Background Whether closure of a patent foramen ovale is effective in the prevention of recurrent ischemic stroke in patients who have had a cryptogenic stroke is unknown. Patent foramen ovale (PFO) is the persistent patency of a congenital opening or foramen ovale in the interatrial septum, which normally closes after birth. In this situation, right-to-left shunting will occur if the foramen ovale is patent. The patent foramen ovale (PFO) is a remnant of the fetal circulation. 1.

Percutaneous closure of patent foramen ovale (PFO) is widely performed to prevent recurrent stroke or transient ischemic attack in patients with cryptogenic stroke. •The estimated strength of association between PFO and migraine was 5.13, and between PFO and migraine with aura the OR was 3.21. When a PFO is felt to be very likely responsible for a patient’s stroke, PFO closure provides a moderate benefit for patients under the age of 60 years. In a significant proportion of individuals, the primum and secundum atrial N Engl J Med. In the fetus, the foramen ovale is an opening which allows blood from the right atrium to enter the left one to bypass the circulation coming from the lungs. PFO is the consequence of failed closure of the foramen ovale, a normal structure that exists in the fetus to direct blood flow directly from the right to the left atrium, bypassing the pulmonary circulation.

When compared with a control general population of 200 people where the prevalence of PFO was 18% as determined by a TCD grade ≥3, patients with cryptogenic stroke with or without migraine had significantly greater prevalence of PFO (χ 2 , P <0.00001 and χ 2 , P <0.00001, respectively).
