Pulmonary Sequestration Supplied By The Circumflex Artery - A Rare Case Report

Area of Science:

• Cardiology
• Thoracic Surgery
• Medical Imaging

Background:

• Pulmonary sequestration (PS) is a rare congenital lung malformation.
• Coronary artery supply to PS is exceptionally uncommon.
• This case highlights a unique presentation of PS.

Observation:

• A 68-year-old man presented with acute coronary syndrome.
• Coronary angiography revealed an anomalous artery from the circumflex artery supplying a left lower lobe mass.
• No significant coronary artery disease was found.

Findings:

• The anomalous artery was identified as the vascular supply for the pulmonary sequestration.
• A coronary steal phenomenon was the proposed mechanism for the patient's cardiac symptoms.
• Surgical ligation of the aberrant vessel and resection of the sequestered lung segment were performed.

Implications:

• This case expands the spectrum of PS vascular supply and presentation.
• It underscores the importance of considering non-coronary causes in acute coronary syndromes.
• Successful surgical management offers a potential treatment for this rare condition.
