Delayed surgery in pericardial teratoma with neonatal hydrops.

Timing of neonatal surgery in cases of pericardial teratoma with hydrops is not standardised. We report two cases of hydropic premature newborns with pericardial teratoma in which surgery was delayed until respiratory and haemodynamic stabilisation. Mature teratoma was removed on day 3. The newborns were weaned from the ventilator on postoperative day 5 and 10, respectively. Both infants were doing well at 18 months, suggesting delayed surgery may be feasible and effective.
