Risks Of Endovascular Embolization
Infection, allergic reaction, excess bleeding, migration of coil, lower back pain, inflammation of the scrotum or the vein, and nausea are risks of embolization.
Dr. James Benenati, Director of Non-Invasive Vascular Laboratory at Miami Cardiac and Vascular Institute, says probably the worst thing on the list of risks is that one of these coils could migrate and leave the vein, and go maybe up to the lungs, but that's exceedingly rare.
