This case report
describes a 7 kg male with double inlet right ventricle, transposition of the
great arteries and pulmonary atresia admitted to Stollery Children’s Hospital,
Edmonton, Alberta for bidirectional Glenn (BDG) and patch augmentation of the
left pulmonary artery (LPA).
The patient had
undergone three previous operations, initially a
right modified Blalock-Taussig shunt (3.5mm), followed by several attempts to
recruit the LPA by bovine pericardial patch. He was palliated with a BDG and
LPA autologous pericardial patch.
The LPA
thrombosed accepts for its intraparenchymal portion. Given the presence of
ongoing hypoplasia and acute thrombosis of the LPA, the decision was made to
place a central shunt with the aim of securing pulmonary blood flow to the left
lung and augmenting growth of peripheral vasculature.
