Abstract:
A 6-month-old baby boy had undergone the Jatene procedure at 4 days. Four months later, catheter intervention (balloon angioplasty) was performed because of severe stenosis at the bifurcation of the pulmonary arteries. Twenty days later, several episodes of cyanosis occurred and he was readmitted. The existence of shunt flow between the sinus of valsalva and the pulmonary bifurcation was detected by echocardiography and examination by 16-row MDCT revealed 2 holes at this site. Under a diagnosis of aortopulmonary (AP) window, the patient was placed on cardiopulmonary bypass and the pulmonary artery was opened after aortic clamping. There was a ridge between the bifurcation of the pulmonary arteries. After removing it, 2 holes were visualized that resembled the findings on 16-row MDCT. These holes were closed with Xenomedica patches and the main pulmonary artery was also extended with a Xenomedica patch. AP window is a rare complication after balloon angioplasty for pulmonary stenosis, but we must take great care to prevent this complication.
