the artery again.
So in summary, we've talked about dissection
and we've talked about renal artery stenosis.
• Dissection is a tearing of the inner lining
of the artery which allows a passage of blood
along a cleaved channel within the artery
• And as we talked about before, if not
repaired surgically or with a catheter-placed
stent, the dissection can rupture and be fatal.
• Renal artery stenosis is often associated
with the development of hypertension that
can be quite severe. And we're going to be
talking about hypertension in our next talk.
• Renal artery stenosis can be the result
of a congenital abnormal in the artery—that
is fibromuscular dysplasia—or it can result
from atherosclerosis; 95% of the time, it's
due to atherosclerosis.
• And treatment is in the form of antihypertensive
medication or by opening the blocked renal
