METHOD OF DESCENDED INTESTINE BLOOD SUPPLY ASSESSMENT IN PATIENTS WITH COLORECTAL CANCER BY INTRAOPERATIVE TRIPLEX SCANNING Russian patent published in 2010 - IPC A61B8/06 A61B8/08 

FIELD: medicine.

SUBSTANCE: invention refers to medicine, namely to ultrasonic diagnostics, and aims at the descended intestine blood supply assessment in the patients with colorectal cancer (CRC) by the intraoperative triplex scanning. It involves an intraoperative Doppler ultrasound of the inferior mesenteric artery (IMA). For this purpose, a sterile sensor is placed in an operative wound on the abdominal aorta in a projection of the IMA outlet 2-3 cm above bifurcation of the aorta in the mesenteric width, and an aorta cross-section is displayed. A duplex IMA scanning follows with the use of colour Doppler imaging and pulsed wave Doppler, the qualitative indices are measured: Doppler curve shape, Doppler spectrum type, as well as blood flow values determined in health in definite ranges wherein the IMA is described as an artery of high peripheric resistance, while blood supply of the descended transplant is considered as good; when observing quantitative discrepancies, the absence of the IMA trunk is stated, while blood supply of the descended transplant is considered as poor.

EFFECT: method allows determining intraoperative qualitative and quantitative values of the IMA blood flow in the CRC patients for operative aid planning.
