Background. This study examined the results of a Fontan operation for patients with acquired atresia of one main branch pulmonary artery. Methods. The data for 7 patients identified as having a hypoplastic left pulmonary artery discontinuous from the right pulmonary artery were compared with those for 65 patients with continuous pulmonary arteries who consecutively underwent a completion Fontan procedure. Results. No significant differences were found preoperatively with respect to right atrial pressure, aortic saturation, ventricular end-diastolic pressure, pulmonary artery pressure, pulmonary blood flow, or pulmonary vascular resistance. In the first 24 postoperative hours, there were no significant differences in heart rate, urine output, systemic venous pressure, or pulmonary venous pressure. Also, data regarding hospitalization length, effusions, and mortality were similar between the two groups. Postoperative systemic arterial saturation was lower in the one-lung group. There were no early postoperative deaths in the one- lung group, and 5 of the 7 patients are long-term survivors. Conclusions. A completion Fontan procedure can be successfully performed in patients with a hypoplastic and discontinuous left pulmonary artery, although postoperative systemic arterial saturation is not as high as in patients with continuous pulmonary arteries.
