Summary
Pulmonary sequestration, a congenital lung anomaly, can rarely be supplied by the celiac trunk. Three-dimensional computed tomography (3DCT) precisely mapped this rare aberrant artery, guiding safe surgical resection.
Area of Science:
- Cardiothoracic Surgery
- Diagnostic Imaging
- Congenital Anomalies
Background:
- Pulmonary sequestration is a congenital lung malformation characterized by non-functioning lung tissue with systemic arterial supply and lacking bronchial communication.
- Aberrant arteries typically originate from the descending thoracic aorta, but celiac trunk origins are infrequent.
- Intralobar pulmonary sequestration, especially with atypical arterial supply, presents diagnostic and surgical challenges.
Purpose of the Study:
- To report a rare case of intralobar pulmonary sequestration supplied by an artery from the celiac trunk.
- To highlight the utility of preoperative three-dimensional computed tomography (3DCT) in surgical planning for such cases.
- To demonstrate the successful application of minimally invasive thoracoscopic surgery for this condition.
Main Methods:
- Case report of a female patient diagnosed with intralobar pulmonary sequestration.
- Preoperative imaging using three-dimensional computed tomography (3DCT) to delineate the aberrant artery's origin, course, and branches.
- Surgical intervention via thoracoscopic basal segmentectomy with precise control of the aberrant artery.
Main Results:
- The aberrant artery supplying the right lower lobe sequestration originated from the celiac trunk, a rare finding.
- Preoperative 3DCT provided detailed anatomical information crucial for surgical strategy.
- Thoracoscopic segmentectomy was performed successfully, with effective haemostasis and prevention of ischemic complications.
Conclusions:
- Pulmonary sequestration supplied by the celiac trunk is an uncommon presentation requiring careful preoperative assessment.
- 3DCT is an invaluable tool for mapping aberrant vasculature, facilitating safe and precise surgical planning.
- Minimally invasive thoracoscopic approaches are feasible and effective for managing pulmonary sequestration with complex arterial supply.
