Background : Patients with non-confluent central pulmonary artery (CPA) and ductus-dependent pulmonary circulation may undergo multiple surgical and catheter interventions for the pulmonary arteries after confluent central pulmonary artery is reconstructed

Methods : Between 2005 and 2016, 16 patients (10 males, 6 with functionally single ventricle) with non-confluent CPA underwent surgical interventions for the reconstruction of CPA. Median age at operation was 26 days (range, 6 to 345). Pulmonary blood flow to the disconnected pulmonary artery was supplied by the left ductus in 8 and by the bilateral ductus in 8. Surgical techniques for the reconstruction of the CPA were pericardial roll interposition in 5 and direct anastomosis of the peripheral PAs with or without anterior wall patch augmentation in 11.

Results : There were no early mortality and 4 late mortality (4/16, 25%). Median reoperations or interventions for peripheral pulmonary arteries were 2 (range 0 to 7). Overall survival and Freedom from surgical or catheter intervention for PA stenosis at 1 year were 87.5±8.3% and 25±10.8%, respectively. On Cox proportional hazards modeling, bilateral ductus at initial diagnosis was identified as a risk factors for early reoperation or intervention (HR: 4.93, 95% CI: 1.29-18.85, P=0.02)

Conclusion : In patients with non-confluent CPA with ductus-dependent pulmonary circulation were almost required additional procedure after initial surgical intervention
