METHOD FOR ASSESSING THE PROBABILITY OF INTRA-ABDOMINAL HYPERTENSION IN PATIENTS WITH RETROPERITONEAL HEMATOMA Russian patent published in 2019 - IPC A61B8/06 A61B5/103 A61B5/107 G16H50/30 

FIELD: medicine.

SUBSTANCE: invention refers to medicine, namely to ultrasonic diagnostics, and can be used for assessing the probability of intra-abdominal hypertension in patients with retroperitoneal hematoma. Ultrasound examination is carried out. Ultrasound criteria are determined, each of which is assigned a point score upon detection. If observing a decrease in the transverse dimension of the inferior vena cava, 7 points are assigned. If observing a change in the shape of the inferior cava vein cross-section to a slit-like one with loss of shape variations related to the respiratory act, 19 points are assigned. If the portal vein lumen is decreased with the lumen change associated with the respiratory act, 8 points are assigned. If the index of the inferior vena cava is less than 50 %, 3 points are assigned. When compressing the kidneys on the side of retroperitoneal hematoma 4 points are assigned, while the kidney compression on the side without the retroperitoneal hematoma – 10 points. If the resistive index (RI) in the renal artery is more than 0.75, 5 points are assigned. If the peak systolic blood flow velocity in the renal artery is less than 63 cm/s, 17 points are assigned. Scoring of the revealed criteria is summed up and the presence of the abdominal hypertension is determined by the total score. If score is 29 or less, the low probability is stated; the average probability is determined at 30–55 points, while the high probability is determined at 56 points or more.

EFFECT: method enables simple and affordable assessment of intra-abdominal hypertension probabilities in the patients with retroperitoneal hematoma by determining ultrasonic signs.
