摘要：

Patent foramen ovale (PFO) has been linked to ischemic strokes of undetermined cause (cryptogenic strokes). PFO-a remnant of fetal circulation when the foramen ovale does not seal after birth-can permit microemboli to escape the pulmonary filter into the intracranial circulation, causing stroke. Coexistent atrial septal aneurysm, pelvic deep vein thrombosis and inherited clotting factor deficiencies could potentiate stroke risk in patients with PFO. Transcatheter PFO closure, a minimally invasive procedure, is one technique used to prevent recurrent cerebrovascular events. A connection between PFO and migraine headache has been conceptualized from retrospective evidence of reduced migraine frequency and severity after PFO closure; however, prospective randomized trials are needed to verify the efficacy of PFO closure on migraine prevention. In this review we discuss embryologic origins, diagnostic techniques and treatment options for prevention of paradoxical embolism thought to be related to PFO, and the relation of PTO to cryptogenic stroke and migraine.
