Migraine surgery is any surgical operation undertaken with the goal of reducing or preventing migraines. It is considered by some as an alternative when other treatments are not effective. The American Headache Society has advised that no physician recommend surgical deactivation of migraine trigger points outside of experimental clinical trials because no accurate estimates exist about the efficacy and harms of the surgery.
Migraine surgery involving deactivation of migraine trigger points is not indicated outside of experimental clinical trials because no accurate estimates exist about the efficacy and harms of the surgery. While some observational studies have suggested possible benefit, the amount of available evidence on migraine surgery does not provide accurate estimates of the surgery's efficacy or describe the harms it causes. Long-term side effects are unknown and could be problematic. The American Headache Society and others urge caution about this procedure.
Patent foramen ovale closure
It is unclear if an open patent foramen ovale is or is not related to migraines with an aura. Data supporting an effect of closure on the rates of migraines is mostly of low quality. The only randomized trial did not find benefit.
