Clinical symptoms and therapy of lung separation.

This paper refers to the different terminology used in so-called lung separation/sequestration and to the standpoint of the pathologist. Theories of development are discussed. Clinical symptoms, diagnosis, indications for operation and operative technique are described, and nine cases of lung separation (six with extralobar and three with intralobar forms) tabulated analysed. Among them there is a 5-month-old female infant with extralobar lung separation in the right hemithorax resulting in recurrent pleural effusions with severe respiratory insufficiency. There was evidence of aeration in the pathohistological preparation. Pleural effusion and the origin of the aeration in the separated lung are discussed.
