Transient ischemic attack induced by pulmonary arteriovenous fistula in a child: A case report.

BACKGROUND: Cerebral ischemic stroke is attributed to paradoxical cerebral embolism. Pulmonary arteriovenous fistula (PAVF) is a rare potential cause of cerebral ischemic stroke, and cerebral ischemic stroke induced by PAVF in children is rare. CASE SUMMARY: We report a case of right PAVF that presented as a transient ischemic attack (TIA) in a 13-year-old boy. The patient underwent embolization therapy and remained clinically stable for 2 years after treatment. CONCLUSION: TIA induced by PAVF in children is rare, lacks typical clinical manifestations, and should not be ignored.
