Advances in the Study of the Correlation Between Patent Foramen Ovale and Migraine

Abstract
This article examines the relationship between patent foramen ovale (PFO) and migraine, emphasizing the mechanisms underlying the connection and the historical status of transcatheter PFO closure as a treatment for migraine. Patent foramen ovale is the most prevalent congenital cardiac defect in adults and frequently co-occurs with migraine, particularly migraine with aura. This article reviews several studies that have identified a significant prevalence of PFO in patients with migraine, implying that PFO and migraine may be more closely associated than previously thought. The underlying mechanisms of this association involve the transfer of emboli from the venous system to systemic circulation through the PFO, which can result in a range of clinical conditions. Transcatheter PFO closure therapy has demonstrated benefits in some patients with migraine; however, additional research is required to determine its effectiveness and safety. This article offers a comprehensive review of the current understanding of the link between PFO and migraine and emphasizes the need for further research in this field.
