Abstract

While there is a high prevalence of patent foramen ovale in adults, paradoxical embolism via a patent foramen ovale is rare. Previous echocardiographic studies indicated that paradoxical embolism might only occur in patients with high-risk features of patent foramen ovale (i.e., large defect size, presence of a Eustachian valve, and high right atrial pressure). Here, we present a case of patent foramen ovale with high-risk CT features for paradoxical embolism.

난원공개존증은 정상 성인에서 흔히 발견된다. 그러나, 임상에서 난원공개존증에 의한 기이색전증은 드물다. 심장 초음파를 이용한 이전 연구에 따르면, 기이색전증은 큰 직경이며, 유스타키오관이 동반되고, 좌우 심방의 압력차가 큰 난원공개존증에서 주로 발생하였다. 저자들은 기이색전증이 발생한 난원공개존증 환자 1예의 특징적인 CT 소견을 제시한다.
