title: [Reconstruction of Unilateral Absent Pulmonary Artery Using Ringed Prosthetic Graft;Report of a Case].
abstract: We have repaired a unilateral absent pulmonary artery(UAPA) using a prosthetic graft with a ring. Case 1 was a 1-month old girl. The right pulmonary artery(RPA) was anti-anatomically reconstructed with a 4 mm ePTFE graft. In postoperative year 1, however, the graft became stenosed due to compression by the ascending aorta. We reversed the stenosis with a 6 mm stent by percutaneous transluminal angioplasty. Case 2 was 6-year old boy. His RPA was anatomically reconstructed with a ringed 5 mm ePTFE graft when he was 5-months old. In postoperative year 6, he needed the graft exchanged because of the relatively decreased pulmonary flow due to body growth. Therefore, we exchanged the graft with an anti-anatomically ringed 12 mm ePTFE graft. No graft stenosis was observed during the perioperative course. Using a prosthetic graft with a ring may be a good solution to avoid compression from the ascending aorta.
