Summary

Chest radiography in pediatric lung transplant recipients shows nonspecific findings for complications. Early post-transplant complications like acute rejection and infection are common, while chronic rejection appears later.

Area of Science:

  • Pulmonary Medicine
  • Pediatric Surgery
  • Radiology

Background:

  • Lung transplantation is a complex procedure with potential complications.
  • Pediatric lung transplant recipients face unique challenges in managing post-operative complications.

Purpose of the Study:

  • To characterize the spectrum of chest radiographic findings in pediatric lung transplant recipients.
  • To correlate radiographic findings with histopathologic diagnoses of post-transplant complications.
  • To determine the timing of various complications relative to transplantation.

Main Methods:

  • Retrospective review of chest radiographs and histopathologic data from 16 children undergoing 19 lung transplantations.
  • Radiographs assessed for air-space disease, interstitial disease, Kerley B lines, pleural fluid, and cardiac size.

  • Histopathologic diagnoses from 51 biopsy specimens analyzed.

    • Main Results:

    • Nonspecific radiographic patterns were observed across different complications.
    • Acute rejection (79%) and infection (64%) predominantly occurred within 5 weeks post-transplant.
    • Chronic rejection (63%) was more common after 5 weeks post-transplant.

    Conclusions:

    • Chest radiography alone is insufficient for diagnosing complications in pediatric lung transplant recipients.
    • Clinical and histopathologic findings are crucial for accurate diagnosis and management.
    • Timing of complications can suggest potential diagnoses, aiding clinical decision-making.
