Secuestros pulmonares: presentación de 8 casos / Pulmonary sequestrations: Presentation of eight cases

Introducción El secuestro pulmonar es un parénquima pulmonar patológico aislado y con vascularización arterial propia y es infrecuente. Objetivos Estudio descriptivo-retrospectivo de pacientes del Hospital Universitario La Princesa. Material y métodos Se analizan las características de pacientes del Servicio de Cirugía Torácica del Hospital Universitario La Princesa entre 1996-2008.ResultadosSe intervino a 8 pacientes con confirmación anatomopatológica, 5 eran mujeres. La infección respiratoria apareció en 7 pacientes, con afectación del lóbulo inferior derecho en 4 de ellos. La variante intralobular se diagnosticó en 7 enfermos. La vascularización provenía de la aorta torácica en 5 casos. La vía de abordaje fue la toracotomía posterolateral y se practicaron lobectomías en 5 pacientes. No hubo morbimortalidad.Conclusión1. Es una anomalía congénita infrecuente. 2. En nuestra serie, la frecuencia es mayor en mujeres en los lóbulos inferiores y es similar en ambos hemitórax. 3. La clínica más frecuente fue la infección respiratoria de repetición. 4. El diagnóstico se realizó mediante pruebas de imagen (AU)

Introduction Lung sequestration is a pathologically isolated pulmonary parenchyma, with its own arterial vascularisation. Aims A descriptive-retrospective study of patients of the La Princesa University Hospital, Madrid. Material and Methods The characteristics of patients admitted to the La Princesa University Hospital Thoracic Surgery Unit during 1996–2008, were analysed. Results Of the 500 patients, 8 had histopathology confirmation, of which 5 were women. There was respiratory infection in 7 patients, with 4 in the lower right lobe. The intralobar variant was diagnosed in 7 patients. The systemic vascularisation came from the thoracic aorta in five cases. A standard posterolateral thoracotomy with lobectomy was performed in 5 patients. There was no morbidity or mortality. It was more common in women, in lower lobes and similar in both hemithorax; 3. The most common clinical symptom was the respiratory infection; 4. The diagnosis was made with imaging tests (AU)
