Patent ductus arteriosus stent and modified Blalock-Taussig shunt as palliation for infants with ductal-dependent pulmonary blood flow


eMediNexus    24 February 2018

Infants with ductal-dependent pulmonary blood flow may require palliation with either a patent ductus arteriosus (PDA) stent or a modified Blalock-Taussig (BT) shunt. However, there is a scarcity of data on the balanced multicenter comparison between these two approaches. The study published in the Circulation journal showed that there was no difference in the primary end point, death or unplanned re-intervention to treat cyanosis. Other markers of morbidity and pulmonary artery size favored the PDA stent group. This group had a lower adjusted intensive care unit length of stay, a lower risk of diuretic use at discharge and procedural complications. These findings suggest PDA stent as a suitable alternative option to BT shunt in selected patients.
