[Three cases of transcatheter embolization for pulmonary arteriovenous fistula using detachable coils].
We report three cases of transcatheter embolization for pulmonary arteriovenous fistula (PAVF) using Interlocking detachable coils (IDC) and detachable fibered coils (DFC), and evaluate the outcome of transcatheter embolization with reference to previous reports. The three patients were women aged 56, 70 and 71 years. They had no symptoms, but chest radiographs were abnormal. None of them had Rendu-Osler-Weber disease. The three PAVFs were of the simple type, with a single feeding vessel and a single draining vein. In case 1, the feeding vessel arose from the left A4, while the feeding vessels in case 2 and 3 arose from the left A5. In case 1, we embolized the venous sac with detachable coils because the feeding vessel was short and kinked. In case 2 and 3, we embolized the feeding vessels closer as to the neck of the venous sac using detachable coils. The three PAVFs were all successfully embolized without severe complications, and transcatheter embolization seems to be an effective therapy.
