A weakened section of the aorta has widened.
Endovascular Aneurysm Repair (EVAR)Repair an aneurysm from inside the artery.
EVAR places a fabric-covered stent graft inside the aorta, creating a new path for blood and reducing pressure on the weakened aneurysm wall—without a large abdominal incision.
Not every aneurysm needs immediate repair. The recommendation depends on its size, growth, location, shape, symptoms, and your overall health.

What EVAR Does
EVAR lines the weakened part of the aorta with a stent graft. Blood moves through the graft, taking pressure off the aneurysm wall and lowering the risk of rupture.
How an Aortic Aneurysm May Be Found
Many abdominal aortic aneurysms cause no symptoms and are discovered on an ultrasound or CT scan. Others cause warning signs that should be evaluated promptly.
Found on an ultrasound
Seen on a CT scan
A pulsing feeling in the abdomen
Deep abdominal pain
Persistent back or side pain
Sudden severe pain or faintness

How Endovascular Aneurysm Repair Works
The specialist reaches the aorta through arteries in the groin and positions the graft with live X-ray imaging.
Reach the aneurysm
Through one or both groin arteries, guidewires and delivery catheters are advanced to the aorta.
Position the stent graft
The compressed graft is aligned above and below the aneurysm, then opened inside healthy portions of the artery.
Seal and confirm the repair
Blood is redirected through the graft. Imaging checks the seal, branch vessels, blood flow, and access sites before the catheters are removed.
EVAR vs. Open Aneurysm Repair
Both aim to protect the weakened aorta. The right approach depends on the aneurysm, your anatomy, and your overall health.
QuestionEVAROpen repair
Is EVAR Right for You?
A CT scan helps show whether the graft can seal safely and whether the access arteries can support the procedure. Your health and follow-up needs matter too.
Your evaluation should make these points clear:
- The aneurysm's exact size, location, shape, and growth.
- Whether there is enough healthy artery for the graft to seal.
- Whether the groin and pelvic arteries allow safe access.
- How kidney function and contrast imaging affect the plan.
- Whether standard, complex, or open repair fits the anatomy.
- How ongoing imaging will protect the repair long term.
What to Expect Before Treatment
Before repair, the team maps the aneurysm, checks whether the graft will fit, and gives you a clear plan for the procedure and follow-up.
Review the aneurysm
Your specialist reviews prior scans, symptoms, aneurysm growth, medical history, and any previous vascular procedures.
Plan the graft with CT imaging
CT angiography measures the aorta, sealing zones, branch vessels, and access arteries so the graft can be planned precisely.
Review medicines and safety details
The team checks kidney function, allergies, heart and lung health, blood thinners, fasting, and transportation instructions.
Choose the repair that fits
You receive a clear explanation of why EVAR, a standard or complex graft, open repair, or continued monitoring may fit best.
Recovery and Follow-Up
The procedure is only the beginning of aneurysm care. Recovery and follow-up depend on the graft, access sites, early imaging, and your overall health.
Hospital monitoring
The team checks circulation, kidney function, urine output, groin access sites, pain, and how you are recovering from anesthesia or sedation.
Protect the groin access sites
Walking, lifting, driving, bathing, wound care, and medicine instructions are tailored to your repair.
Check the graft seal
Early ultrasound or CT imaging confirms graft position, blood flow, and whether an endoleak or another issue needs attention.
Continue lifelong surveillance
Scheduled imaging, blood-pressure control, medicines, and smoking cessation help protect the repair and the rest of your vascular health.

Common Questions
Clear answers about EVAR, candidacy, recovery, and the follow-up needed to protect the repair.
What is EVAR?
EVAR is an image-guided repair for an aortic aneurysm. A fabric-covered stent graft is placed inside the aorta so blood flows through the graft and places less pressure on the weakened aneurysm wall.
Does the aneurysm go away after EVAR?
No. The aneurysm remains outside the graft. EVAR redirects blood through the graft to reduce pressure on the aneurysm, and follow-up imaging checks the seal and aneurysm over time.
Does every abdominal aortic aneurysm need repair?
No. Some aneurysms are monitored with regular imaging. Repair is considered when the risk of rupture becomes more concerning based on size, growth, symptoms, shape, location, and your overall health.
How is EVAR different from open aneurysm repair?
EVAR places a stent graft through arteries in the groin rather than replacing the weakened aorta through a large abdominal incision. Open repair may still be the better option for some anatomy or health situations.
How do you determine whether I am a candidate for EVAR?
CT angiography is used to measure the aneurysm, the healthy sealing zones, branch vessels, and access arteries. Kidney function, heart and lung health, prior procedures, and the ability to complete long-term imaging also matter.
What is an endoleak?
An endoleak means blood is still reaching the aneurysm outside the graft. Some endoleaks are observed while others need treatment, which is one reason scheduled imaging after EVAR is essential.
What should I expect during recovery?
Recovery varies with the repair and your health. The team monitors circulation, kidney function, and the groin access sites, then gives you individualized instructions for activity, medicines, wound care, and early follow-up imaging.
Will I need imaging for the rest of my life?
Long-term surveillance is part of EVAR care. The timing and type of ultrasound, CT, or other imaging depend on the graft, early findings, kidney function, and your specialist's plan.
Does insurance cover EVAR?
Coverage depends on medical necessity, your plan, network, hospital, and authorization requirements. EVSLA can review your plan details and explain the next steps before scheduling.
An aneurysm deserves a clear plan.
An EVSLA specialist can review your imaging, explain whether monitoring, EVAR, or open repair fits your anatomy, and guide you through the next step.
