Abstract: Abstract: To establish a fine morphological structure of Kunming mice arterial ring ( Willis ring) ． Select Kunming mice by perfusion technology． Briefly infusing plasticizer about 2 ml from the left ventricle to cerebral vessel was performed，then skull bones were removed，and the structure of Willis ring was observed． This method made a fine cerebral vessel very clear and Willis ring clearly was revealed in the three-dimensional． We successfully adopted the perfusion technology to show the morphological structure of mice cerebral vessel which would play an important role for manufacturing the model of mice cerebral vessel．

Key words:

Willis ring, cerebral ischemia, plasticizer filler
