Abstract
ABSTRACT For most instances, percutaneous transcatheter intervention has replaced surgical procedure as the preferred treatment for pulmonary arteriovenous fistulas (PAVFs). Despite its efficacy in interventional occlusions of small- to medium-sized PAVFs, “classic” devices such as detachable balloons and intravascular coils are not recommended for bigger fistulas due to the potential risk of embolization to the systemic circulation. This case report is a unique case of a 17-year-old cyanotic girl who had a large symptomatic solitary PAVF that was effectively closed with a 26 mm Amplatzer Septal Occlude (ASO) device. The PAVF was located in the lower right lobe of the lung. The position of the device in situ occluding the feeding channel was verified by computed tomography pulmonary angiography and postprocedure echocardiography, which also revealed the obliteration of the right-to-left shunt.
