METHOD FOR DIFFERENTIAL DIAGNOSTICS OF FOCAL FORMATIONS ON MEDIASTINAL PLEURA IN CASE OF PLEURAL EFFUSION

摘要

FIELD: medicine.;SUBSTANCE: ultrasound scanning of the pleural cavity and mediastinal pleura in the vertical position of the patient is performed at the level of the heart ventricles. A convection sensor with a frequency of 3.5-5.0 MHz is used. Longitudinal scanning along the parasternal line is performed from intercostal space IV and V perpendicular to the thoracic wall. The sensor is laterally displaced to the midclavicular line with scan plane direction towards the heart. In the presence of oval or elongated mediastinal pleuras formations of form with a lobed middle-echo structure on the heart surface, which perform pulse movements during heartbeat, fatty suspensions are diagnosed. In the presence of flattened or rounded formations with a homogeneous hypoechoic structure not performing pulse movements during heartbeat, metastases are diagnosed.;EFFECT: method increases the accuracy of ultrasound diagnostics due to a possibility of targeted examination of the mediastinal pleura.;5 dwg, 2 ex
