摘要
卵圆孔未闭(patent foramen ovale,PFO)是指婴儿出生后,卵圆孔未能自然闭合,使左右心房间的仍存在异常通道。PFO是一种常见于儿童的疾病,大部分病例并无明显症状,但部分病例会出现不明原因的晕厥等症状。晕厥是小儿常见的一种症状,其发病机制复杂,涉及多种因素,如心血管系统和神经系统。本文对儿童卵圆孔未闭合导致不明原因晕厥的临床特征及研究进展进行了探讨。
Patent Foramen Ovale(PFO)refers to the failure of the foramen ovale to close naturally after birth,resulting in an abnormal passage between the right and left atria.PFO is a common condition in children.Most cases present without noticeable symptoms,but some may experience unexplained syncope.Syncope is a frequent symptom in pediatrics with complex pathogenesis involving multiple factors,such as cardiovascular and neurological systems.This article explores the clinical features and research advances regarding unexplained syncope caused by PFO in children.
