Plastic bronchitis: symptomatic improvement after pulmonary arterial stenting in four patients with Fontan circulation

Plastic bronchitis is a severe complication after a Fontan procedure, with an estimated incidence around 1-2% and poor prognosis. We present the cases of four patients with plastic bronchitis after a total cavopulmonary connection with a stenosis of the left pulmonary artery that was stented successfully. In three of the four patients, symptoms improved after catheter intervention in combination with pulmonary vasodilator and inhalative treatment.
