Objective:
To analyze the intraindividual longitudinal development of pulmonary perfusion in children with congenital diaphragmatic hernia (CDH) at ages 2 and 10 years and investigate associations with predictive markers of severe pulmonary hypoplasia, highlighting the clinical significance of these associations.
Key Findings:
- Children with CDH exhibited reduced ipsilateral perfusion with lower PBF and PBV at ages 2 and 10 years, indicating a need for ongoing clinical monitoring.
- Persistent impairment in pulmonary perfusion was observed, suggesting long-term effects of CDH that may impact respiratory function.
- Longitudinal analysis revealed insights into the developmental course of pulmonary perfusion in CDH patients, emphasizing the importance of early intervention.
Interpretation:
The study highlights the importance of longitudinal assessments in understanding the long-term pulmonary perfusion deficits in children with CDH, which may inform future management and follow-up strategies, such as tailored rehabilitation programs.
Limitations:
- Retrospective design may introduce selection bias, potentially affecting the generalizability of the findings.
- Exclusion of patients with bilateral hernia or severe anomalies limits generalizability and may overlook a broader spectrum of CDH cases.
- MRI limitations affected the evaluation of some patients, which could lead to underestimation of perfusion deficits.
Conclusion:
Longitudinal monitoring of pulmonary perfusion in CDH patients is crucial for understanding the progression of pulmonary function and guiding clinical management.
