Dynamics of a haemodynamic headache: A case report and literature review of headache secondary to flow inversion of the internal jugular vein
Conclusions
The case of our patient suggests that unilateral, episodic, non-throbbing, non-postural headache with transient neurological symptoms can be caused by combined arterial and venous flow abnormalities secondary to a high-flow arteriovenous brachial fistula. In this setting, this pattern of headache may precede overt signs of intracranial hypertension and may be used as a warning sign of cerebral venous congestion.
