[Ultrasonic technologies in diagnosis and treatment of patients with surgical diseases of lungs and pleura].

The results of complex examination and treatment of 376 patients with different diseases of the lungs and pleura were analyzed. High-frequency ultrasound was used in 256 patients for diagnosis of lungs and pleura surgical diseases, 412 ultrasonic examinations were performed. Intraoperative treatment of pleura with low-frequency ultrasound was carried out 134 times for prophylaxis and treatment of acute postoperative pleura empyema in 120 patients operated on for malignant tumors and chronic purulent diseases of the lungs. High efficacy of high-frequency ultrasound for diagnosis of pleura empyema, diffuse and encapsulated pleurisy is demonstrated. Ultrasound-assisted pleural punctures an transthoracic aspiration biopsies permit to avoid complications. Ultrasonic examination of the lungs during surgery in patient suspected of lung cancer permits to study tumor structure. Treatment of pleura with low-frequency ultrasound and combination of this method with photodynamic therapy promote reliable sanation of pleural cavity. Limited rethoracotomy and treatment of pleura with low-frequency ultrasound is the method of choice in the treatment of acute postoperative empyema when there is no effect of conservative treatment.
