Corrected partial anomalous pulmonary vein connection associated with lung resection: a case report

Area of Science:

• Cardiovascular Surgery
• Thoracic Oncology
• Medical Case Reports

Background:

• Partial anomalous pulmonary venous connection (PAPVC) can lead to right-sided heart failure and poses risks during lung surgery.
• Co-occurrence of PAPVC and lung cancer requiring lobectomy is rare.
• This report addresses a specific case of PAPVC complicating lung cancer surgery.

Purpose of the Study:

• To describe a rare case of left lower lung lobectomy for lung cancer in a patient with PAPVC.
• To illustrate the surgical technique for correcting PAPVC during lung cancer resection.
• To highlight the successful management of a complex cardiovascular anomaly during thoracic surgery.

Main Methods:

• A 66-year-old male patient with lung adenocarcinoma underwent left lower lobectomy.
• Preoperative imaging identified PAPVC involving the left upper pulmonary vein connected to the left brachiocephalic vein.
• Surgical correction involved ligating the PAPVC and anastomosing the left upper pulmonary vein stump to the left atrial appendage without cardiopulmonary bypass.

Main Results:

• The surgical procedure was completed successfully without cardiopulmonary bypass.
• Postoperative imaging confirmed the patency of the reconstructed vessels and absence of right ventricular overload.
• The patient experienced an uneventful postoperative recovery and follow-up.

Conclusions:

• This case demonstrates the feasibility and success of surgical correction of PAPVC during lung cancer lobectomy.
• The described technique provides valuable insights for managing similar complex cases in clinical practice.
• Successful management can improve outcomes for patients with combined thoracic and cardiovascular conditions.
