title: Traumatic pulmonary arteriovenous fistula may be misdiagnosed with residual shunt after patent foramen ovale closure.
abstract: We report the case of a 48-year-old woman with a history of transient ischaemic attacks (TIA). The patient was diagnosed with a large patent foramen ovale (PFO), for which she underwent percutaneous PFO closure. Two years postprocedurally, the patient suffered frequent TIA and assessment showed the displacement of the device. The device was surgically removed, and the septum was repaired with a pericardial patch. Afterward, however, the patient experienced repeat TIA. It was discovered that the patient had a pulmonary arteriovenous fistula (PAVF), and a diagnosis of a trauma was made. The PAVF was later coil embolised. This case illustrates the importance of evaluating PFO closure patients for the associated causes of right-to-left shunting.
