For debate Pulmonary sequestration and related congenital bronchopulmonary -

No satisfactory classification for congenital anomalies of the bronchopulmonary airway and related vasculature has yet been described. An attempt was made to overcome this problem by expanding the concept of "sequestration" (originally intended as a single entity) to include a range of bronchovascular anomalies. This has failed to gain universal acceptance and led us to develop an alternative nomenclature and classification based on simple anatomical description. This paper discusses the background to the new approach while a companion paper applies it to our own cases reviewed during five years.
