1 Dissection

Strictly speaking, my problem is not an aortic aneurysm, it is more correctly an aortic dissection. What this means is that the walls of the aorta have ruptured, but not all the way through. Think of the aorta as concentric hose-pipes.


My simplified diagram shows the blood bursting through the inner wall (intima). At the outer wall it turns, rips down between the walls, and then bursts back through the inner wall to join the main flow again. You now have two channels open, one of which is a thin wall away from disaster. Successful non-surgical treatment requires that the blood-pressure is kept as low as possible to prevent a resurge.
