[Dextrocardia of post right pneumonectomy]

Area of Science:

• Thoracic Surgery
• Cardiovascular Physiology
• Diagnostic Imaging

Background:

• Lung pneumonectomy, the surgical removal of an entire lung, can lead to mediastinal shifts due to negative intrathoracic pressure and contralateral lung expansion.
• While mediastinal changes are known, significant displacement after adult pneumonectomy is uncommon.
• Right lung pneumonectomy poses a higher risk for mediastinal complications affecting great vessels and atria compared to left-sided procedures.

Observation:

• A case study of a young woman who underwent right lung pneumonectomy at age ten.
• Sixteen years post-surgery, a severe mediastinal re-shuffle was identified.
• The heart was significantly displaced into the right hemithorax, presenting as dextrocardia.

Findings:

• The long-term consequence of right lung pneumonectomy in this patient was a substantial mediastinal shift.
• The observed dextrocardia-like presentation resulted from the heart's displacement.
• This case illustrates the potential for delayed and severe complications following pediatric pneumonectomy.

Implications:

• This case highlights the importance of long-term monitoring for patients who have undergone pneumonectomy, particularly in childhood.
• It presents diagnostic challenges, requiring differentiation from primary dextrocardia and other cardiac or thoracic anomalies.
• Understanding these rare but serious sequelae is crucial for surgical planning and patient management in thoracic surgery.
