6.7.1 Headache attributed to an intracranial endarterial procedureHartmut Gobel2018-02-06T10:46:18+00:00
Description:
Unilateral headache caused directly by an intracranial endarterial procedure, ipsilateral to the procedure and lasting less than 24 hours.
Diagnostic criteria:
- Any new headache fulfilling criterion C
- An intracranial endarterial procedure has been performed1
- Evidence of causation demonstrated by at least three of the following:
- headache has developed within 1 week of the procedure
- headache has resolved within 1 month after the procedure
- headache is ipsilateral to the procedure, or bilateral
- headache has one of the following sets of characteristics2:
- a) severe, occurring abruptly within seconds of the procedure and lasting <1 hour
- b) moderate to severe, developing within hours of the procedure 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 diagnosis3.
Notes:
- For example, angioplasty, embolization or stent placement.
- There are three recognized (but not separately coded) subforms of 6.7.1 Headache attributed to an intracranial endarterial procedure:
- a) a very specific subform reported after balloon inflation or embolization of an AVM or aneurysm: severe pain localized according to the artery involved, developing abruptly within a few seconds of the procedure, and disappearing rapidly;
- b) headache developing within hours to one day following the procedure and lasting a few days;
- c) a migraine attack, occurring in a person who has 1. Migraine and triggered by the intracranial endarterial procedure; this is sometimes followed by recurrent intermittent headache during several weeks (in these cases, the patient should have both diagnoses: the appropriate type or subtype of 1. Migraine and 6.7.1 Headache attributed to an intracranial endarterial procedure).
- In particular, arterial dissection and arterial rupture have been excluded by appropriate investigations.
