Congenital diaphragmatic hernia-associated pulmonary hypertension
Topic overview
This article addresses pulmonary hypertension in neonates with congenital diaphragmatic hernia, a major determinant of morbidity and mortality. It reviews pathophysiology, diagnostic approaches, and management strategies for CDH-associated pulmonary hypertension in the perioperative period.
Key takeaways
- CDH-associated pulmonary hypertension results from pulmonary hypoplasia and abnormal vascular remodeling in utero.
- Echocardiography is the primary tool for diagnosing and monitoring pulmonary hypertension severity in CDH patients.
- Management includes optimizing ventilation, oxygenation, and targeted pulmonary vasodilator therapy (inhaled NO, sildenafil).
- ECMO may be required for refractory pulmonary hypertension with severe right ventricular failure despite medical therapy.
- Long-term follow-up is essential as pulmonary hypertension can persist or develop after initial CDH repair.
