What to Expect During an Inferior Vena Cava Filter Placement or Removal Procedure
You may have blood drawn prior to your 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.
You should report to 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 physician may advise you to stop taking aspirin, nonsteroidal anti-inflammatory drugs (NSAIDs) or a blood thinner for a specified period of time before your procedure.
Also inform your doctor about recent illnesses or other medical conditions.
Women should always inform their doctor and 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 should eat a light meal the night before your procedure.
You may be instructed not to eat or drink anything after midnight before your procedure. Your doctor will tell you which medications you may take in the morning.
You may be allowed to drink clear liquids on the day of your procedure.
If you are diabetic and take insulin, you should talk to your doctor, as your usual insulin dose may need to be adjusted.
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, eye glasses and any metal objects or clothing that might interfere with the X-ray images.
You may want to have a relative or friend accompany you and drive you home afterward.
