What is a vascular access?

For hemodialysis it is necessary to create a vascular access or pathway to your blood. The access is usually created in your arm during a short surgery. One type of access is a fistula, another type of access is a graft. In some cases an external catheter may be inserted into a vein in your chest or neck. A catheter is usually temporary and replaced by a fistula or graft.
