A Case of Pulmonary Arteriovenous Fistulas Which Showed Enlargement of the Other Fistula and Recanalization of the Treated Fistula after Coil Embolization at Postoperative Remote Term

Abstract

In 1994, a 42-year-old woman was diagnosed with two pulmonary arteriovenous fistulas in right S3 and left S10. 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.
