Pulmonary sequestration: A single-institutional series composed of 27 cases

Abstract

Large series about pulmonary sequestration from a single institute are rare in the literature. In this study, we aimed to evaluate diagnosis, treatment, and outcomes of pulmonary sequestration in a single institute. Records of patients with pulmonary sequestration between January 1982 and January 2006 were reviewed retrospectively. Age, sex, symptoms, diagnostic procedures, operative findings, operative techniques, postoperative complications, and follow-up results were evaluated. Twenty-seven patients, 17 male and 10 female, with an average age of 23.3 were operated on for pulmonary sequestration. Twenty patients had preoperative symptoms including recurrent pneumonia attacks, chest pain, hemoptysis, and shortness of breath. Chest radiography, thoracic computed tomography, aortography, magnetic resonance imaging, and bronchoscopy were used as diagnostic methods. Of the cases, 19 (70%) were intralobar pulmonary sequestration and 8 (30%) were extralobar pulmonary sequestration. Surgical procedures were lower lobectomy in 18 and segmentectomy in 1 of the patients with intralobar pulmonary sequestration and simple mass excision in all of those with extralobar pulmonary sequestration. Postoperative histopathologic examinations excluded any other alternative diagnosis. Furthermore, it detected an aspergilloma ball in 1 of the intralobar pulmonary sequestration specimens. Two patients had a postoperative complication (prolonged air leak in 1 patient and empyema in the other). During the follow-up period (mean 2.3 years), none of the patients presented a problem. No mortality was encountered. Owing to the potentially severe complications they can cause, pulmonary sequestrations should be removed whenever they are diagnosed. Since careful dissection provides sufficient surgical comfort, preoperative identification of the aberrant vessels is not a rule for the success of the operation.
