The effect of percutaneous closure of patent foramen ovales on migraine headaches.

摘要

Problem: Approximately 10% of the general population suffers from migraine headaches. Without a clear causation for these headaches, treatment can be difficult. Recently there have been theories connecting migraines to patent foramen ovales (PFO) and discussion on whether closing the PFO is a plausible treatment for the headaches.;Results: The results showed that there may be a benefit to closing PFOs to treat migraine headaches. All studies showed at least 50% of patients were either cured or had a significant improvement of their migraine headaches.;Conclusion: There is potential in using closure of PFOs as a treatment option for patients refractory to medical treatment. However, a large case control prospective study has yet to be performed.;Methods: A search was conducted using the Weill Cornell Library online database. Original studies conducted on the effect of PFO closure on migraine headaches in the last ten years were used.
