How to Prepare for a Vascular Access Procedure

Prior to your procedure, your blood may be tested to determine how well your liver and kidneys are functioning and whether your blood clots normally.

Tell your doctor all medications that you are taking, including herbal supplements, and if you have any allergies, especially to local anesthetic medications, general anesthesia or to contrast materials (also known as "dye" or "X-ray dye"). Your doctor may tell you to stop taking aspirin, nonsteroidal anti-inflammatory drugs (NSAIDs) or a blood thinner for a specified period of time before your procedure.

Also tell your doctor about recent illnesses or other medical conditions.

Women should always inform their doctor or X-ray technologist if there is any possibility that they are pregnant. Radiation is not good for the fetus. If an X-ray is necessary, precautions will be taken to minimize radiation exposure to the baby.

You will receive specific instructions on how to prepare, including any changes that need to be made to your regular medication schedule.

You may be instructed to not eat or drink anything for several hours before your procedure.

You should plan to have a relative or friend drive you home after your procedure.

You may be asked to remove some or all of your clothes and to wear a gown during the exam. You also may be asked to remove jewelry, dentures, eye glasses and any metal objects or clothing that might interfere with the X-ray images.
