Fig 1 Part of the cross section of the ascending aorta near the aortic ring. The lumen is shown on the left, and the false lumen filled with blood is shown on the right. The inset on the left is a high-power view of point a. Atherosclerotic changes in the intima are minimal. The dark dots are neutrophils. Moderate infiltration of neutrophils can be seen in the intimal side of the aortic wall. The inset on the right is the high-power view of point b. The dark dots are neutrophils. The extent of neutrophilic infiltration around the false lumen is greater than that with usual acute aortic dissections.
