Severe headache in a middle-aged woman after device closure of a ventricular septal defect.

Reversible cerebral vasoconstriction syndrome presents with thunderclap headache and represents a group of conditions that show reversible multifocal narrowing of cerebral arteries. Some patients who undergo device closure of an atrial septal defect complain of headache, which are posited as a migraine. Here we report a case of severe headache due not to migraine but reversible cerebral vasoconstriction syndrome after device closure of a ventricular septal defect.
