Aortic Dissection can be familial,
Once a familial trait has been found a family can use the information to keep dissection at bay.
This will differ from country to country as the richest countries will have access to a good understanding and medical technology to scan for changes within the vascular system.
This is a preventative measure but not a cure.
If aneurysms are found they can be treated surgically before Dissection occurs.
Healthy living and lifestyle with a good diet and keeping the blood pressure low is also a good preventative measure.
