Bronchial compression as adverse effect of left pulmonary artery stenting in a patient with hypoplastic left heart syndrome.
A 5-year-old child with hypoplastic left heart syndrome (HLHS) was noted to have left pulmonary artery stenosis after Glenn shunt placement. Therefore, a stent was implanted into the left pulmonary artery to relieve stenosis. After redilatation of the pulmonary artery stent, wheezing, fatigue, asymmetric bronchial sound, and desaturation was noted. Computed tomography, bronchoscopy, and bronchography confirmed critical left main bronchus compression as a consequence of the mass effect of the dilated stent. Balloon plasty of the left bronchus successfully relieved bronchial stenosis. Tracheobronchial obstruction is a possible adverse effect of vascular stenting in children with congenital heart defects. Balloon plasty seems to be a safe and efficient therapeutic option in those cases.
