Critical coarctation in an extremely low birth weight pre-term infant.

Neonatal interventions for critical aortic coarctation may be associated with considerable morbidity and mortality if the patient is extremely premature. We report the successful treatment of critical coarctation in a 25-week, 740-gram infant using initial clipping of the duct until continued prostaglandin E1 infusion delayed end-to-end anastomosis 7 weeks later.
