This paper describes the flow visualization around the anterior communicating artery and the dynamic pressure at the apex along the medial wall. The anterior communicating artery composing the circle of Willis is one of the predilection sites where cerebral aneurysm occurs frequently. The flow field around the anterior communicating artery is simulated by two confluent tubes joined at on angle of 60 degrees, two parallel bifurcating tubes, and a junctional tube, bypass, connecting the four tubes. The flow field around the apex where cerebral aneurysm is apt to occur is vsiualized using a laser sheet. In particular the dynamic pressure to the apex at one confluent tube with a high flow rate is estimated, and the relationship between the dynamic pressure and the generation of aneurysm is discussed physiologically.
