Pulmonary sequestration is rare and serious dysplasia, which has clinical signs of pneumonia and respiratory distress syndrome and radiological signs of polymorphic shadows. Pulmonary sequestration masses have autonomic blood supply. For confirmation of the diagnosis we use ultrasound examination, CT scan, MRI, angiopulmography and aortography.
Aim of the study: To present pathogenesis, diagnostic features and surgical treatment tactics of rare and serious pulmonary dysplasia.
Material and methods: During the period of 1979-2002, we have examined and treated 9 patients because of pulmonary sequestration. We analyzed clinical signs, results of the examination before operation, indications for operation and results of surgical treatment.
Results: Seven patients after the operation recovered, 1 patient died due to infection and cardiovascular complications. One patient is supposed to be operated on in the near future.
Conclusions: 1. Pulmonary sequestration is rare and serious bronchial - pulmonary dysplasia, which has clinical signs of pneumonia and respiratory distress syndrome and radiological signs of polymorphic shadows. 2. Pulmonary sequestrations are classified as intralobar, extralobar and extrapulmonary sequestration. 3. Pulmonary sequestration is often associated with cardiovascular dysplasias and diaphragmatic malformations. 4. Methods of examination: X-ray examination, CT scan, MRI, ultrasound examination, aortography. 5. Complications of pulmonary sequestration: pneumonia, pleuritis, necrosis of the sequestration, chylothorax, respiratory distress syndrome, hemothorax, cystic transformation, and pneumothorax. 6. Treatment - surgery or embolisation of abnormal supply vessels.
