Modified Technique for Repairing Recurrent Pulmonary Venous Obstruction

Area of Science:

• Cardiovascular Surgery
• Pediatric Cardiology
• Thoracic Surgery

Background:

• Total anomalous pulmonary venous connection (TAPVC) repair can lead to postoperative pulmonary venous obstruction (PVO).
• Upstream PVO, outside the pericardial sac, presents unique surgical challenges.
• Effective management strategies for complex PVO remain critical.

Observation:

• A case of challenging upstream PVO following TAPVC repair is presented.
• The obstruction occurred in the pulmonary vein proximal to the anastomosis, outside the pericardial reflection.
• Standard surgical approaches may be insufficient for such anatomical complexities.

Findings:

• A novel, modified, sutureless technique was successfully employed.
• The technique involved repositioning the pericardial reflection to enlarge the pericardial sac.
• This maneuver effectively relieved the upstream pulmonary venous obstruction.

Implications:

• This sutureless approach offers a promising solution for complex upstream PVO after TAPVC repair.
• The technique may be applicable to other cases requiring pericardial space modification.
• Further research can validate and refine this innovative surgical strategy.
