Coil embolization was performed for the left S10 fistula. In September 2010, chest enhanced computed tomography (CT) showed enlargement of the other fistula and recanalization of the treated fistula. Coil embolization was performed in the right S3 fistula the following year. Angiogram of left pulmonary artery displayed recanalization of the fistula in left S10. Pulmonary arteriovenous fistula may grow in natural course. In addition, recanalization after coil embolization should be noted. Therefore, regular follow-up using enhanced computed tomography is necessary. (J Jpn Coll Angiol 2013; 53: 121 125) Online publication August 10, 2013
