Vasospasm is common post subarachnoid hemorrhage and cerebral aneurysm, but in RCVS only 25 % of patients have symptoms post subarachnoid hemorrhage.

People with subarachnoid hemorrhage, a blown pupil, respiratory distress, hypotension, or cerebral vasospasm are more likely to have worse outcomes.
13.
Phenylalkylamine calcium channel blockers are relatively selective for myocardium, reduce myocardial oxygen demand and reverse coronary vasospasm, and are often used to treat angina.
14.
Events reported have included coronary artery vasospasm, transient myocardial ischemia, myocardial infarction, ventricular tachycardia, and ventricular fibrillation ( V-Fib ).
15.
Studies with PET scanning and transcranial Doppler imaging have shown that changes in cerebral blood flow, such as hypoperfusion and vasospasm, can follow penetrating head injury.
16.
Ergotamine / dihydroergotamine : Concurrent use of erythromycin and ergotamine or dihydroergotamine has been associated in some patients with acute ergot toxicity characterized by severe peripheral vasospasm and dysesthesia.
17.
Following a study and publication in 2007, it is also thought SSRIs, uncontrolled hypertension, endocrine abnormality, and neurosurgical trauma are indicated to potentially cause vasospasm.
18.
Rebleeding, hydrocephalus ( the excessive accumulation of cerebrospinal fluid ), vasospasm ( spasm, or narrowing, of the blood vessels ), or multiple aneurysms may also occur.
19.
In patients with aneurysmal subarachnoid hemorrhage the EVD is used to remove cerebrospinal fluid, blood, and blood byproducts that increase intracranial pressure and may increase the risk for cerebral vasospasm.
20.
Fasudil has been used to characterize the role of ROCK1 in vascular function in clinical studies and has been approved for use in Japan for treatment of cerebral vasospasm following subarachnoid hemorrhage.
