METHOD OF LATE THROMBOTIC REOCCLUSION PROGNOSIS Russian patent published in 2012 - IPC A61B10/00 G01N1/28 

FIELD: medicine.

SUBSTANCE: invention refers to medicine, particularly to cardiovascular surgery. To forecast late thrombotic reocclusions, biopsy of abdominal aorta portion from the area of proximal anastomosis is performed. Further histological research is performed with morphometric changes of the following parameters: macrophage presence, intima state, inclusion properties, muscular element state. Probability of late thrombotic reocclusions (W) is determined by the formula W=A×B×C×D×100 where A is probability of thrombotic reocclusions for patients with various macrophage presence levels; B is probability of thrombotic reocclusions for patients with various intima defect levels; C is probability of thrombotic reocclusions for patients with various inclusions in vascular walls; D is probability of thrombotic reocclusions for patients with various state of vascular wall muscle elements. For W within 1.1 to 5% high risk of late thrombotic reocclusions is diagnosed, for W within 0 to 1% low risk of late thrombotic reocclusions is diagnosed.

EFFECT: increased accuracy of late thrombotic reocclusion forecast in post-operation period due to involvement of morphological parameters characterising disease combativeness in operation area.
