The EVAR procedure takes about 2-4 hours at Gates Vascular Institute and most patients are put under general anesthesia.
The procedure begins with two small punctures in both of the patients groins to access the femoral arteries. A delivery catheter (a long tube) is placed through the minimally invasive puncture site and guided up the leg via the femoral artery to the abdominal aneurysm.
Throughout the procedure, the vascular surgeon uses real-time x-ray images and contrast dye injections to visualize the aneurysm, catheter, and endograft without having to make a large incision.
The delivery catheter is then positioned to bring the endograft over the site of the aneurysm. The endograft directs blood through the graft itself and prevents blood from flowing into the aneurysm and potentially causing the aneurysm to rupture.
Next, two iliac limbs are attached to the main body of the endograft. Each iliac limb directs blood from the body of the graft to your leg. This creates a complete endograft system and a new, safer route for blood to flow to your legs without flowing into the aneurysm.
Lastly, your surgeon will inject contrast dye through the endograft system to assess the patients blood flow to ensure proper functioning of the endograft.
Patients, at a minimum, will spend 1 night in the hospital, and most are discharged the following day. For more information about EVAR, and to hear the procedure explained by a member of our team at BEVSA, click on the video below.
