Síndrome de May Thurner con accidente cerebrovascular isquémico y foramen oval permeable

: The association of cerebral ischemic attack with patent foramen ovale has not been extensively studied, and frequently the site of origin of embolism is not detected despite routine studies. We present the case of a young patient with ischemic stroke and permeable oval foramen in the context of May Thurner syndrome. The May Thurner syndrome is an entity scarcely studied in the medical literature and it has also been infrequently related to ischemic vascular cerebral accident, but in patients with permeable oval foramen without evidence of the emboligen source, it is interesting to rule it out as a cause of paradoxical embolism.
