[Diagnosis and treatment of neoplastic and cystic formations of the mediastinum].

The article analyses problems of the diagnosis and surgical and complex treatment of 56 patients with neoplastic and cystic structures in the mediastinum. In the group of 56 patients 28 had neoplastic diseases of the mediastinum, in 11 of them the tumors were malignant. According to the data presented, postoperative mortality in mediastinal cysts was zero. In mediastinal tumors the preoperative diagnosis was authentically established in 11 of 28 patients (39.3%), postoperative mortality was 7%. An original method for hemostasis in bleeding from the seat of the mediastinal tumor is described. The survival of patients with malignant mediastinal structures treated by partial resection of the tumor, radiotherapy and polychemotherapy varies from 6 months to 4 years, which allows the conclusion that wider application of complex treatment is expedient.
