The rare congenital anomaly of pulmonary sequestration experience and review of literature (original) (raw)

Objective Pulmonary sequestration is rare lung anomaly which had very major theories of origin. The aim of this study was to treat this rare congenital anomaly, pulmonary sequestration, which was not diagnosed of preoperatively, in our centre. Methods A retrospective analysis of 10 cases of pulmonary sequestration operated at the centre between 2000 and 2010. A review of the extralobar and intralobar types of sequestration is discussed. All patients were not diagnosed preoperatively. Results Pulmonary sequestration is found more commonly in women (6 patients). In all patients, the diagnosis was made by exploratory thoracotomy. Six patients had intralobar (one was apical) and 4 were extralobar (one apical). Lobectomy for intralobar and sequestrectomy for extralobar sequestration were performed. Conclusions Although rare, some radiological features are sufficiently suggestive of diagnosis of pulmonary sequestration. We believe that pulmonary sequestration should be considered when intrathoracic masses cannot be differentiated through invasive and non-invasive evaluation. In difficult cases methods such as aortagraphy, doppler angiography and Magnetic Resonance (MR) angiography may be used.
