Table 14 Recommended diagnostic criteria for angiography headache

Section 6.7.2: Angiography headache
Description: Headache caused directly by cerebral angiography.
Diagnostic criteria:
A. Any new headache fulfilling criterion C
B. Intra-arterial carotid or vertebral angiography has been performed
C. Evidence of causation demonstrated by at least two of the following:
1. headache has developed during the angiography
2. headache has developed after the angiography and within 7 days
3. headache has two of the following sets of characteristics¹:
a) developing during contrast injection and lasting <1 hour
b) developing within 7 days after angiography and a single headache lasting < 24 hours
c) with pain mostly associated with mild-moderate, throbbing or pressing pain with photophobia, nausea and no vomiting
D. Not better accounted for by another ICHD-3 diagnosis.

1There are three recognized (but not separately coded) subforms of 6.7.2 Angiography headache
a) occurring during angiography, and closely related to contrast injection
b) occurring later, but within 7days (both these subforms are more common in patients with a history of primary headache, but are distinctly different in character from the primary headache and about one-third of patients may have more than one headache attack)
c) a migraine attack, occurring in a person who has 1. Migraine and triggered by angiography (in these cases, the patient should have both diagnoses: the appropriate type or subtype of 1. Migraine and 6.7.2 Angiography headache)
