Pulmonary infarction following ligation of terminally shunted pulmonary artery
C Marcelletti
The intracardiac repair of tetralogy of Fallot occasionally is complicated
by the presence of a surgically created shunt between a systemic artery and
the distal end of a divided pulmonary artery. Rarely, reconstruction of
this pulmonary artery at the time of corrective operation is not
technically feasible. Usually, this problem has been managed by
obliterating the systemic-to-pulmonary arterial shunt, which has not
previously been reported to result in complications in the involved lung.
Two of our patients underwent intracardiac repair of tetralogy of Fallot,
including ligation of a terminally shunted left pulmonary artery.
Postoperatively they developed infarction of the left lung with resulting
acute respiratory insufficiency. In both instances, conservative management
ultimately achieved resolution of the pathological process and a good
clinical result.
