Method of differential diagnostics of mammary gland and soft tissue growths

FIELD: medicine.

SUBSTANCE: ultrasound is performed with intravenous contrast enhancement using the high resolution mode, the microbubble tracing mode MTI, the MI mechanical index value equal to 0.06, with the focus setting under the growth. The vascularization and perfusion of the growth are evaluated using kinetic curves and contrasting patterns. There are kinetic curves of I, II, III types and the following contrasting patterns - annular, annular with the parietal component, dendritic, spicular, spiral, wherein: I type of kinetic curve - gradual linear increase in contrast enhancement of the growth during the study, II type - linear increase in contrast enhancement of the growth with the subsequent plateau phase, III type - peak of the contrast enhancement of the growth, which occurs at the first seconds, then a rapid subsequent decrease in the enhancement. The annular pattern - the vascular neoplasm pattern resembles a ring, is characterized by single microvessels with the same diametre and uniform distribution along the periphery of the growth, the annular pattern with the parietal component - the vascular pattern resembles a ring with the parietal component, is characterized by single microvessels along the periphery of the growth and uneven parietal distribution, the dendritic pattern - the vascular pattern resembles twigs of a tree, is characterized by multiple microvessels with the same diametre and uniform distribution in the structure of the growth, the spicular pattern is characterized by multiple microvessels along the periphery of the growth, which have a chaotic, spicular distribution; the spiral pattern - the vascular pattern resembels spirals with different diametres, is characterized by multiple microvessels with different diametre and uneven asymmetrical distribution. When visualizing the annular pattern or dendritic pattern in combination with a kinetic curve of types I or II or the annular pattern with a parietal component in combination with a kinetic curve of I type, a benign growth is diagnosed. When visualizing the annular pattern with the parietal component, or the spicular pattern, or the spiral pattern, in combination with the kinetic curve of III type, malignant growth is diagnosed.

EFFECT: increased accuracy of differential diagnostics of mammary and soft tissue growths by creating new evaluation criteria of vascularization and perfusion of growth using kinetic curves of enhancement-time and contrasting patterns.

SUBSTANCE: method for detecting the burn wound granulation readiness for autografting involves the granulation microcirculation by laser Doppler flowmetry to calculate an average microcirculation (M, p.u.). That is combined with combining a granulation microcirculation effectiveness index (MEI). If the MEI is more than 1.6, and M is more than 3 p.u. the reparative ability of the burn wound granulation is considered to be preserved, and the granulation appears to be ready for autodermoplasty. If MEI is less than 1.6 regardless of the value M, the reparative ability of the burn wound granulation is considered to be diminished, the wound requires additional wound cleansing and granulation incision.

EFFECT: method enables providing the higher diagnostic effectiveness of the reparative ability of the tissues, selecting the autodermoplasty time, reducing the rate of transplant rejections and cutting the treatment costs and reducing the length of staying in hospital.

SUBSTANCE: microcirculation is assessed by laser Doppler flowmetry using combined functional tests - thermal postural leg test and thermal postural arm test. Both tests involve recording a microcirculation index. The derived data are saved. An average basic microcirculation from the 10th to 110th seconds is evaluated for the leg and arm tests according to the provided formulas. That is followed by calculating an average relative microcirculation Irel1 and Irel2 during the functional leg exposure according to the presented formulas. If any of the two values Irel1, Irel2 is below standard - Irel1<3.7; Irel2<3.5, the presence of microcirculatory disorders is stated in the person being tested.

EFFECT: method is accurate, simple, enables immediately detecting systemic microcirculatory disorders in the patients suffering carbohydrate metabolism disorders on the basis of available diagnostic tests and measured microcirculation parameters; using the combined functional tests involves most regulatory mechanisms that provides obtaining the reliable microcirculation information from the patients of this category.

Next, when applying compression tests, blood circulation parameters variations are recorded in distal segment of the subclavian artery with arterial blood pressure being concurrently measured. Three degrees of superior thorax aperture syndrome severity are diagnosed depending on reduction of linear blood circulation velocity and arterial blood pressure compared to their initial values. Mild one takes place when linear blood circulation velocity reduction reaches 40% and arterial blood pressure 20% of initial level, moderate one when linear blood circulation velocity reduction reaches 70% and arterial blood pressure 50% and heavy one when linear blood circulation velocity reduction is greater than 70% of initial level and arterial blood pressure is greater than 50% to the extent of no blood circulation manifestation being observed in the subclavian artery.

EFFECT: high accuracy of diagnosis.
