Vascular disease is a medical term given to the narrowing of blood vessels (arteries and veins). This type of disease occurs mostly in the heart, neck, and legs and if not caught or treated early, can cause serious health problems.
Regardless of where the narrowing occurs, diagnosis is crucial. To do so, the doctor makes a small puncture in either the femoral artery, near your groin area, or in the radial artery, near your wrist. A small hollow tube, called a sheath, is placed through the puncture site to allow your doctor access to your arteries, to visualize and, if necessary, treat the diseased vessel.
At the end of the procedure, the sheath is removed and a small hole, called an arteriotomy, remains in your artery. There are several methods and products designed to close the hole, including manual compression, sandbags, c-clamps, and a group of products called vascular closure devices.
