Quantitative Pulsed Doppler Measurement of Arterial Blood Flows in Humans

Doppler flowmetry was assessed in 11 adult patients whose admission diag noses included aneurysm of the aorta or dissections. During surgery, regional blood flows of the left common carotid artery, terminal aorta, common iliac artery, external iliac artery, or common femoral artery were measured by Dop pler method and electromagnetic flowmeter. Eighty-four arterial flow determi nation were obtained from the 11 patients studied. On comparison of simultaneous electromagnetic and Doppler measurements of blood flow, an ex cellent correlation (r=0.93) was found between the two methods. The slope of the regression line was about 0.587. Regional blood flows were measured with Doppler flowmetry in another 11 patients. The values of the left common carotid, celiac, superior mesenteric, and terminal aortic flows were 255 ± 59, 618 ± 384, 670 ± 380, and 810 ± 325 mL/min, respectively. This method seems to be valua ble clinically in quantitative measurements of arterial flows in humans.
