[Clinical experience using percutaneous cardiopulmonary support system for stent replacement]

Area of Science:

• Cardiothoracic Surgery
• Pulmonology
• Interventional Bronchoscopy

Background:

• Tracheal and main bronchus stenoses can cause severe dyspnea, often necessitating complex interventions.
• Management of airway stenosis is challenging, particularly when lung ventilation is compromised.
• Percutaneous cardiopulmonary support (PCPS) offers a potential solution for maintaining systemic oxygenation during airway procedures.

Observation:

• Three patients with severe tracheal or main bronchus stenosis underwent stent placement procedures.
• Case 1: 63-year-old male with lung cancer invading the trachea; treated with YAG-laser and Dynamic stent under PCPS.
• Case 2: 74-year-old male with lung cancer invading the right main bronchus; treated with Dumon Y stent under PCPS.
• Case 3: 57-year-old male with ischemic tracheal and left main bronchus stenosis post-esophageal cancer surgery; treated with Dynamic stent under PCPS.

Findings:

• Successful dilation of stenotic segments and stent placement in all three cases.
• All patients tolerated the procedures well, with no intra-procedural or post-procedural complications.
• PCPS provided essential hemodynamic and respiratory support, enabling successful airway interventions.

Implications:

• PCPS is a valuable and effective tool for managing complex tracheal and main bronchus stenoses.
• This approach facilitates interventions in patients with compromised lung function or ventilation.
• The findings support the use of PCPS as a safe and satisfactory method for airway stenting in critical cases.
