[The hemodynamics of the intestinal arteries of the dog with special reference to the flow rate]. / Zur Hämodynamik der Intestinalarterien beim Hund unter besonderer Berücksichtigung der Flowverhältnisse.

ABSTRACT

Intestinal haemodynamics was examined invasively in 30 mongrel dogs. Beside registration of blood pressure values of the blood flow were evaluated especially. Measured flow values in the three main intestinal vessels - Truncus coeliacus, A. mesenterica superior and A. mesenterica inferior - were compared to aortal flow. Thereby the sum of intestinal arteries values was equal to intrarenal aortal flow. Two thirds of aortal flow may be expected in the portal vein. These relations make in possible to get informations about physiological intestinal circulation from single values without measurement of all intestinal vessels.
