Why is the doctor performing this procedure?
To stop
bleeding or abnormal blood flow within an artery. For example, coil embolization
can be used to:
- Close a Patent Ductus Arteriosus (PDA)
- Stop abnormal blood flow in an Arteriovenous
Malformation (AVM)
- Stop bleeding in an aneurysm
- Stop intestinal bleeding
What is the procedure?
Coil embolization is a
catheter-based procedure that allows precise occlusion of abnormal blood flow in
a blood vessel. A catheter with a metallic occluding coil is inserted into an
artery, usually in the groin (the femoral artery). It is then advanced to the
abnormal blood vessel. Once properly positioned, the metal coil is released,
springing into position within the vessel. It remains firmly in place by the
expansion of the metal coils. A blood clot will form on the coil, completely
obstructing the abnormal blood flow beyond the coil. Eventually a scar will
form, creating a permanent seal.
Where is the procedure performed?
In the Cardiac
Catheterization Lab
How long does this procedure take?

usually takes 1-3 hours
