Thoracotomy-assisted arterial duct stenting in a 1.6-kg infant with Kleefstra syndrome: a case report.

Thoracotomy-assisted arterial duct stenting is a palliative option for patent ductus arteriosus-dependent systemic circulation, typically reserved for infants at high risk for open-heart surgery, such as those with genetic syndromes or very low birth weight. We report the first documented case of thoracotomy-assisted arterial duct stenting in a patient with Kleefstra syndrome, resulting in systemic stabilisation and long-term survival.
