second bout ranging from 6 months to 7 years. All initial RCVS were idiopathic. Recurrent RCVS was idiopathic in 8 cases and triggered by a vasoactive drug in one.
Is RCVS a brain injury?
In one report of 139 patients with RCVS, a majority (81 percent) eventually developed brain lesions including ischemic infarction (39 percent), brain edema (38 percent), convexity subarachnoid hemorrhage (33 percent), and lobar hemorrhage (20 percent) .
Can I exercise with RCVS?
Recurrence of an episode of RCVS is extremely rare. Most people can resume routine physical activities and gradually increase the intensity of exercise two to four weeks after the sudden-onset headaches subside.
Can you exercise with RCVS?
How do you fix vasoconstriction?
Vasoconstriction (muscles tightening your blood vessels to shrink the space inside) is something your body needs to do sometimes….What can I do at home to treat vasoconstriction?
- Bring down your stress level.
- Avoid caffeine.
- Exercise (and do a warm-up for a few minutes first).
- Stop smoking.
Can you fly with RCVS?
Patients with RCVS typically report at least one trigger (3). If airplane travel (especially at landing) is a possible trigger of RCVS as in our case, the possibility that RCVS recurs at multiple flight conditions cannot be excluded.
What triggers vasoconstriction?
Normally, the vessels that supply blood to the skin constrict or narrow in response to cold temperatures. This reaction, called “vasoconstriction,” decreases blood flow to the skin, which helps to minimize heat loss from the warm blood and therefore preserve a normal internal or “core” temperature.
Does aspirin help vasoconstriction?
The present studies indicate that salicylates, including aspirin and sodium salicylate, relax vasoconstriction through inhibiting PYK2-mediated RhoA/Rho-kinase activation, offering a mechanistic insight into the unique blood pressure effect of salicylates.
How do you reverse vasoconstriction?
Reversible cerebral vasoconstriction syndrome. Reversible cerebral vasoconstriction syndrome (RCVS) is a group of conditions with a common clinical and radiologic presentation. It is characterized by thunderclap headache and reversible vasoconstriction of the cerebral arteries.

Which imaging studies are used in the workup of cerebral vasoconstriction syndrome?
High-resolution MRI vessel wall imaging: spatial and temporal patterns of reversible cerebral vasoconstriction syndrome and central nervous system vasculitis. AJNR Am J Neuroradiol 2014;35:1527–32
Which genes are involved in reversible vasoconstriction syndrome?
