Pulmonary sequestration: a review of 12 cases.

A review of patients over a twenty-three year period with a diagnosis of pulmonary sequestration was undertaken. Of the twelve patients with this diagnosis, ten had intralobar sequestrations, and two had the extralobar variety. The most common presenting complaint, in six of the patients, was an unresolving localised chest infection. All had abnormal plain chest radiographs. There was a high incidence of an anomalous vascular supply, and aortography was useful in investigation. Operative management consisted of segmentectomy or lobectomy for the intralobar form and simple excision for the extralobar form with good results.
