Key result

Dual angiography guides successful lobectomy for neonatal pulmonary sequestration with complex vascular anatomy.

n=1

Key Points

To describe the diagnostic evaluation and surgical management of a neonate with pulmonary sequestration presenting with an atypical dual arterial supply and mixed venous drainage.
Evaluated a term newborn with prenatally suspected left pulmonary sequestration using postnatal thoracic ultrasound, computed tomography, and chest angiotomography.
Performed conventional catheter angiography to map anomalous systemic arterial branches and characterize venous return pathways.
Carried out a left lower lobectomy with surgical dissection and control of all aberrant vessels.
Angiography confirmed two aberrant systemic feeding arteries arising from the descending thoracic aorta to supply the left lower lobe.
Vascular imaging revealed dual mixed venous drainage directed toward both the left atrium via the inferior pulmonary vein and the innominate vein via a left paravertebral collector.
Left lower lobectomy was successfully completed with direct vascular control and a favorable postoperative evolution.

P

Population

1 full-term newborn with prenatal diagnosis of suspected left lower lobe pulmonary sequestration evaluated and surgically treated at a tertiary center.

I

Intervention

Preoperative diagnostic imaging (thoracic ultrasound, chest CT, thoracic CT angiography, and catheter angiography) followed by surgical left lower lobectomy with dissection and control of the aberrant vessels

O

Outcome

Accurate anatomical characterization of the aberrant vascular supply and venous drainage, and postoperative clinical evolution

Limitations

Single case report with no comparative group or long-term follow-up data.

Implication

Comprehensive multimodality vascular imaging, including CT angiography and catheter angiography, is crucial for identifying complex and unexpected arterial and venous variants in congenital pulmonary sequestration to guide safe surgical resection.
