The aim of the work: to study the echostructure, state and features of vascular perfusion of the thyroid residue of the thyroid gland after surgery over time and to determine the clinical significance of the CDC and ED.
Materials and Methods. The thyroid balance was examined in 86 patients, after the performed organ-preserving thyroid surgeries on the 7th day, 1 month and 1 year after the surgeries using ultrasound device the Esaote MyLabX6 (Italy) and HDI 5000 (ATL USA) with a linear broadband L12-5MHz sensor. The size and structural changes in the tissue left were determined. The blood supply to the tissue and its membranes was studied by determining quantitative characteristics – resistance index (RІ), maximum systolic velocity (MSS), end diastolic velocity (EDS) and energy Doppler sonography (ED).
Results and Discussion. An increase in the volume of a lobe or stump is accompanied by a change in their type of structure, from flat (without a shape) areas they become sheet-like and conical, and the growth rate is a certain percentage of changes in the type of structure in 37 (43 %) patients on day 7 and already 66 (77 %) – after 1 year. The CDC indicates that the blood supply to the thyroid residue passes mainly along the periphery at the sites of newly created messages.
