[Three cases of chronic respiratory failure]

Area of Science:

• Pulmonology
• Critical Care Medicine
• Transplantation Surgery

Background:

• Presents three long-term hospitalized patients with severe chronic respiratory failure.
• Details diverse etiologies including emphysema, cystic bronchiectasis, and familial pulmonary fibrosis.

Observation:

• Case 1: 57-year-old male with emphysema, Pseudomonas aeruginosa infection, bronchial fistula, and aortic insufficiency.
• Case 2: 41-year-old male with cystic bronchiectasis, chronic Pseudomonas infection, and respiratory support dependency.
• Case 3: 27-year-old male with familial pulmonary fibrosis, refractory to corticosteroids, who died from respiratory failure.

Findings:

• All patients exhibited severe pulmonary dysfunction and significant comorbidities.
• Chronic Pseudomonas aeruginosa infection was a common factor in two cases.
• Lung and heart-lung transplantation are explored as potential, yet complex, options.

Implications:

• Highlights the critical need for advanced treatment strategies for end-stage respiratory failure.
• Underscores the medical and social barriers to implementing lung transplantation in Japan.
• Suggests careful consideration of transplant indications for patients with severe, chronic respiratory conditions.
