It is not frequently used for this indication, but has shown good results in preventing a major complication of subarachnoid hemorrhage ( a form of cerebral hemorrhage ) termed vasospasm; this is now the main use of nimodipine.
32.
Various other conditions have been associated with splenic infarction in case reporters, for example granulomatosis with polyangiitis or treatment with drugs that predispose to vasospasm or thrombosis, like vasoconstrictors used to treat esophageal varices, sumatriptan or bevacizumab.
33.
Patients who undergo surgery to repair a ruptured blood vessel after a kind of stroke called a subarachnoid hemorrhage, or SAH, often develop a vasospasm, in which arteries in the head shrink, starving the brain of blood.
34.
It is likely that there are multiple factors at play that could include some amount of vasospasm, failure of the microvasculature, and an abnormal response to catecholamines ( such as epinephrine and norepinephrine, released in response to stress ).
35.
Reactive hyperaemia often occurs as a consequence of Raynaud's phenomenon, where the vasospasm in the vasculature leads to ischaemia and necrosis of tissue and thus a subsequent increase in blood flow to remove the waste products and clear up cell debris.
36.
In 1955, Zaidi travelled back to India to be named Head the Division of Experimental Medicine and then Deputy Director at Central Drug Research Institute ( CDRI ) in Lucknow, where his research focused on mechanisms that underlie peptic ulcer, atherosclerosis, vasospasm, and eosinophilia.
37.
They also dismissed the claim that Eng died of shock and attributed the muscle cramping that caused his testicle to retract to " acrocyanosis from induced vasospasm and microthrombi due to disseminated intravascular coagulation, the tissue factor released from necrotic tissue and the endotoxin from sepsis activating coagulation cascade ".
38.
Rare side effects include flushing of the face, hyperhidrosis ( excessive sweating ), cutaneous eruption, arterial hypotension, tachycardia, loss of appetite, jaundice, eosinophilia, thrombopenia, mixed hepatitis, headache, allergic reaction, chronic active hepatitis, and paradoxical aggravation of cerebral vasospasm.
39.
Neurohydrodynamics investigates the role of intracranial fluid hydrodynamics ( e . g . cerebrospinal fluid, cerebral blood flow, and interstitial fluid ) in the pathophysiology of neurological disorders such as hydrocephalus, Chiari malformation, syringomyelia, pseudotumor cerebri, cerebral vasospasm, Alzheimer's disease, multiple sclerosis and cerebral aneurysm.
40.
The needle should not be too small ( so as not to penetrate tiny structures ), the surgeon should draw back on the syringe ( to ensure not have pierced a vessel ), the lidocaine should not contain epinephrine ( which could cause vasospasm ), and the pressure of the injection must always be controlled.
