Arteries: higher pressure, thicker walls, stretch (pulse) with each heart contraction & deliver blood to the arterioles which control the flow to individual capillaries. Veins are blood vessels which carry blood from capillaries back to the heart (body to right heart; ...Read more

If present in a patient, the discussion of appropriate therapy should take place with the attending Doc. ...Read more

Can stent be used to open 100% blockage in an artery such as LAD during cardiac catheterization procedure . Cons and pros please. Thank.

Can stent be used to open 100% blockage in an artery such as LAD during cardiac catheterization procedure . Cons and pros please. Thank.

Yes, if needed: Total blockage may occur suddenly - this is what causes a heart attack. Then the goal of the procedure is to get the blocked artery open asap (<90min) to save otherwise dying heart muscle. If the blockage is chronic, then it should be opened if the supplied muscle is alive and the patient's active lifestyle brings out symptoms. Stress scanning may be helpful to determine this. ...Read more

What happens to the bypassed artery and associated nerves after a bypass operation?

What happens to the bypassed artery and associated nerves after a bypass operation?

Artery atrophies: Typically the bypassed artery has no blood flow (hence the need for a bypass) and simply atrophies / scars down. The nerves are preserved and should not be affected by a bypass. The nerves in the skin which are cut during the procedure and cause skin numbness may improve over a six month period. Any numbness after 6 months is unlikely to get any better. ...Read more
