Summary
Pulmonary lobar transplantation shows potential for addressing donor shortages. Early chest roentgenograms indicate that lobar lung allografts can achieve good expansion with minimal infiltrates, suggesting clinical applicability.
Area of Science:
- Thoracic surgery
- Transplantation immunology
- Radiology
Background:
- Acute donor shortage is a significant challenge in lung transplantation.
- Pulmonary lobar transplantation is being explored as a potential solution.
Purpose of the Study:
- To evaluate the experimental and clinical feasibility of pulmonary lobar transplantation.
- To assess lung expansion and infiltrates in lobar lung allografts using sequential chest roentgenograms.
Main Methods:
- Twenty-two mongrel dogs underwent left lower lobar transplantation after pneumonectomy.
- Anastomoses were performed for the pulmonary vein, artery, and bronchus.
- A grading system evaluated lung expansion and infiltrate extent on early postoperative radiographs.
Main Results:
- Good to excellent lung expansion was observed in a significant proportion of dogs in the early postoperative period (e.g., 6/10 on day 0).
- Clear to minimal infiltrates were prevalent in the early postoperative period (e.g., 8/10 on day 0).
- A correlation between good expansion and minimal infiltrates was noted in some cases.
Conclusions:
- Pulmonary lobar transplantation demonstrates potential for addressing lung allograft shortage.
- Early radiological assessment suggests acceptable graft expansion and infiltrates in this experimental model.
- Further research is warranted to confirm the clinical applicability of lobar lung transplantation.
