Objective To summarize the procedures and outcomes of interventional therapy for huge pulmonary arteriovenous fistula. Methods The treatment procedures of 9 patients with huge pulmonary arteriovenous fistula whose inlet blood vessels were larger than 5 mm in diameter were retrospectively analysed. The appearance, size and route of the fistula were learned by right heart catheterization and pulmonary arteriography before interventional therapy, the inlet vessels to be occluded were determined, and the diameters were accurately measured. The occlusion was performed with Amplatzer Plug or domestic PDA occluders. Results The number of inlet blood vessels was 11 in 9 patients, and all the occlusion was successfully performed. Six Amplatzer Plug and 4 domestic PDA occluders were placed. Femoral arterial oxygen saturation significantly increased to the normal level. Conclusion Transcatheter occlusion of huge pulmonary arteriovenous fistula with inlet blood vessel larger than 5 mm in diameter by Amplatzer Plug or domestic PDA occlude is an effective and safe interventional therapy.
