Clinical Manifestations Of Pulmonary Sequestration:2Cases Report And Literature Review

ObjectivesTo investigate the clinical presentations and features of pulmonary sequestration, and therefore to improve the diagnostic accuracy.Methods2patients diagnosed as pulmonary sequestration in Shandong provincial hospital East from Jun,2011to Dec,2011were reviewed and analyzed. After preparation of clinical information materials of these patients, we analyzed the clinical characteristics, imaging, treatment and prognosis retrospectively, and the literature were reviewed as well.ResultBoth of the2cases were diagnosed with intralobar sequestration (ILS); The spiral CT of the ILS patients demonstrated thin shadows or massive consolidation with or without cystiform alterations and air bronchogram, mostly located at the left lower lung, and often with finding of aberrant feeding artery from systemic artery. With the extralobar sequestration (ELS) case, a well-defined cystic mass and aberrant feeding artery can be found in CT scan. In fibrobronchoscopy, no other abnormality can be found both in ILS and ELS cases except light congestion of bronchial mucosa.2cases of ILS underwent lobectomy with excellent result.ConclusionsIn pulmonary sequestration, ILS occurs more frequently than ELS, the common symptoms are recurrent respiratory infection and hemoptysis. In ELS patients, usually there is no complaint. Chest spiral CT scan and three-dimensional reconstruction of blood vessels are usually helpful for the diagnosis. Once PS is diagnosed, surgery is suggested, and the common treatment is resection of the sequestered lobe and the clinical outcome is favorable.
