[Pathophysiology, clinical aspects and course of bullous emphysema (author's transl)]

Bullous emphysema (progressive lung dystrophy) is a disease of advanced age and over 90% of the patients are men. The bullous changes in the l-ng perferentially affect the apical fields and the left lower area. Bronchographic visualization is in this case not possible. The disease runs a progressive course. Valvular stenoses of the bronchi and especially of the bronchioles in various types of primary pulmonary disease are of considerable importance etiologically.
