This option might be even more advisable in low\u2010weight neonates (&lt;2.5 kg), who are at higher surgical risk and in whom stent redilation might adapt shunt magnitude to patient's growth. <jats:styled-content>Methods:<\/jats:styled-content> Between April 2003 and September 2010, 76 neonates with CHD\u2010DPC underwent AD stenting at our institution, as lower\u2010risk palliation with respect to surgical shunt. Procedural and follow\u2010up data of the 15 low\u2010weight newborns (2.0 \u00b1 0.3 kg, median 2.2) (group I) were compared with the remaining normal\u2010weight newborns (3.5 \u00b1 0.7 kg, median 3.2) (group II). <jats:styled-content>Results:<\/jats:styled-content> Feasibility, complication rate, and need for surgical shunt did not significantly differ between groups. Global X\u2010ray exposure was significantly higher in the low\u2010weight group (82 \u00b1 108 vs. 30 \u00b1 33 Gray\/cm<jats:sup>2<\/jats:sup>, <jats:italic>P<\/jats:italic> &lt; 0.002), which maybe due to a longer angiographic presenting work\u2010up. In\u2010hospital mortality rate was 14.3% (vs. 1.9% in the group II, <jats:italic>P<\/jats:italic> = NS), although none of the fatalities was procedure\u2010related. During follow\u2010up, five patients (35.7% vs. 15.7% in the group II, <jats:italic>P<\/jats:italic> = NS) underwent stent redilation before surgical repair. At control angiography, the Nakata and McGoon indexes had significantly increased (<jats:italic>P<\/jats:italic> &lt; 0.05 for both comparisons), without any significant difference with the group II (162 \u00b1 52% vs. 144 \u00b1 158% and 40 \u00b1 17% vs. 42 \u00b1 38%, <jats:italic>P<\/jats:italic> = NS). <jats:styled-content>Conclusions:<\/jats:styled-content> AD stenting is also feasible and effective in low\u2010weight newborns with CHD\u2010DPC, supporting the spontaneous improvement process or promoting a significant pulmonary artery growth. \u00a9 2011 Wiley\u2010Liss,
