[Therapeutic procedures in the middle lobe syndrome].

From study of the case records of 113 patients with isolated affection of the middle lobe or lingular segments of the left lung the authors believe that nonspecific inflammatory diseases of the lungs are the most frequent cause of the development of the syndrome. Tomography and bronchography of the involved lung play the principal role in the diagnosis of the middle-lung syndrome. The etiological factor is verified by the findings of tracheobronchoscopy. The authors consider surgery to be the main method of treatment of the middle-lobe syndrome or syndrome of the lingular segments.
