Pulmonary sequestration in children: a twenty-five year experience
Insights
Pulmonary sequestration is a rare congenital lung malformation where nonfunctioning lung tissue lacks normal airway connection. Arteriography is crucial for diagnosis and locating abnormal blood vessels before surgery.
Area of Science:
- Pediatric Surgery
- Thoracic Surgery
- Congenital Malformations
Background:
- Pulmonary sequestration is a congenital lung anomaly characterized by nonfunctioning lung tissue.
- This sequestered tissue lacks normal communication with the tracheobronchial tree.
- It often receives an anomalous systemic blood supply.
Purpose of the Study:
- To analyze cases of pulmonary sequestration in children.
- To highlight diagnostic challenges and the role of arteriography.
- To emphasize the importance of preoperative localization of aberrant vessels.
Main Methods:
- Retrospective review of 15 pediatric cases (11 boys, 4 girls) aged 1 day to 14 years.
- Analysis of diagnostic methods including roentgenography and arteriography.
- Surgical exploration as a diagnostic and therapeutic approach.
Main Results:
- Ten cases of extralobar and five of intralobar pulmonary sequestration were identified.
- Chest roentgenography suggested the diagnosis but was not conclusive.
- Arteriography provided definitive diagnosis and crucial preoperative localization of anomalous vessels.
Conclusions:
- Pulmonary sequestration requires definitive diagnosis through arteriography and/or surgical exploration.
- Arteriography is strongly advocated for both diagnostic confirmation and precise localization of aberrant vasculature.
- Accurate preoperative localization by arteriography is vital for surgical planning and minimizing operative risks.
Abstract:
Pulmonary sequestration occurs when some disturbance produces a cystic mass of nonfunctioning lung tissue which lacks normal communication with the tracheobronchial tree. In most cases the sequestered pulmonary tissue receives its blood supply from anomalous systemic vessels. This paper considers 15 children, 11 boys and four girls, ranging in age from one day to 14 years, with ten extralobar sequestrations and five intralobar pulmonary sequestrations. Although roentgenographic examination of the chest may suggest the diagnosis, conclusive diagnosis can only be obtained by arteriography and/or surgical exploration. Arteriography is strongly advocated in all cases, not only for its diagnostic value, but for its preoperative localization of the aberrant blood vessels that are the major technical concern to the surgeon.
