Management of Bilateral Partial Anomalous Pulmonary Venous Connection

Area of Science:

• Cardiovascular Surgery
• Congenital Heart Disease
• Thoracic Surgery

Background:

• Partial anomalous venous connections (PAVC) are rare congenital abnormalities where pulmonary veins connect to the systemic venous circulation instead of the left atrium.
• Bilateral PAVC presents unique surgical challenges, often requiring complex reconstructions to ensure proper blood flow and prevent complications.

Observation:

• A case of bilateral partial anomalous venous connections is presented, highlighting the rarity and complexity of this condition.
• The patient underwent a modified Warden procedure, a surgical approach designed to correct anomalous venous connections.

Findings:

• The modified Warden procedure successfully rerouted the superior vena cava and associated anomalous veins to the left atrium.
• Reconstruction of the innominate vein and superior vena cava was achieved using a polytetrafluoroethylene conduit to the right atrial appendage.
• Crucially, the procedure avoided the use of foreign materials within the pulmonary venous pathway, mitigating risks of obstruction.

Implications:

• This surgical approach offers a viable solution for complex bilateral partial anomalous venous connections.
• The successful outcome demonstrates the efficacy of the modified Warden procedure in preventing pulmonary venous obstruction.
• This case contributes to the understanding and management of rare congenital heart anomalies.
