Pulmonary Vein in a Pinch

Area of Science:

• Cardiology
• Thoracic Surgery
• Radiology

Background:

• Pulmonary veins typically drain into the left atrium, located anterior to the right pulmonary arteries.
• Anatomical variations in pulmonary venous return can occur, though rare.

Observation:

• A patient presented with atypical chest pain, prompting further investigation.
• Coronary computed tomography angiography was utilized for diagnostic imaging.

Findings:

• An extremely rare pulmonary vascular anomaly was identified.
• The right superior pulmonary vein coursed posterior to the right pulmonary artery (RPA).
• The aberrant vein was compressed between the RPA and the right main bronchus.

Implications:

• This anomaly may be a cause of atypical chest pain.
• Accurate diagnosis through advanced imaging is crucial for understanding such rare conditions.
• Knowledge of these variations is important for thoracic surgeons and interventional cardiologists.
