[Ultrasonic technologies in diagnosis and surgery planning in patients with nodular pathologies of the thyroid gland]

Twenty patients of the control group without pathology of the thyroid gland were examined for development of the method of 3D-ultrasonic reconstruction and 3D-angiography. The study group consisted of 74 patients with nodular pathologies of the thyroid gland, 53 of them underwent surgery. Ultrasonic data was compared with results of clinical and laboratory studies, puncture biopsy and intraoperative data. Three-dimensional ultrasonic pictures permitted to detect spatial orientation of the nodes relative to lobes and segments of the thyroid gland, vascular structures, to evaluate character of nodes vascularization, to analyze nature and invasiveness of the tumor. Based on these data optimal variant of surgery was chosen. In 12 cases virtual modeling of surgeries with 3D-echography and ultrasonic angiography was performed. These methods permit to choose optimal variant of surgery and make possible prediction and prevention of complications.
