Pulmonary sequestration: 17-year experience at UCLA

Area of Science:

• Thoracic Surgery
• Pediatric Surgery
• Diagnostic Imaging

Background:

• Pulmonary sequestration is a congenital lung malformation characterized by abnormal lung tissue with anomalous vasculature.
• This condition can present with diverse symptoms, including recurrent pneumonia and respiratory distress, affecting both pediatric and adult populations.
• Accurate diagnosis is crucial for effective management and surgical planning.

Purpose of the Study:

• To review the clinical presentation, diagnostic methods, and surgical outcomes of pulmonary sequestration cases treated at a single institution.
• To evaluate the efficacy of various imaging modalities in diagnosing pulmonary sequestration.
• To emphasize the importance of surgical intervention for this anomaly.

Main Methods:

• Retrospective review of 10 patients diagnosed with pulmonary sequestration between 1975 and 1992.
• Analysis of clinical data, including age, sex, symptoms, and presenting conditions.
• Evaluation of diagnostic imaging results (chest radiography, computed tomography, angiography, ultrasonography, MRI) and surgical findings.

Main Results:

• Ten patients (7 female, 3 male) with intralobar and extralobar pulmonary sequestration were treated.
• Symptoms varied, with recurrent pneumonia and respiratory distress being most common.
• All patients underwent successful thoracotomy and lobectomy with no operative mortality; nine had excellent long-term outcomes.
• Chest radiography and CT scans were the most informative imaging modalities.

Conclusions:

• Pulmonary sequestration is an uncommon but treatable condition.
• Surgical resection through thoracotomy offers excellent results for patients with pulmonary sequestration.
• Awareness of anomalous vascular connections is vital for successful surgical management by thoracic surgeons.
