The efficacy of post-intervention pain relief was evaluated using an 11-point numerical rating scale (NRS-11), headache impact test-6 (HIT-6), and Paediatric Migraine Disability Assessment Score (PedMIDAS), migraine frequency, and duration of each migraine attack.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>At the 1-month follow-up after PFO closure, 20 patients (57.1%) achieved complete relief, and 29 (82.9%) had a reduction in migraine attack frequency by &amp;gt;50%. At the 12-month follow-up, 28 patients (80%) achieved complete relief, and 32 (91.4%) had a reduction in migraine attack frequency by &amp;gt;50%. There were no statistically significant differences between the aura and the non-aura groups.
