Spectrum of pulmonary sequestration

M W Flye, M Conley, D Silver

    The Annals of Thoracic Surgery
    |November 1, 1976
    PubMed
    Summary

    Bronchopulmonary sequestration, a rare lung condition, presents varied symptoms from asymptomatic to respiratory and cardiovascular issues. Diagnosis via arteriography guides surgical treatment, with resection for intralobar and excision for extralobar types.

    Area of Science:

    • Pulmonary Medicine
    • Thoracic Surgery
    • Pediatric Cardiology

    Background:

    • Bronchopulmonary sequestration (BPS) is a congenital lung malformation.
    • It involves lung tissue with an abnormal blood supply, typically from systemic arteries.
    • BPS can lead to significant respiratory and cardiovascular complications.

    Purpose of the Study:

    • To describe the clinical presentation, diagnostic methods, and treatment outcomes of bronchopulmonary sequestration.
    • To analyze the spectrum of symptoms and age-related manifestations of BPS.
    • To evaluate surgical approaches for intralobar and extralobar sequestration.

    Main Methods:

    • Retrospective review of 17 patients diagnosed with bronchopulmonary sequestration.
    • Analysis of patient age, sequestration type (intralobar vs. extralobar), clinical symptoms, diagnostic modalities, and surgical interventions.
    • Review of diagnostic imaging, including chest roentgenograms and arteriography.

    Main Results:

    • 17 patients diagnosed with BPS, aged newborn to 64 years.
    • 14 intralobar and 3 extralobar cases identified.
    • Symptom patterns included asymptomatic (6), respiratory (8), and cardiovascular (3) presentations.
    • Cardiovascular symptoms were more common in neonates, often with a respiratory component.
    • Older patients typically presented with recurrent pulmonary infections or incidental radiographic findings.
    • Arteriography was the definitive diagnostic study.
    • Surgical treatment involved segmental resection or lobectomy for intralobar BPS and simple excision for extralobar BPS.

    Conclusions:

    • Bronchopulmonary sequestration exhibits a wide range of clinical presentations depending on age and type.
    • Early diagnosis and appropriate surgical management are crucial for favorable outcomes.
    • Arteriography remains essential for definitive diagnosis, guiding surgical planning.
    • Treatment strategies should be tailored to the specific type and extent of the sequestration.
