Objective. To evaluate the effectiveness of endobronchial ultrasonography in the diagnostics of peripheral lesions of lungs. The analysis included 114 patients (69 men and 45 women) who underwent endobronchial ultrasound study using radial mini-probe (scanning frequency 20 MHz) with subsequent transbronchial biopsy of visualized lesions in lungs. Using the radial mini-probe entered into operator channel of bronchoscope, we managed to visualize pathological lesions and to perform transbronchial biopsy of lungs in 100 out of 114 cases. Total effectiveness of transbronchial biopsy of lungs was 88% (88 14 patients (20.9%) the material was not informative. Endobronchial ultrasonography is an effective method for visualization of peripheral neoplasms of the lungs. Prognostic factors of biopsy effectiveness are: size of the lesion ˃20 mm, presence of draining bronchus based on CT data, central position of mini-probe relative to the lesion.
Кey words: endobronchial ultrasonography, peripheral neoplasms of the lungs, transbronchial biopsy.
