[A case of the successful treatment of pulmonary artery pseudoaneurysm after PA banding].
Pulmonary artery pseudoaneurysm after PA banding is a rare complication and its mortality is very high. The authors successfully operated on this sort of lesion. To our knowledge, this is the first successful case in Japanese literature. The second of twins was found to be suffering asplenia, dextro cardia, TAPVC, atrioventricular septal defect, corrected TGA and PDA. On the 19th day of life, increasingly pulmonary congestion forced us to operate. We performed PDA ligation, correction of TAPVC, together with extrathoracically adjustable PA banding. 5 months following this operation, spike fever and swelling of anterior thorax were noted. PA angiography was performed, and it showed that the pulmonary artery had been cut through by the band and a pseudoaneurysm had developed. The PA banding was removed and an end-to-end anastomosis of the PA was performed using cardiopulmonary bypass and deep hypothermia with surface cooling. The diameter of the PA anastomosis was designed to be one half that of her aorta. Staphylococcus aureus was cultured from the specimen of the PA band. It was thought to have contributed to the development of this aneurysm. The post operative course was uneventful.
