Dois pacientes portadores de Transposiçäo de grande artérias submetidos a cirurgia de Jatene aos seis dias e aos seis meses de idade apresentaram no período pós-operatório estenose na anastomose aorto-pulmonar, diagnosticada aos 3§ e 6§ anos de evoluçäo. Procedeu-se a angioplastia transluminal percultânea da referida obstruçäo, com sucesso, seis meses e imediatamente após o diagnóstico, respectivamente. Houve reduçäo dos gradientes de pressäo, respectivamente de 83 mmHg para 24 mmHg, e de 76 mmHg para 13 mmHg, com nítda melhora do aspecto angiográfico. Nenhum dos pacientes apresentou complicaçöes durante ou após o procedimento. Esta aplicaçäo da angioplastia trasluminal percutânea, inédita na literatura, deve ser cogitada como alternativa a correçäo cirúrgica da estenose do "novo" tronco pulmonar da cirurgia de Jatene
Two patients with transposition of the great arteries submitted to Jatene surgery at ages of 6 days and 6 months respectively, presented in the postoperative period stenosis of the aorto-pulmonary anastomosis. The diagnosis was made three and six years after the surgery. In both patients successful percutaneous transluminal angioplasty (PTA) was performed, respectively six months and immediately after the diagnosis. Pressure gradients decreased from 83 mmHg to 24 mmHg in the first case, and from 76 mmHg to 13 mmHg in the other case, with clear improvement of the angiographic image. Complications of the procedure did not occur in any case. This application for PTA was not previously reported and should be considered as an altennative to the surgical correction of the new pulmonary trunk stenosis in the Jatene surgery
