Abstract:To systematically analyze whether there is benefits of patent foramen ovale(PFO) closure in patients with migraine with aura(MA+). Methods Papers on the effect of PFO closure of migraine and/or MA+ in randomized controlled trials and cohort studies were retrieved from a number of foreign and domestic database.The data was analyzed by Review Manager 5.3. Results Three randomized controlled trials and two cohort studies were included in this analysis, including 362 patients. Meta-analysis showed, reduction in monthly migraine attacks/days ≥50% was higher in PFO closure compared with the control group[OR = 4.29,95% CI( 2.67,6.97),P <0. 00001].There was higher reduction of monthly migraine days in PFO closure group compared with control group[MD = -1.62,95% CI( -3.01,-0.24),P =0. 02].Conclusion PFO closure might be beneficial in migraine with aura patients by reducing migraine attacks and migraine days.
