You will be given a combination of an epidural and a local anaesthetic for the procedure. The interventional radiologist will make a small cut at the top of each leg so that they can insert a short tube (known as a sheath), which allows the vessels in your groin to be accessed safely. Using fluoroscopy for guidance, the interventional radiologist will insert guidewires and catheters (thin flexible tubes). A contrast medium (dye) will be injected into the area being treated so the exact location of the aneurysm can be seen under imaging. The interventional radiologist will then use the guidewire to move a stent to the aneurysm.
When the stent is placed in the correct location, it will expand, sealing the aneurysm and restoring normal blood flow through the vessel.
After the procedure, your vital signs will be monitored and you will stay in hospital for 2-3 days. You may experience bruising and pain, though this can be treated with standard painkillers. Moving around once you are able to do so is encouraged. You will need to have the stent regularly checked using CT or ultrasound to ensure that it is in good condition and to avoid long-term problems.
