Summary
This case study details an infant with congenital diaphragmatic hernia and lung sequestration, experiencing severe, intractable persistent pulmonary hypertension of the newborn (PPHN). Novel vasodilator and sildenafil treatment was required when standard therapies failed.
Area of Science:
- Neonatal Medicine
- Pediatric Surgery
- Pulmonology
Background:
- Congenital diaphragmatic hernia (CDH) and extralobar sequestration (ELS) are rare congenital anomalies.
- Combined CDH and ELS present unique diagnostic and management challenges.
Observation:
- A neonate (JG) diagnosed antenatally with left CDH and postnatally with right ELS developed severe persistent pulmonary hypertension of the newborn (PPHN).
- PPHN was refractory to inhaled nitric oxide and extracorporeal life support (ECLS).
Findings:
- Intractable PPHN necessitated a novel therapeutic approach using vasodilators and intravenous sildenafil.
- This combination therapy, previously untried at the institution, proved effective in managing the extreme PPHN.
Implications:
- This case highlights the potential of novel pharmacologic interventions for refractory PPHN in neonates with complex congenital anomalies.
- It underscores the importance of individualized treatment strategies for rare conditions like combined CDH and ELS.
- Further research into advanced PPHN management is warranted.
