FIELD: medicine.
SUBSTANCE: invention refers to medicine, namely to angiology, vascular surgery, roentgenology, and can be used for diagnosing ischemic proctosigmoiditis in postoperative patients on an abdominal aorta. Colonic blood flow velocity is determined. Blood flow velocity in the rectosigmoid colon wall is determined by perfusion computed tomography before and after the operation. If observing clinical signs of proctosigmoiditis and reducing blood flow velocity, ischemic proctosigmoiditis is diagnosed.
EFFECT: method provides differential diagnosis of ischemic proctosigmoiditis by non-invasive quantitative assessment of blood flow velocity of all layers of rectosigmoid colon wall.
