Successful occlusion of a large pulmonary arterio-venous fistula with Amplatzer septal occluder in a 16-year-old cyanotic boy.

ABSTRACT: Pulmonary arterio-venous fistula is an uncommon cause of cyanosis and should be suspected when normal cardiac examination is associated without evidence of intra-cardiac shunt. Diagnosis of extra-cardiac shunt can be suspected by contrast echocardiography using agitated saline and confirmation of pulmonary arterio-venous fistula can be made by computed tomography pulmonary angiography with information regarding the size feeding vessels necessary for the planning of intervention. With the advancement of trans-catheter devices, fistula can be occluded successfully by embolotherapy. Coils, duct occluders, and vascular plugs are some of the commonly used trans-catheter devices among the armamentarium. Each device has its own inherent advantages and limitations. However, operators' familiarity
