METHOD FOR X-RAY EXAMINATION OF PORTOCAVAL SYSTEM OF INDIVIDUAL'S RECTUM EXPERIMENTALLY Russian patent published in 2015 - IPC G09B23/28 A61B6/00 A61K49/04 

FIELD: medicine.

SUBSTANCE: X-ray examination of a venous bed of an individual's rectum involves using 76% urografin. The inferior mesenteric vein stem and iliac vascular bundles from both sides are approached. They are catheterised and prepared by washing in 10% ammonia and distilled water. Before preparation, the inferior mesenteric vein is detected by a method of visualisation of the portal vein system. A green solution of brilliant green is inserted into its stem. The final stage is a direct X-contrast examination by fixed 12P9 Armobil-9 X-ray apparatus. 3 series of images are done. The first comparison X-ray represents plan radiography in a frontal projection of the small pelvis. The second X-ray is plan radiography in a frontal projection of the small pelvis with tight filling of the prepared bed of the rectal portal system with X-ray contrast 76% urografin. The third X-ray is plan radiography in a frontal projection of the small pelvis with tight filling of the internal iliac veins from both sides in a combination with X-ray contrast 76% urografin.

EFFECT: method provides optimising the X-ray examination of the individual's rectal veins, visualising the vascular system adequately, ensuring the information concerning special characteristics of the vascular organometry, enables detecting the portocaval anastomosis by the optimum preparation of the vascular system, using urografin as the contrast substance and implementing the developed procedure of the X-ray examination.
