Cerebral hyperperfusion syndrome
Cerebral hyperperfusion syndrome is a rare complication described after:
a) Carotid endarterectomy
b) Carotid angioplasty
c) All of the above
d) None of the above
Correct answer: c) All of the above
Ipsilateral headache, nausea, vomiting, focal seizures and altered mental status are the features of cerebral hyperperfusion syndrome. Long standing hypoperfusion due to severe carotid stenosis impairs the cerebral autoregulation of microcirculation. Sudden improvement of perfusion pressure after revascularization overwhelms the ability of dilated arterioles to constrict causing the hyperperfusion syndrome.
