摘要

BACKGROUND:Infants with ductal-dependent pulmonary blood flow may undergo palliation with either a patent ductus arteriosus (PDA) stent or a modified Blalock-Taussig (BT) shunt. A balanced multicenter comparison of these 2 approaches is lacking.
METHODS:Infants with ductal-dependent pulmonary blood flow palliated with either a PDA stent or a BT shunt from January 2008 to November 2015 were reviewed from the 4 member centers of the Congenital Catheterization Research Collaborative. Outcomes were compared by use of propensity score adjustment to account for baseline differences between groups.
RESULTS:One hundred six patients with a PDA stent and 251 patients with a BT shunt were included. The groups differed in underlying anatomy (expected 2-ventricle circulation in 60% of PDA stents versus 45% of BT shunts; P=0.001) and presence of antegrade pulmonary blood flow (61% of PDA stents versus 38% of BT shunts; P

背景: 患有导管依赖性肺血流的婴儿可能会接受动脉导管未闭 (PDA) 支架或改良 Blalock-Taussig (BT) 分流术的缓解。缺乏这两种方法的平衡多中心比较。
方法: 从先天性导管插入研究合作的 4 个成员中心回顾了 2008年1月至 2015年11月期间，导管依赖性肺血流通过 PDA 支架或 BT 分流减轻的婴儿。通过使用倾向评分调整来比较结果，以解释组间的基线差异。
结果: 包括 100 名 PDA 支架患者和 251 名 BT 分流患者。两组在基础解剖结构上有所不同 (60% 的 PDA 支架预期的 2 心室循环与 45% 的 BT 分流; P = 0.001) 以及顺行性肺血流的存在 (61% 的 PDA 支架与 38% 的 BT 分流; P
