Anomalous systemic arteries supplying normal lung segments can mimic intralobar pulmonary sequestration. Ligation of these aberrant arteries, without lung resection, can restore normal pulmonary perfusion.

Area of Science:

  • Cardiovascular Surgery
  • Thoracic Surgery
  • Pulmonary Medicine

Background:

  • Intralobar pulmonary sequestration is a congenital lung malformation.
  • It involves lung tissue with abnormal systemic arterial supply and venous drainage.

Observation:

  • A 34-year-old male presented with an infected intralobar pulmonary sequestration of the left lower lobe.
  • Bilateral anomalous systemic arteries originating from the descending thoracic aorta supplied the lower lobes.
  • The right lower lobe, supplied by an aberrant artery, appeared anatomically normal without sequestered tissue.

Findings:

  • Surgical intervention included a left lower lobectomy with division of the left aberrant artery and ligation of the right anomalous artery.
  • Postoperative pulmonary perfusion scan showed normal uptake in the right lower lobe, indicating restored pulmonary arterial perfusion.

  • This case suggests that an anomalous systemic artery perfusing a normal lung can be considered a form of intralobar pulmonary sequestration.

    • Implications:

    • Aberrant systemic arteries to normal lung segments can be treated by ligation without resection.
    • This approach may preserve lung tissue and function in cases of pulmonary sequestration.
    • Further research is warranted to define the full spectrum of pulmonary sequestration and its management.
