In order to investigate the influence on the blood flow direction and pattern at the arterial bifurcation, the mesenteric arterioles of 19 SD rats were observed under the OLYMPUS BH2 surgical microscope. After the rats were anesthetized and the body temperature was kept at 37℃ to 38℃, the mesenteric membrane wasexposed and the pattern and direction of the blood flow of the arterioles whichbifurcated at angle of 45±5°, 90±5° and 135±5° were observed. Results showed that the deformation of RBCs made them easy to adapt to the intravascular geometry and pass by fluently without sticking. It was implied that the alteration in arterial flow direction did not cause turbulance at the bifurcation site, and this in return suggested that in end-to-side anastomosis of small arteries,the flow volume would not be reduced and the chance of thrombosis would not be increased.
