vasospasm

 [vas´o-spazm]
a spasm of blood vessels, causing vasoconstriction; called also angiospasm. adj., adj vasospas´tic.

Contraction or hypertonia of the muscular coats of the blood vessels.

vasospasm

(vā′zō-spăz′əm)
n.
A sudden constriction of a blood vessel, causing a reduction in blood flow.

va′so·spas′tic (-spăs′tĭk) adj.

vasospasm

An abrupt and/or excess local or regional contraction of vascular smooth muscle; vasospasm may underlying amaurosis fugax, thrombosis-negative MI, migraine, Prinzmetal's angina, Raynaud's phenomenon, subarachnoid hematoma-related CVAs

Contraction or hypertonia of the muscular coats of the blood vessels.
Synonym(s): angiospasm.

vasospasm

Tightening or spasm of blood vessels.

Vasospasm

The constriction or narrowing of blood vessels. In cases of hemorrhage, the constriction is prompted by chemical signals from the escaped blood as it breaks down.

* A hypocalcaemia-induced acute coronary syndrome is most likely a function of the myocardium being perfused primarily during diastole, with partial vasospasm limiting the diastolic flow during times of increased cardiac output or energy requirements.
The incidences of complications including hydrocephalus, vasospasm, subarachnoid hemorrhage and aneurysm rupture of the observation group were lower than those of the control group, and the differences were statistically significant (P<0.05), which was similar to the research results of Xue MJ.
Although these studies found a very low incidence of adverse events associated with early mobilisation, patients demonstrating a deterioration in neurological status or signs of vasospasm on screening were not mobilised.
In patients with neurological deterioration and/or cerebral vasospasm after aneurysm repair, systolic BP was targeted at greater than 160 mm Hg or a minimum of 20 mm Hg higher than average for stay.
(6) IV administration, in particular IV bolus administration, rapid IV infusion, or failure to administer the guide dose titration results in coronary vasospasm, myocardial ischemia, transient left ventricular dysfunction, and pulmonary edema.
Acute catecholamine surgemediated vasospasm can be postulated as the cause of STEMI in this patient.
We report the case of a patient with severe thyrotoxicosis who presented with a spectrum of cardiovascular complications of fast atrial fibrillation and congestive cardiac failure who developed silent acute myocardial infarction as a consequence of severe diffuse coronary artery vasospasm.
When faced with symptoms compatible with vasospasm or nonocclusive arterial ischemia and in absence of any thrombophilic pathology or arteritides, thorough interview and physical examination are important to find clues to this rare disorder.
The major drawback of these devices is the small sampling volume, which precludes robust assessment of early changes potentially leading to vasospasm. Choosing a target has been done through standardized landmarks and insertion angles of a monitoring "bundle" in either frontal lobe depending on the seen or sometimes perceived burden of pathology.

First of all, clomipramine-induced vasospasm was considered as a potential cause of symptoms.
The lowest positive correlation for glaucoma development was determined in patients with systemic hypertension (3%) (10,11), patients with migraine headaches and vasospasm and hypotension episodes.
