What is vessel occlusion?

Sometimes treatment for congenital heart disease (heart defects that are present at birth) will involve stopping blood flow through an unwanted blood vessel. The process of blocking the vessel is called occlusion. During the procedure to occlude the vessel, a thin, flexible tube (catheter) is inserted through a small incision site in the skin and threaded through a blood vessel to the point where the treatment will be administered. Devices such as a coil or small particles are placed in the unwanted vessel to prevent blood from continuing past that point.
