Is it possible for an ascending aortic aneurysm to shrink?

Not usually: Aortic aneurysms are generally degenerative processes. We use medications like beta blockers to keep it from expanding as quickly, but once begun, the process is usually progressive.

Not usually: But there is some variation in ct, mri, ultrasound so that one may see a report with a few millimeters ambiance: 4. 2. 4.3 4.1 probably no change. Also some after surgical repair or endovascular repair will be shrunk.
