Background: Due to its availability, high information content and harmlessness, ultrasound is an extremely effective method of differential diagnosis of thyroid pathology. Despite the sufficient arsenal of diagnostic methods, thyroid biopsy with cytological examination is the «gold» standard in diagnostic algorithms. Most often, fine — needle aspiration biopsy is carried out using disposable syringes of different capacities (5, 10, 20 ml3). The procedure is performed in most cases according to the «Free hand» method, this leads to several problems associated with the peculiarity of the study, primarily with the low vacuum created in the syringe and insufficient collection of cytological material, as well as insufficient practical experience for a novice specialist.Aim: Determination of the range of the possibility of using vacuum aspiration fine needle biopsy under the control of ultrasound navigation in patients with focal thyroid pathology.Materials and methods: On the basis of the Problem Research Laboratory «Diagnostic studies and minimally invasive technologies» of the Smolensk State Medical University, a device for vacuum fine — needle aspiration biopsy was developed. In the period 2019–2020, 780 vacuum fine — needle aspiration biopsy was performed under the control of ultrasound navigation in patients with thyroid nodules. The level of vacuum in the syringe during sampling of the material was — 0,5 bar (- 50 kPa).Results: A comparative analysis of the cytological results obtained with the help of vacuum fine — needle aspiration biopsy and the «Free hand» method shows a decrease in obtaining the category of Bethesda 1 by 3.3% and Bethesda 3 by 10.2%.Conclusion: This indicates the effectiveness and in formativeness of the use of vacuum fine — needle aspiration biopsy in patients with focal thyroid pathology in comparison with the standard «Free hand» method, as well as with vacuum fine — needle aspiration biopsy due to constant visual monitoring and the lack of movement of the syringe piston to create a discharge when taking cytological material, the probability of needle deviation from the biopsy zone is reduced, which increases the effectiveness of the study and facilitates the work of a novice specialist.

Different methods for preoperative diagnosis of nodular euthyroid formations of the thyroid gland are compared. The sensitivity and specificity of ultrasonic examination (based on the study of the semeiotics of nodular formations of the thyroid), fine-needle aspiration biopsy (under palpation and ultrasonic control), and complex diagnosis (simultaneous assessment of ultrasonic semeiotics of the nodular formation and controlled biopsy under ultrasonic control followed by cytological examination of puncture biopsy specimens) are assessed. With this aim in view, 342 patients with nodular euthyroid formations were examine^ in 1994-1996. Benign nodular formations were detected in 316 (92.4%)) and thyroid cancer in 26 (7.6%o) patients. In the group with benign formations, colloid goiter was diagnosed in 204 (59.7%), follicular-cell adenomas in 78 (22.8%)), and hypertrophic autoimmune thyroiditis in 34 (9.9%) cases. The authors consider that ultrasonic examination combined with fine-needle aspiration biopsy is the most available, safe, and highly effective complex for the diagnosis of nodular euthyroid formations at the preoperative stage. Complex preoperative ultrasonic examination with fine-needle biopsy help single out the group with suspected malignant involvement of the thyroid with a high probability. Use of this complex and intraoperative ultrasonic examination correctly identified the type of thyroid involvement and its morphology in 92.4%o of cases, and thus helped choose adequate volume of intervention.

ABSTRACT Cytodiagnostic fine needle aspiration biopsy specimens from toxic goitres were studied for signs of lymphoid infiltration. Comparison with histological sections of specimens obtained by surgery showed that an excess of lymphoid cells in the aspirate smears corresponded to a large number of lymphoid foci in these sections. Excess of lymphoid cells in the fine needle aspirates was also positively correlated with the occurrence of circulating thyroid antibodies against thyroglobulin and/or cytoplasmic antigen, but not with the presence of the long-acting thyroid stimulating factor, LATS. It also varied with age in that it was most common in the youngest patients and in patients between 40–55 years, while lymphoid infiltration was seldom seen in patients over 55 years. A finding of practical clinical interest was that in toxic goitres with cytological signs of lymphoid infiltration hyperthyroidism had less tendency to recur after treatment with thiocarbamide drugs than in those without such signs.
