Veins are Blood Vessels
Veins are blood vessels that carry blood toward the heart. carry deoxygenated blood from the tissues back to the heart. Prior to placement of a fistula or consideration for a graft you are likely to undergo a venogram. A venogram requires the placement of an IV and then contrast is injected under a real-time X-ray machine to make sure the veins are open and big enough to use for a fistula. This “mapping” will then be used by a surgeon to create an appropriate access.
Occasionally veins in the arms/neck or legs/groin can become blocked or clotted requiring a procedure to re-open. This is safely done in an outpatient setting with minimally invasive techniques without general anesthesia.
