ULTRASONIC DIAGNOSTIC TECHNIQUE FOR SURGICAL COMPLICATIONS Russian patent published in 2014 - IPC A61B8/08 A61B8/06 

FIELD: medicine.

SUBSTANCE: B-mode examination is used to determine indirect inflammation signs: subcutaneous fat thickness, oedema, infiltrate, fluid collection. The local venous blood circulation in the veins of a surface layer of the abdominal walls. A vascular diameter is measured by Colour Doppler Imaging and Energy Doppler Imaging. Colour duplex scanning is used to measure qualitative and quantitative local blood circulation values: respiratory phase of the blood circulation, Vmax cm/s not less than in 3 veins of the surface layer of the abdominal wall with calculating mean Vmax. The operated and intact ultrasonic patterns are compared. The intact area is an abdominal region 10 cm and more from the wound. If observing one or more indirect inflammation signs, the respiratory phase of the blood circulation, an increase of the vascular diameter by 50% and more, an increase of mean Vmax by 30% and more, the presence of surgical infections at the stage of inflammatory infiltrate is diagnosed. If observing one or more indirect inflammation signs, an increase of the vascular diameter by 50% and more, an increase of mean Vmax by 35% and more, the absence of the respiratory phase of the blood circulation, the presence of a surgical infection at the stage of wound abscess is diagnosed.

EFFECT: technique enables more qualitative and accurate diagnosis of the presence of the surgical infection and the stage of the developing process ensured by the additional determination of varying qualitative and quantitative values of the local venous blood circulation.
