Effects of PFO Closure on Glymphatic Function and Clinical Symptoms in Patients With Migraine

Patent Foramen Ovale (PFO) is a common congenital heart defect. Recent studies have suggested a potential association between PFO and migraines, particularly migraine with aura. It is hypothesized that PFO may allow microemboli or vasoactive substances from venous blood to bypass pulmonary metabolism and enter the arterial system directly, potentially triggering migraines. Although PFO closure has been shown to reduce the frequency and severity of migraine attacks, its long-term efficacy and underlying mechanisms require further investigation. This study aims to explore the characteristics of glymphatic system function in PFO patients and its relationship with migraine symptoms, as well as the impact of PFO closure on glymphatic function and its role in alleviating migraine symptoms. A case-control and self-controlled before-after study design is adopted. Two groups of participants are enrolled: a case group consisting of PFO patients with significant right-to-left shunt and migraine, and a control group comprising PFO patients with significant shunt but without migraine. According to clinical guidelines and after obtaining informed consent, eligible patients in the case group undergo percutaneous PFO closure. By comparing migraine symptoms and glymphatic function indicators both before and after the procedure between the two groups, the interventional effect of PFO closure and its potential mechanism will be investigated. The primary endpoint is the improvement in migraine…
