[Surgically treated cases of pulmonary arteriovenous fistula]

We report three cases of pulmonary arteriovenous fistula (PAVF) in which we performed limited resection. Case 1: female, 75 of age. CT and pulmonary angiography revealed PAVF of 2 cm in diameter in the right S8, and partial resection was performed. Case 2: female, 45 of age. CT and pulmonary angiography revealed PAVF of 7 cm in diameter in the right S10, and occlusion of fistula was performed. Case 3: male, 43 of age. CT pulmonary angiography and 3 D-CT revealed PAVF of 3 cm in diameter in the right S6, and occlusion of fistula was performed. The last case was accompanied by Rendu-Osler-Weber disease. Three patients showed a good postoperative course, without developing new fistula. Occlusion of fistula allows to close feeding artery and draining vein safely and securely. Considering invasion and preservation of pulmonary function after surgery, occlusion of fistula may be a primary option for treating PAVF.
