Abstract:
Pulmonary arteriovenous fistula(PAVF)and patent foramen ovale(PFO)are significant contributors to ischemic stroke,as intracardiac or pulmonary shunts facilitate right-to-left shunting,leading to hypoxemia symptoms.While pulmonary angiography is considered the"gold standard"for PAVF diagnosis,its invasive nature often limits its ability to detect small,diffuse PAVFs;thus,it is not routinely employed prior to surgical intervention.In contrast,multi-slice spiral CT provides a clear visualization of the pulmonary vascular anatomy and pathological characteristics,achieving diagnostic accuracy comparable to that of DSA.This article presents a case in which a radiologist overlooked the diagnosis during pulmonary artery CTA but successfully identified and performed interventional embolization of a pulmonary arteriovenous fistula intraoperatively;following this intervention and appropriate supportive care,the patient made a full recovery.
