FEATURES OF FINE-NEEDLE VACUUM ASPIRATION BIOPSY UNDER ULTRASOUND CONTROL IN PATIENTS WITH FOCAL THYROID PATHOLOGY

One of the main diagnostic methods used in diseases of the thyroid gland is ultrasound examination of the thyroid gland. Due to its availability and noninvasiveness, high information content, ultrasound is an extremely effective method of differential diagnosis of thyroid pathology. Despite the sufficient Arsenal of diagnostic methods that allows us to suspect nodal changes in the thyroid gland, a cytological biopsy is the “golden standard” in diagnostic algorithms. The use of ultrasound control methods for performing minimally invasive interventions significantly facilitates manipulation and reduces the risk of possible complications, but does not exclude the possibility of their occurrence. In connection with all the above, there is an idea to create a device that helps to facilitate the performance of a fine-needle aspiration biopsy to a specialist, reduce the risk of possible complications and increase the information content. In the Problem scientific research laboratory «Diagnostic studies and minimally invasive technologies” of the Smolensk state medical University developed a device to increase the efficiency and informational content of fine-needle aspiration biopsy under the control of ultrasound navigation in patients with nodular formations of the thyroid gland. 26 (9.5%) patients were performed fine-needle vacuum aspiration biopsy using the created device, thanks to which 18 (6.6%) patients were found to have adenomatous formation, changes in the type of subacute thyroiditis were found in 5 (1.8%) patients, and 3 (1.09%) cases of follicular neoplasia. In cases where a higher discharge is necessary for the collection of cytological material, and the developed device allows you to create conditions that increase the information content and facilitate the procedure, in addition, it is possible to perform the procedure by one specialist, which reduces the workload of several specialists in the Department dealing with minimally invasive interventions.
