Description:
Headache caused directly by cerebral angiography.
Diagnostic criteria:
- Any new headache fulfilling criterion C
- Intra-arterial carotid or vertebral angiography has been performed
- Evidence of causation demonstrated by at least two of the following:
- headache has developed during or within 24 hours of the angiography
- headache has resolved within 72 hours after the angiography
- headache has one of the following sets of characteristics1:
- a) developing during contrast injection and lasting <1 hour
- b) developing a few hours after the angiography and lasting >24 hours
- c) occurring in a patient with 1. Migraine and having the features of 1.1 Migraine without aura or 1.2 Migraine with aura
- Not better accounted for by another ICHD-3 diagnosis.
Note:
There are three recognized (but not separately coded) subforms of 6.7.2 Angiography headache.
- occurring during angiography, and closely related to contrast injection;
- occurring later, but within 24 hours;
(both these subforms are more common in patients with a history of primary headache, but are distinctly different in character from the primary headache);
Comment:
Contrast angiography is contraindicated in patients affected by any subform of 1.2.3 Hemiplegic migraine because it may trigger a life-threatening attack, with prolonged hemiplegia and coma.
