Significats de cerebral vasoconstriction en anglès

Sympathetic stimulation is reported to cause cerebral vasoconstriction and reduce CBF in animals.

No headache or neurologic deficit was noted in all 10 patients with cerebral vasoconstriction.

Hypocapnic cerebral vasoconstriction is well described and causes an immediate and profound decrease in cerebral perfusion.

A large-scale study is necessary to assess the clinical implications of cerebral vasoconstriction after carotid artery stenting.

Aim: In patients with thunderclap headaches, reversible cerebral vasoconstriction syndrome (RCVS) should be considered as a differential diagnosis.

Conclusion: Reversible cerebral vasoconstriction syndrome with negative CT findings at the ED visit was likely to be misdiagnosed as a primary headache.

This seems to have an important role in the enhanced cerebral vasoconstriction in the delayed post-ischaemic hypoperfusion phase after experimental forebrain ischaemia.

Endovascular options for patients with refractory reversible cerebral vasoconstriction syndrome include intra-arterial vasodilator infusion similar to therapy for patients with vasospasm after SAH.

To date, only case reports and 1 small series have discussed the utility of intra-arterial vasodilators for the treatment of reversible cerebral vasoconstriction syndrome.

We report an additional series of 11 medically refractory cases of presumed or proved reversible cerebral vasoconstriction syndrome successfully treated with intra-arterial verapamil infusion.

Conclusions: Cerebral vasoconstriction may occur after carotid artery stenting more frequently than expected.
