Bronchial compression as adverse effect of right pulmonary artery stenting in a patient with truncus arteriosus communis and interrupted aortic arch
Aortic arch obstruction and bronchial compression are possible post-operative complications in patients with truncus arteriosus communis (TAC) with interrupted aortic arch (IAA). We present a case of bronchial compression as adverse effect of right pulmonary artery (PA) stenting in an infant with TAC (type 4A)-IAA (type B) repair. Due to growth potential, self-expandable metal stent was applied for postoperative proximal right PA stenosis, which caused bronchial compression. Later, we found patient having bronchomalacia. Surgical removal was needed. Stent insertion might be an option for postoperative PA stenosis, but bronchial compression might be a potential risk particularly in patients with bronchomalacia.
