A patch technique for reconstruction of stenotic pulmonary bifurcation in a Rastelli-type operation after palliations for cyanotic congenital heart disease. A report of two cases.
A Rastelli-type operation was successfully performed on two patients with cyanotic congenital heart disease with pulmonary artesia (PA) and severe stenosis or obstruction of the pulmonary bifurcation, following the improvement of a pulmonary artery index (PA index) after palliative systemic pulmonary shunts. It is a point that stenotic or obstructive pulmonary bifurcation was reconstructed by a patch technique. An extracardiac conduit was used a combination of a bicuspid valved pericardial roll and a prosthetic vessel graft. In a 5-year-old male with an extreme type of tetralogy of Fallot associated with PA and patent ductus arteriosus (PDA), the enlargement of stenotic pulmonary bifurcation was attempted using a brimshaped equine pericardial patch in order to get sufficient suture margin and be safely anastomosed with a conduit. In a 6-year-old female with complete transposition of the great arteries, PA, PDA and right aortic arch (RAA), an obstructive pulmonary bifurcation behind the RAA was enlarged using a brimshaped equine pericardial patch. The attachment of the conduit was shifted to the left pulmonary artery to avoid compression of an extracardiac conduit and pulmonary artery behind RAA. Reconstruction of the pulmonary bifurcation using an equine pericardial patch is useful to anastomose an extracardiac conduit and the stenotic or obstructive pulmonary bifurcation.
