[Parasternal mediastinopleuroscopy in the diagnosis of malignant neoplasms of the anterior mediastinum].

The authors suggest a clinical procedure of parasternal mediastinopleuroscopy which assures intercostal examination, instrumental palpation and biopsy of neoplasms of the anterior mediastinum without causing considerable trauma. The procedure makes it possible to assess operability and to determine optimal access for surgical removal of tumor. The procedure was used in clinic in 35 cases; in 23 of them, intervention was limited to biopsy, while 12 cases underwent radical surgery.
