WHAT TO EXPECT DURING YOUR PROCEDURE
Prior to the date of the procedure, you will undergo pre-procedure exams including an abdominal CT scan and possibly an angiogram. The imaging exam helps the radiologist visualize the aneurysm and determine the type and size of stent graft to use. You will also fill out paperwork and consent forms so the radiologist will know your medical history.
When you come in for the procedure, you will be asked to change into a gown. After answering any questions you have, a technologist will start an intravenous (IV) line in your arm. He or she will set up various devices so your heart rate and blood pressure can be monitored throughout the procedure. You may receive general or epidural anesthesia for the procedure, which will be done in an operating room.
The site of the groin incision will be cleansed. A fluoroscope will be moved into position above your abdomen. The groin incision will be made and the catheter will be inserted into the artery. Using the fluoroscope images, the radiologist will carefully thread the catheter to the location of the aneurysm.
The stent graft will then be deployed through the catheter to the aneurysm site. Once released from the catheter, the stent graft will expand to the appropriate size. The catheter will then be withdrawn and the incision will be sewn and taped. A CT scan or ultrasound is done so the radiologist can verify that the stent graft is properly placed.
The procedure takes between two and four hours to complete. You will then spend between one and three nights in the hospital.
