Contribution à l'étude anatomique des séquestrations pulmonaires‎ : corrélations anatomo-radio-chirurgicales

Abstract : Purpose: To study the various anatomical forms of PS of early operated patients thanks to antenatal diagnosis. To discuss the embryological hypotheses from anatomical structures not modified by the inflammation. Material and methods: This retrospective study over 15 years studies all the normal and malformative anatomical elements, composing and associated in PS, from histologic, radiological, and surgical data, concerning 41 PS in 39 patients who had surgical managment at the average age of 9 months. Results: 92,2% of the PS have antenatal diagnosis. Extralobar sequestrations (ELS) and ILS have the same rate of malformative associations. We find 40% of hybrid forms in ELS and ILS, with 62,5% of preoperative diagnosis. 50% of the ELS have hilar bronchial structure. The variations in ELS and ILS could testify to different states of integration. Conclusion: ELS and ILS have the same chronologic origin. The accessory bud theory is probable in ELS. There are anatomical and histological arguments which can be in favor of an parenchymatous integration in ILS. A classification based on the primitive abnormality by accessory budding and/or atresia could allow to classify the bronchopulmonary malformations. With emergence of embolization, hybrid forms are a diagnostic challenge, neoplastic course and preneoplastic elements being described in association with CCAM.
