WHAT IS VENOUS STENTING?
Venous stenting is a minimally invasive procedure used to improve blood flow when a vein is narrowed or compressed. This helps restore healthy blood flow. The stent is a wire mesh tube that is permanently placed in a vein and acts as a scaffolding to keep veins open.
WHAT ARE THE RISKS OF VENOUS STENTING?
• Bleeding, swelling caused by a collection of blood (hematoma), injury to nerves or infection.
• Damage to an artery or an artery wall. This can cause blood clots, abnormal ballooning of the artery, or abnormal link between the artery and nearby vein.
• Temporary kidney failure. Please notify your provider if you have had recent imaging testing that included contrast, as this would increase your risk for kidney issues.
TELL YOUR HEALTHCARE PROVIDER IF YOU:
• Are pregnant or think you may be pregnant. Radiation exposure during pregnancy may lead to birth defects.
• Are allergic to or sensitive to any medications, contrast, latex, tape, or anesthetic medicines (local or general). *Have kidney failure or other kidney problems. In some cases, the contrast can cause kidney failure. You are at higher risk for this if you take certain diabetes medicines. You may need to hold certain medications prior to the procedure.
• Are taking any medication that include prescriptions, over-the-counter, and herbal supplements.
• Have a bleeding disorder or take blood thinners, aspirin, or medications or supplements that affect blood clotting. These may have to be stopped prior to the procedure.
HOW DO I GET READY FOR A VENOUS STENTING?

Fluoroscopy is used to see the catheter. When contrast is injected, you may feel a warm, flushing sensation, salty or metallic taste, a brief headache, or nausea. These effects usually last for a few moments.

• If it is determined that an intervention is needed and can be done at that time, (percutaneous balloon or stenting) it can be done during the procedure. These procedures are included in the consent form as treatment possibilities.
• Once the procedure is completed, the physician will remove the catheters. Pressure will be applied to the site to keep it from bleeding. Manual pressure will be used to close the puncture site. After the bleeding stops, a dressing will be applied on the sites.
