Coil Embolization
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?
Coil Embolization usually takes 1-3 hours.
