Description
Akinobu Ito and colleagues report a 2026 stroke case with an unusual chain of causes. Their patient was a 54-year-old woman found collapsed at home, with weakness and speech problems from a blocked middle cerebral artery. Doctors removed the clot by thrombectomy, and her symptoms improved.
Proving a paradoxical embolism, where a vein clot crosses into the arteries, usually requires finding the vein clot first. Repeated leg ultrasounds showed none. Heart imaging instead revealed a patent foramen ovale, a small opening between the heart chambers, while a chest scan found a clot in a lung artery. Blood thinners cleared that clot with no recurrence. The authors argue the lung artery clot can stand as the venous evidence when leg scans stay negative.
