Ligation of a patent ductus arteriosus can lead to severe cardiorespiratory compromise in preterm infants. This report reviews the postoperative course of a patient with significant cardiorespiratory instability following surgical ligation of the patent ductus arteriosus and presents a framework for enhanced cardiovascular care in this population. A preterm infant, born at 24 wk gestation underwent ligation of a large haemodynamically significant ductus arteriosus after failure of 2 courses of indomethacin. He developed systemic hypotension, which was aggressively treated with high doses of multiple cardiotropic agents. After 10 hr of refractory hypotension, the addition of hydrocortisone normalized blood pressure. This article outlines preprocedural categorization of infants according to ductal illness severity which facilitates the risk assignment for postoperative deterioration, development of clinical guidelines specific to the likely haemodynamic changes, enhanced role of functional echocardiography for guiding therapy, and interprofessional education.
