Novel arterioplasty using native main pulmonary artery to repair
nonconfluent left pulmonary artery
Abstract
There are multiple surgical approaches described to repair the left
pulmonary artery (LPA). Regardless of the technique used, rate of
restenosis is very high. We describe a case of discontinuous LPA which
was treated by turning down the entire autologous main pulmonary artery
(MPA) and creating a direct anastomosis between the MPA and LPA. This
was in background of tricuspid and pulmonary atresia, hypoplastic right
ventricle with atrial and ventricular septal defects and ductus
arteriosus feeding the left pulmonary artery. This new technique
resulted in a tension free tissue-tissue anastomosis with potential for
growth and produced hemodynamically gratifying short-term results.
